Interface graphs only showing in Graphite
by soren＠fab-it.dk 05 Mar '18

05 Mar '18

Hi list In my search for the missing link, I'm looking for a clue stick as to where my interface graphs disappear. I have installed Nav version 4.8.3 on Debian Stretch and currently monitoring two HP switches, ProCurve 2810 and 2910. The problem I have is in the "ranked statistics"-page, there is no interface traffic data in the graphs - instead I get a message: "No data was found for the given timeframe. This may indicate a problem with the data collection and/or presentation. Try choosing a longer timeframe to see when the problem started." But I do get graphs if I choose the "CPU highest average" - so SNMP apparently is working fine. When I access Graphite directly on port 8000 and traverse the tree Metrics-> nav-> devices-> ip-> port-> ifinOctets I am able to see a graph for that interface. What link between Nav and Graphite am I missing? Curiously I tried the shrink wrapped image on a VirtualBox and had the opposite problem. Monitoring another Procurve 2910 I only got traffic graphs and no "CPU highest average"-graphs. Kind regards Søren Aurehøj - Fab:IT

I'm left with only two possible options: 1. You are losing UDP packets (as mentioned by the debugging guide) 2. You are in fact experiencing a cache saturation problem with carbon-cache, but it's somehow being masked by its reporting of negative cache numbers. I'd try a newer version of carbon-cache if I were you, to see if that helps. If you are indeed experiencing cache saturation, a non-buggy version might expose it properly and you can take the necessary steps - such as running multiple carbon-caches or storing your Whisper files on an SSD (although I'll add, as I've done before, that we are running carbon-cache 0.9.10 in production, as upgrading to 0.9.12 gave us abysmal performance, with cache saturation on almost every installation - so even downgrading might help). If all else fails, you should contact someone within the Graphite project. See [1] or try #graphite on Freenode. [1] https://graphiteapp.org/ -- Morten Brekkevold UNINETT

How to add "Getting started" widget

I seem to have removed the "Getting started with NAV" widget from det default user, and now new users miss the opportunity to take the 30 second tour. How do I add this?

Is that a healthy carbon cache?
by Karl Gerhard 01 Mar '18

01 Mar '18

Hello, we're having problems with gaps in graphs (only for some interfaces) and I'm working through the https://nav.uninett.no/doc/4.8/faq/graph_gaps.html guide. I've arrived at the part with the "Carbon Cache" and I'd like to know whether those two graphs represent a healthy state: http://abload.de/img/e7zassl.png http://abload.de/img/jyz3sjf.png What strikes me as odd is that there are negative numbers, I can't see that on the graph on https://nav.uninett.no/doc/4.8/faq/graph_gaps.html Best regards Karl

Integrated Documentation Wiki
by cthompson＠egf.mn 27 Feb '18

27 Feb '18

Hello: Is there any efforts to add a "Wiki" or "Documentation" tab to netboxes and rooms? I'm thinking of integrating something like a mini wiki, like TiddlyWiki , in an additional tab for netboxes and rooms to have field editable configuration notes, etc. - maybe with the ability to store files to be associated with the device or room also (manuals, configs, drawings, photos, screencaps, et al). Looking to see if anything similar is being worked on, before I start studying the NAV code and look how to integrate such. Thanks Corey Thompson Technology Manager East Grand Forks Water and Light cthompson(a)egf.mn

Business report - linkDown, erroneous listings
by Ingeborg Hellemo 15 Feb '18

15 Feb '18

The business report for Link Availability are supposed to show links that are expected to be up but are experiencing downtime. Links that have never been up or that are down and the linkDown alert is acknowledged/cleared will not show up here. Have I understood this correctly? We now have a handful of links which have been down "forever", but NAV did at some point last Friday decide that the links were up, ended the linkDown status and shows the links in the business report with nn% downtime. All these links are still down and NAV thinks the link is Inactive. (It is possible that the NAV processes including ipdevpoll was restarted at the point the error was introduced) How can we clean up this mess and remove the links from the business report? --Ingeborg

Missing some uplinks
by cristina.caselles＠grupoversia.com 30 Jan '18

30 Jan '18

We updated our installation to 4.8.3 (Real Topology: some C2960 Cisco connected to a pair of Nexus) NetMap does not work properly (missing some uplinks). We edit IP Device info and, although NAV sees there links as unrecognized and after having added those unrecognized neighbors to NAV. Connections do not appear. Remote Name (as identified by NAV in unrecognized neighbors) is different from Sysname in the Seed Database (obtained from host file). Any suggestions? Is it better not to use host file? Does anyone work with Nexus? Best Regards, Cris

Feedback about the new IP Device Info
by René Romijn 12 Jan '18

12 Jan '18

Hi, We used the old layout in the function IP Device Info a lot in NAV and we are trying to get used with the new layout but here are some comments about it: * With the new layout with switches > 24 ports or 48 ports you have to scroll down to see the active/inactive ports, the old view give you on one page all the ports. * The 'last used' is stated 'Never' for uplinks, this is kinda confusing. * With the old layout you could use with the switch activity tab the history of some amount of days to check activity so you could see very fast wich ports arent used. Now you see the last date (except for the uplinks), but the older view was more easier. Curious about other people's oppinions. Kind Regards, René.

NAV snmptrapd handler help!
by Zhi-Wei Lu 14 Des '17

14 Des '17

Hi NAV gurus, I am in the process of learning how to use the snmptrapd handler for NAV. I hit a few road blocks along the way. I first test a simple home-made snmptrap (V1), what is the procedure to incorporate it into NAV snmptrapd. Where do I put the text mib files? /usr/share/snmp/mibs? Do I need to convert the text mib file into *.py in the directory (using smidump ?) /usr/share/pyshared/nav/smidumps ? I need to modify /etc/nav/snmptrapd.conf to add our own handler and put it in /usr/share/pyshared/nav/snmptrapd/handlers/ In my trap handler, I need to tell it process the trap with trap.genericType match what we define it. But I still could not get it to work properly. I would appreciate if someone can point me to the right direction, as I still miss a few pieces here and there. Thank you.

nav log time stamp issues: local time and UTC on different log files
by Zhi-Wei Lu 11 Des '17

11 Des '17

Hi NAV gurus, I noticed that some of the NAV log files use "local time" (here in California), 2017-12-07 15:56:13,973 [INFO] [nav.statemon.db] Returned 0 checkers while the other use UTC+1 in time stamp: 2017-12-08 00:50:14,898 [INFO] [nav.snmptrapd] Snmptrapd started, listening on 0.0.0.0:162, [::]:162 What do I need to make all log files using the local time stamp? Thank you. Zhi-Wei Lu IET-CR-Network Operations Center University of California, Davis (530) 752-0155

Netmap showing connections that do not exist anymore
by Oscar Patricio 08 Des '17

08 Des '17

Hi, I have been using NAV for quite some time and I am really satisfied with the tool. So much so, that I implemented it at my new job. That being said :) I have a question: the Netmap application is showing me connections that do not exist anymore. This means, they were once established, but have been disabled (I am talking about connections between two network switches, between which the cables have been removed and the interfaces have been shutdown) a couple of months ago. Because the network I am managing is not very big, this is not a big problem because I know those connections in the Netmap are "fake". This is, however, a bit annoying, and I would like the map to reflect the actual topology of the network. So my question is: is there any way that I can force a redrawing of the map? Or a way to force nav to delete that connection from its database? Thanks in advance!

New to NAV, supported devices
by Vinsonnaud Ludovic 07 Des '17

07 Des '17

Hello, Sorry about my english, I'm french so everything may not be understood :-) I'm new to NAV and this software seems very interesting for my needs. I'm managing the network in an Engineer School (IOGS) and CNRS Labs (LCF and LP2N) based in 2 sites (near Paris and near Bordeaux). I've got an heterogeneous group of switches because we begin to change our 100Mb switches by 1Gb and 10Gb ones. For the moment we own : - Dell S4048-ON (force10) used for routing - Dell N2048 - Dell N4064 - Cisco 2960s - Cisco 3750 My switches are recognized pretty well after some tweaking. For Cisco 2960, everything works. Sometimes I've got timeout and "failed" changes so I need to wait before trying again (especialy vlan change). For Cisco 3750, it's the same For Dell N2048, I'm a bit confused because if I have this command "switchport access vlan 524" already set in the switch and I ask to change the vlan from 524 to 525 with NAV, it adds this command "switchport general pvid 525" but doesn't delete the old one. So why change a "switchport access" by a "switchport general" ? Is it better to have a "switchport mode general" in default config ? Switchport mode access is the default mode, the 2 combined commands will not work as intended I think ? I've not yet tested S4048 and N4064. -- Regards, IOGS Logo <https://www.institutoptique.fr> *Ludovic Vinsonnaud * - Ingénieur Réseau basé à Bordeaux, bureau F108 (IOA, Rue François Mitterrand, 33400 Talence) *Institut Optique Graduate School* 2 Avenue Augustin Fresnel - 91127 PALAISEAU Cedex Tel. +33 5 57 01 71 52 - Mob. +33 6 08 08 41 05

Hello all, I just updated our installation to 4.8.0. I noticed however, that there seems to be an issue with multicore mode with ipdevpoll. It seems to no longer work. Only one process runs, or it doesn't seem to run at all. Anybody else encounter any issues with this? Thanks William Daly Network Specialist (707) 453-6170

Changing Link Capacities Netmap
by William Daly - Network Specialist, VUSD Technology 08 Nov '17

08 Nov '17

Hello, I have sort of a different question. Here a bit of context: We currently have 17 sites throughout our school district. All of these have a 1Gbps uplink to our main district office. However, most of these sites are throttled at 100 Mbps. Of course NAV sees these links at 1 Gbps. The issue that I have is when viewing our network topology through Netmap it shows bandwidth usage based on 1 Gbps. However, the sites run at 1/10 the actual link capacity. Is there a way to 'change' Netmap to show bandwidth usage based on a different threshold? Thank you William Daly

Multicore support IPdevpool and Django Errors
by William Daly - Network Specialist, VUSD Technology 16 Okt '17

16 Okt '17

Hello, I am currently experiencing an issue with multicore with IPdevpool being enabled and encountering many errors. Essentially when I enable multi core support, the web gui stops rendering graphs at a high frequency and things do not load. In the logs it appears it shows errors with django. As soon as multi core support is turned off everything returns to normal, however my graphs become very spotty. Thanks, Will

Prefix and VLAN problems
by William Daly - Network Specialist, VUSD Technology 13 Okt '17

13 Okt '17

Hello, I am also having issues with prefixes and the corresponding VLAN tab. Initially, I went through and entered in all of my prefixes, with corresponding VLAN's, net identifications and usage type. However, after I populated the data base with nodes, the prefixes disappear and now when I go to the VLAN tab, all that shows is the net type and VLAN. I cannot edit net identifications. When I go to edit and change the organization and description, none of the changes hold. Any ideas? Thank you William Daly

Webfront authentication with encrypted LDAP to Windows Server fails
by Roger Aas 28 Sep '17

28 Sep '17

Hi, I have the NAV webfront LDAP authentication working with a Windows AD server, but only with unencrypted traffic on port 389. In the file /etc/nav/webfront/webfront.conf port = 389 encryption = none It works well with search for user in the AD tree and group requirement. But if I change encryption to tls, or port to 636 and encryption to ssl then it fails. Anyone have this working? If yes, what did you have to do to get it to work? I can not use it as it is as both the user account used for binding to the server and the user trying to authenticate have their passwords in cleartext in the packets. Best regards, Roger

ServiceState alert showing in UTC timezone
by Bruce Zhang 14 Sep '17

14 Sep '17

Hi there, Sorry to bother you all again. It's really wired. I have changed time_zone in nav.conf and all time is correct on the front page. But only the Service state alert's start time and end time is showing in UTC timezone. I went through database and confirmed those time was recorded by UTC timezone, as below: SQL: select * from manage.alerthist As you can see, the other’s alert in thresholdState is correct. I also looked into python code, In python/nav/models/event.py class AlertQueue(models.Model, EventMixIn): time = models.DateTimeField() class AlertHistory(models.Model, EventMixIn): start_time = models.DateTimeField() I changed those code to models.DateTimeField(default=dt.datetime.now), but still got same issue. I was just wondering has anyone run into the same problem? Cheers. Bruce

Could we updated NAV port metrics every 1 min?
by Bruce Zhang 11 Sep '17

11 Sep '17

Hi all, I am a network administrator and new to NAV. I really like NAV and am going to use it. But I found the Port Metrics Traffic graphs is updating every 5 mins.(I knew it's default intervals for NAV) I want to get more accurate Port traffic graphs, so could we change it from 300s to 60s? I did research and changed storage-schemas.conf(added 60s:1d) and used whisper-info to ensure those ports traffic wsp files have been changed to 60s. But I still can't get correct data via rickshaw JS and NAV still collected data in every 300s. So is that possible to change it? Or someone can point me to the right direction? Thanks. Bruce

Delayed alerts
by Roger Aas 04 Sep '17

04 Sep '17

Is it possible to configure alerts for a boxdown alert to be sent after a specified amount of downtime, f.ex. 4 days? I have a customer with some Cisco IR809 industrial routers installed on LNG trailer trucks that go active when the trailer is started and goes down when the trailer is parked. This means the router goes down and comes up all the time, we do not want alerts for that. But if the router does not become active after f.ex. 4 days the customer would like to get a message about that, maybe it means there is some other problem with the connection that they need to check. Is this possible with NAV? I only find "weekly at predefined time", but if I set the "Weekly dispatch time" to "08:00" and "Weekly dispatch day" to "monday", and the truck is parked Sunday evening, I will get a message Monday morning that it is down, even if it has been down for just some hours. I basically want a to be able to set a delay for alerts that counts down a specified amount of minutes/hours/days before sending a boxdown alert. Best regards, Roger

Getting GPS data from routers
by Roger Aas 01 Sep '17

01 Sep '17

Some models of Cisco routers have inbuilt GPS antennas and it is possible to get location data from the router, using both CLI and SNMP. Is it possible to add code in NAV to import this GPS data into the "Position" field in the "Rooms" data? For routers that are in a static location it means the location will be correct, not a best effort by pointing on a map. :-) For routers that are in motion it means it is possible to track them and at least know the last location. lng-truck-1-L22#show cellular 0 gps detail GPS Info ------------- GPS Feature: enabled GPS Port Selected: Dedicated GPS port GPS State: GPS enabled GPS auto tracking status: unknown GPS auto tracking config: disabled GPS Mode Configured: standalone Latitude: 60 Deg 28 Min 54.7647 Sec North Longitude: 5 Deg 23 Min 22.7313 Sec East Timestamp (GMT): Wed Aug 30 09:46:56 2017 Fix type index: 0, Height: 81 m HDOP: 0.8, GPS Mode Used: standalone Satellite Info ---------------- Satellite #2, elevation 17, azimuth 42, SNR 34 Satellite #9, elevation 11, azimuth 347, SNR 35 Satellite #16, elevation 17, azimuth 288, SNR 39 Satellite #21, elevation 25, azimuth 177, SNR 38 Satellite #23, elevation 15, azimuth 320, SNR 42 Satellite #25, elevation 27, azimuth 123, SNR 43 Satellite #26, elevation 45, azimuth 282, SNR 46 Satellite #29, elevation 65, azimuth 88, SNR 34 Satellite #31, elevation 45, azimuth 222, SNR 43 Satellite #5, elevation 16, azimuth 75, SNR 0 Satellite #20, elevation 6, azimuth 118, SNR 0 roger@nav:~$ snmpwalk -On -c secretpw -v 2c 10.140.73.1 1.3.6.1.4.1.9.9.661.1.4.1.1.1 .1.3.6.1.4.1.9.9.661.1.4.1.1.1.1.16 = INTEGER: 2 .1.3.6.1.4.1.9.9.661.1.4.1.1.1.2.16 = INTEGER: 2 .1.3.6.1.4.1.9.9.661.1.4.1.1.1.3.16 = INTEGER: 48 .1.3.6.1.4.1.9.9.661.1.4.1.1.1.4.16 = STRING: "59 Deg 25 Min 24 Sec North" .1.3.6.1.4.1.9.9.661.1.4.1.1.1.5.16 = STRING: "5 Deg 25 Min 26 Sec East" .1.3.6.1.4.1.9.9.661.1.4.1.1.1.6.16 = STRING: "GMT: Wed Aug 30 10:00:17 2017 " .1.3.6.1.4.1.9.9.661.1.4.1.1.1.7.16 = Gauge32: 0 .1.3.6.1.4.1.9.9.661.1.4.1.1.1.8.16 = Gauge32: 0 .1.3.6.1.4.1.9.9.661.1.4.1.1.1.9.16 = Gauge32: 0 .1.3.6.1.4.1.9.9.661.1.4.1.1.1.10.16 = INTEGER: 2 .1.3.6.1.4.1.9.9.661.1.4.1.1.1.11.16 = INTEGER: 1 .1.3.6.1.4.1.9.9.661.1.4.1.1.1.12.16 = INTEGER: 19 .1.3.6.1.4.1.9.9.661.1.4.1.1.1.13.16 = Gauge32: 0 .1.3.6.1.4.1.9.9.661.1.4.1.1.1.14.16 = INTEGER: 2 .1.3.6.1.4.1.9.9.661.1.4.1.1.1.15.16 = Gauge32: 0 .1.3.6.1.4.1.9.9.661.1.4.1.1.1.16.16 = Gauge32: 0 .1.3.6.1.4.1.9.9.661.1.4.1.1.1.17.16 = Gauge32: 0 .1.3.6.1.4.1.9.9.661.1.4.1.1.1.18.16 = Gauge32: 0 .1.3.6.1.4.1.9.9.661.1.4.1.1.1.19.16 = Gauge32: 11 1.3.6.1.4.1.9.9.661.1.4.1.1.1.1 (c3gLbsModeSelected) 1.3.6.1.4.1.9.9.661.1.4.1.1.1.2 (c3gLbsState) 1.3.6.1.4.1.9.9.661.1.4.1.1.1.3 (c3gLbsLocFixError) 1.3.6.1.4.1.9.9.661.1.4.1.1.1.4 (c3gLbsLatitude) 1.3.6.1.4.1.9.9.661.1.4.1.1.1.5 (c3gLbsLongitude) 1.3.6.1.4.1.9.9.661.1.4.1.1.1.6 (c3gLbsTimeStamp) 1.3.6.1.4.1.9.9.661.1.4.1.1.1.7 (c3gLbsLocUncertaintyAngle) 1.3.6.1.4.1.9.9.661.1.4.1.1.1.8 (c3gLbsLocUncertaintyA) 1.3.6.1.4.1.9.9.661.1.4.1.1.1.9 (c3gLbsLocUncertaintyPos) 1.3.6.1.4.1.9.9.661.1.4.1.1.1.10 (c3gLbsFixtype) 1.3.6.1.4.1.9.9.661.1.4.1.1.1.11 (c3gLbsHeightValid) 1.3.6.1.4.1.9.9.661.1.4.1.1.1.12 (c3gLbsHeight) 1.3.6.1.4.1.9.9.661.1.4.1.1.1.13 (c3gLbsLocUncertaintyVertical) 1.3.6.1.4.1.9.9.661.1.4.1.1.1.14 (c3gLbsVelocityValid) 1.3.6.1.4.1.9.9.661.1.4.1.1.1.15 (c3gLbsHeading) 1.3.6.1.4.1.9.9.661.1.4.1.1.1.16 (c3gLbsVelocityHorizontal) Best regards, Roger

Fresh install - Geomap error

I recently did a fresh install of nav on Debian Jessie. Everything is working except geomap, when navigating to http://nav-server/geomap/normal/ i receive an alert via mail with the following information: Internal Server Error: /geomap/normal/data Traceback (most recent call last): File "/usr/lib/python2.7/dist-packages/django/core/handlers/base.py", line 111, in get_response response = wrapped_callback(request, *callback_args, **callback_kwargs) File "/usr/lib/python2.7/dist-packages/nav/web/geomap/views.py", line 163, in data do_fetch_data) File "/usr/lib/python2.7/dist-packages/nav/web/geomap/views.py", line 210, in get_formatted_data output = format_data(format_, features) File "/usr/lib/python2.7/dist-packages/nav/web/geomap/output_formats.py", line 96, in format_data return formatter(featurelist) File "/usr/lib/python2.7/dist-packages/nav/web/geomap/output_formats.py", line 45, in make_geojson return json.dumps(geojson) File "/usr/lib/python2.7/json/__init__.py", line 243, in dumps return _default_encoder.encode(obj) File "/usr/lib/python2.7/json/encoder.py", line 207, in encode chunks = self.iterencode(o, _one_shot=True) File "/usr/lib/python2.7/json/encoder.py", line 270, in iterencode return _iterencode(o, 0) File "/usr/lib/python2.7/json/encoder.py", line 184, in default raise TypeError(repr(o) + " is not JSON serializable") TypeError: <lazy_dict {'color': '#666666', 'popup': {'content': u'<div class="place-popup">\n\n <table class="listtable">\n <tr>\n <th>Rooms</th>\n <th>IP devices</th>\n <th>CPU load (max)</th>\n </tr>\n <tr>\n <td>1</td>\n <td>1</td>\n <td>unknown</td>\n </tr>\n </table>\n\n \n <table class="listtable">\n <caption>\n <a href="/search/room/MEKU-2ETG-EF-02/"\n target="_blank"\n title="View room information">\n MEKU-2ETG-EF-02\n (Etasjefordeling #2 - MEKU)\n </a>\n </caption>\n\n <tr>\n <td><b>IP Devices:</b> 1</td>\n <td><b>CPU load (max):</b> unknown</td>\n </tr>\n\n <tr>\n <td colspan="2">\n <ul class="large-block-grid-2">\n \n <li>\n <h5>\n <a href="/ipdevinfo/sw-meku-03.net.domain.no/"\n target="_blank"\n title="View in IP Device Info"> sw-meku-03.net.domain.no</a>\n </h5>\n <ul class="no-bullet">\n <li><b>IP:</b>10.10.10.10</li>\n <li><b>Category:</b> SW</li>\n <li><b>Type:</b> Cisco C2960S</li>\n <li><b>Up:</b> y</li>\n <li><b>Load:</b> unknown</li>\n </ul>\n </li>\n \n </ul>\n </td>\n </tr>\n\n </table>\n \n\n</div>\n', 'closable': True, 'id': 'popup-cn[cn[37]]', 'size': [300, 250]}, 'type': 'node', 'size': 4}> is not JSON serializable I guess there's a step i forgot, but can't figure out what it is. -- MVH / REGARDS: Espen Lorentzen esplor(a)gmail.com

Outdated cam records
by Andreas Dobloug 24 Aug '17

24 Aug '17

Hi, we're having trouble with outdated cam records on some of our switches: nav seems to only collect cam records from a random subset of ports on each switch. We're tried snmpwalking the switch, and it seems like the mac addresses are reported correctly by the switch. This occurs both on nxos (Nexus) switches and older IOS switches best regards Andreas Dobloug University of Oslo

Hi, I see some graphs in NAV and some not. Particularity the Etherports are empty? Sensors tab shows graphs. Graphite on port 8000 works and shows devices and graphs. The only thing I can find in the log is: [WARNING] [pid=526 nav.django.auth] User default denied access to /search/? query=10.100.5.1 Which in my noobie experience with NAV and Graphite i cannot make out what is wrong? I cannot find anything for days now in any google serach on NAV installs.... Cheers Erik

Basic NetMap Question
by fgsilva＠gmail.com 15 Mai '17

15 Mai '17

Hello, I have downloaded NAV to test in my company. I have installed the software and configured around 30 production switches and routers to see how the tool works. Everything is going well except for one point. When I open the Netmap module, I can see a graphic representation of all devices on the page, however the lines connecting the devices are all green even if the device is reporting down. (If I click on it there is a red icon on the top right side of the window). My question is, what is the criteria to change the graphic representation to red ? E.g. If the device is not reporting SNMP but it is replying ping, should the status be green ? Thanks in advance, Fernando.

Duplicate arps on prefixes with hsrp.
by Jan Sigurd Refvik 27 Feb '17

27 Feb '17

Hello all. We have recently noticed that machine tracker will report duplicate arps on every entry on networks running hsrp. Looking at the gwportprefix.virual, it is set to 't' for the 'virtual' interfaces and 'f' for the 'real' interfaces. Seems right. I believe only the active interface should be collected, or have I missed something? Any magic wands or switches? The 2 'real' interfaces are entered in the seed database, not the virtual. We do not use the NTNU port description convention. We are running nav 4.6.1 and the last schema update is 4.6.56. Any thoughts here? Regards

PortAdmin - save changes in HP 5130 switch?
by Mattias Söderholm 13 Feb '17

13 Feb '17

Hi. We have now inserted some HP 5130 EI (also HP 5700) switches in NAV and want to use PortAdmin. Everything works except saving to memory. The problem is the save command! For HP Procurve switches you use "save" or "write memory" commands to save changes and it's done. HP 5130 EI is a little bit different. There you must use "save force", if you only use "save" command you have to answer some questions. Can this be fixed? Regards Mattias

A new package for Debian Jessie is published in our APT repository [2], as usual. The virtual appliance will be updated shortly. Changes ======= NAV has moved to GitHub. Issues are now tracked at [3]. Due to the migration of bug data from Launchpad, reporter and subscriber information has been lost (all bugs appear to be reported by jmbredal).

I have read the documentation http://graphite.readthedocs.io/en/latest/render_api.html#from-until, but as I am not so expert, it is a bit hard to understand. But I am trying again...

If yes, how can I proceed ? Hi Cedric, it would normally be possible, but due to a bug [1], it won't be possible again until the next bugfix release (unless you manually apply the bugfix patch from [2]). The "normal" way of customizing your graph would be to alther the graph URL from the widget's edit panel. You'll want to look at the from/until arguments, as described in Graphite's own docs at [3]. In closing, I ask that you please post these kinds of questions on the nav-users mailing list in the future, so the information/discussion can be of benefit to everyone :-) [1] https://bugs.launchpad.net/nav/+bug/1647664 [2] https://nav.uninett.no/hg/nav/rev/59196ae30fe7 [3] http://graphite.readthedocs.io/en/latest/render_api.html#from-until -- mvh Morten Brekkevold UNINETT

Switching to GitHub
by Morten Brekkevold 18 Jan '17

18 Jan '17

Hello all, As we will be involving more people from UNINETT in NAV development over the coming year, we have decided to spend some time on consolidating our workflow tools. In short, "we want to be using the same tools as other developers at UNINETT are using these days". This will have the following effects for NAV in the coming days and weeks: * We will switch from using Mercurial as our version control system, to using Git. * We will host our Git repository at GitHub, under the UNINETT organization [1]. * We will transfer existing bug reports from Launchpad into GitHub issues, then disable the Launchpad project. * The mirror repository at BitBucket will be removed. * The nav-debian package repository will also move from Bitbucket to GitHub. The most finicky part of this transition will be the migration of bug reports from Launchpad. GitHub only provides a rate-limited API to manipulate issues, which means migration of all reports may take days once started. Most likely, if you have reported or are otherwise subscribed to bug reports at Launchpad, you will have to re-subscribe at GitHub to continue to receive updates as bugs are worked on.

NAV API endpoint for useradmin
by Mischa Diehm 12 Jan '17

12 Jan '17

Hi all, I’m wondering if you also see a valid demand in having the useradmin interface as an API endpoint. We use „web_access“ privs a lot and it is always a pain if sth. changes for a given group (either in the set of switches we allow access to or in the networks we give privs to). We usually have to delete all the privs and put in the new ones. My question to you: do you have a better way to deal with this and if no would an exposure through the API help you with that?

Removing Apache Dependency Requirement?

NAV Migration

Hi We recently upgraded from 4.4.3 to 4.5.3 by building a new server with the supplied ovf file, and migrated the database using the procedure referenced in the following link. https://nav.uninett.no/doc/4.5/howto/migrate-data.html The cli command we used to restore used the --drop-database --create --restore switches on the new server. We now not the directory structure seems for the cam, arp folders is now / api/1/arp, whereas on the 4.4.3 box it was /api/arp. Is this due to the restore method we have used or has the directory structure changed Many thanks

Additional equipment OID addition.

Hi, I'm working on a project to replace all polled data collections we have running on Cacti for our network devices ( Cisco, F5, Brocade, Sanbox, ..... ) to graphite. Actually your tools is the only one using graphite out of the box and I was wondering how much work it would be to add unsupported monitoring MIBs and if there would be some example other than https://nav.uninett.no/doc/4.2/hacking/adding-environment-probe-support.html ? Actually all exotic devices are showing values for their network interfaces but most are not retrieving CPU/Memory and other specific data. Thanks Marc TRANI

Problem: NAV alerts not working
by Patricio, Oscar (Coriant - PT/Lisbon) 22 Sep '16

22 Sep '16

Hi all, I've been trying NAV out for the third time now, as I am experimenting with several similar tools. First of all, I really like NAV and it is the tool that shows the most potential from all I tried, in terms of network monitoring. BUT (there is always a but in theses emails), I am having trouble getting thresholds and their respective alerts to work. I have really kept my installation to the simples possible, so at the moment I only have one device and I have only setup one single threshold, purposefully so that it immediately is exceeded. But after I do that, there is no event and it is as though the threshold has not been exceeded. When I look into the thresholdmon.log this is what I see repeatedly: 2016-09-21 14:40:01,992 [INFO nav.thresholdmon] evaluating 1 rules 2016-09-21 14:40:02,513 [WARNING nav.thresholdmon] did not find any matching values for rule u'nav.devices.XXXXXXXXX.ports.Bridge-Aggregation1.ifInOctets' <50% 2016-09-21 14:40:02,513 [INFO nav.thresholdmon] done What does this mean? This interface has traffic and that traffic is beeing graphed without issues... So my question is: what am I missing? This is supposed to be very simple to configure but apparently does not work. Am I doing some basic error? Thank you for your attention. Best regards, Óscar

The `-f` switch is to run ipdevpoll in the foreground instead of the background. You will still need to add the `-s` switch if you want output to your terminal and not just to the log file. You can manipulate log levels of various parts of NAV using the `logging.conf` configuration file. There are some examples of level configuration in that file already, but you can add `nav.ipdevpoll = DEBUG` to debug-log everything ipdevpoll-related (which can be quite a lot of output). -- mvh Morten Brekkevold UNINETT

Netmap question
by etiennel＠cos.flag.org 12 Sep '16

12 Sep '16

Hello, Very nice piece of software - most useful network monitoring tool I have seen in the open-source world. I have a question on the Netmap tool - I'm trying to have external links show and I wasn't able to. The scenarios are: - Edge router connected to the ISP. I can't add the ISP as a netbox as I don't have SNMP query access. So I added it as a server. How can I show on Netmap the edge router, the ISP end-device with a link between the two so I can see the bandwidth utilization and status? - A similar scenario, but with VPNs. I have a VPN router with multiple Tunnel interfaces (Csico) establishing a VPN with remote offices. I don't have SNMP of the remote offices' routers. How can I show this in Netmap tool - showing my VPN router with links to remove devices. I was able to do a similar thing with computers plugged into my switches, but in this case, I guess NAV uses the MAC address to match the device (in this case environment monitoring) with the switch port. Thank you. Etienne

NAV and API exports

Hi, We are programming an inventory tool that uses NAV as one of its main datasources. We are now trying to get the Serial (lots of cisco here) for a given device. In the ipdevinfo overview we see the serial (for stacks there are even the stackmembers with serials listed). My questions is if we there is a way to get this information through the API and if yes how we could retrieve it? My second questions is if there is an easy documented way to extend the API with stuff like that or e.g. Status info like „is the box currently online“? Is there a roadmap towards what should and will be implemented regarding the exporsure through the API (maybe even write stuff?)

"Reversed" netmap view
by Kadlecsik József 07 Apr '16

07 Apr '16

Hi, Instead of the real topology ----------- gsw17a (SW) | kfki-sw (GSW) ---- gsw21 (SW) --- gsw21alag (SW) | ----------- gsw22a (SW) netmap shows a "reversed" topology, as shown in the attachment (full.png), i.e. gsw21 is the farthest from kfki-sw and gsw17a, gsw21alag, gsw22a "connect" gsw21 to kfki-sw. The IP device Neighbors of gsw21 shows the proper topology (gsw21.png) except that kfki-sw is not shown. The IP device Neighbors of gsw21alag shows the wrong topology: neighbor is kfki-sw instead of gsw21 (gsw21alag.png), the same true for gsw17a and gsw22a. The direct neighborship candidate is (partly) consistent with this (other fields are empty, non-related, invalid neighbors not listed): Sysname Interface source Candidate neighbor gsw17a 1/48 cam kfki-sw gsw21alag 1/24 cam kfki-sw gsw21 1/45 cam kfki-sw gsw21 1/107 cam gsw21alag gsw21 1/111 cam gsw17a gsw21 1/112 cam gsw22a gsw22a 1/48 cam kfki-sw kfki-sw Gi1/6 cam gsw17a kfki-sw Gi1/6 cam gsw21alag kfki-sw Gi1/6 cam gsw21 kfki-sw Gi1/6 cam gsw22a The switch types are: kfki-sw Cisco 6506-E gsw21 D-Link DSG-3120-48TC gsw17a D-Link DSG-3120-48TC gsw21alag D-Link DSG-3120-24TC gsw22a D-Link DSG-3120-48TC What can be wrong here?

Cisco - linux connection not recognized
by Kadlecsik József 07 Apr '16

07 Apr '16

Hello, We run nav 4.4.3 and are facing a strange problem: A Cisco 6500 (GW) ---- Linux with snmpd (GW) ---- B Cisco 6500 (SGW) Netmap shows that Linux - B Cisco are connected but does not show the connection between A Cisco - Linux. A Cisco IP Device Info, Neighbors does not list Linux. Linux IP Device Info, Neighbors lists neither A, nor B Cisco as neighbor. B Cisco IP Device Info, Neighbors lists Linux as neighbor. The Direct neighborship candidates does not list the connection between A Cisco and Linux. Linux has got IP addresses at both interfaces and added to the database with the IP address facing to B Cisco. We added the suggested interface descriptions to both Ciscos but it did not help. What could we do to get the connection recognized?

Portadmin - Problem with changing Vlan
by Mattias Söderholm 18 Mar '16

18 Mar '16

Hi. For a couple of week ago we could change Vlan in portadmin and save with our HP 5130 switches. But now with Nav 4.4.2 it only show error when saving. It says: Error setting vlan: SNMP Error: inconsistentValue (The set value is illegal or unsupported in some way). What can be the problem? There is error when we try to check connectivity for snmp for one of the switches via SeedDB also. That's because there's something wrong with Chassis detected. It got two Chassis detected and one is down. I have tried to delete the switch and added it again, but the N/A chassis is appearing after a while again! 5130-EI (serial: XXXXXXX, software: 7.1.045 Release 3109P05) <---- Down N/A (serial: N/A, software: 7.1.045) <--- Don't know where this comes from Regards Mattias

No. You should probably look into RANCID [1]. There was at some point some ideas to integrate RANCID and NAV, but the resources were never allocated. At UNINETT we extensively use tftp to store device configs, but storing a running config to the tftp serverr must be initiated from the device itself. RANCID is more proactive in this regard.

post installation question
by Don Click 29 Jan '16

29 Jan '16

Gents - first, thank you for an awesome tool to help manage the network. I recently did a fresh install of Debian and installed the NAV packages (including graphite). However, when we are adding our devices, they are all coming back with NO PORTS FOUND, or NO POWER SUPPLIES, NO FANS, etc. I am not seeing any logs in the /var/logs/nav area, so I am not sure what is really happening here. I have tried searching through the mail-list, but so far, I am not finding any possible suggestions or clues. When I evaluated the virtual appliance, this seemed to work quite well. (I wasn't able to get the virtual appliance to migrate to our production environment). Would someone be so kind as to point me in a direction that may help me troubleshoot this? Thank you!

Hi All, I just uploaded my latest project Arnold related ArnoldTrigger <https://github.com/tbaror/ArnoldTrigger>, this project is TCP client agent/server based ,that is basically triggered upon in our case Symantec clients infection. This need is came out of need to make sure that clients are well cleaned in case of infection and make sure isolated from network until we make sure its well cleaned. In current version we have the client query the infection event confiured in "js" file and sends json format ssl encrypted with pre-configured key authenticated to server , when authentication is completed the server send "start_arnold" ip with date+machine name file inside Machine IP, and the machine is sent to quarantine preconfigured profile that we set. we are working now on two major features autocleaning module , and Firewall (pfsense) snort events to Arnold. Hope you find this tool useful , and i will gladly will get any comments and suggestion for improvements. Thanks -- Tal Bar-or

Heads-Up: Cisco bug prevents NAV settings to be written to running-config
by Mischa Diehm 20 Okt '15

20 Okt '15

Hi, if you upgrade to recent versions on your cisco infrastructure and have a distributed setup of admins using NAV/snmp to tell the device what to do, you will lose all your configuration as soon as your device reboots as the changes you made are not written into the running-config! So heads up and be warned. -m - https://tools.cisco.com/bugsearch/bug/CSCuu48624/ adding port to vlan via SNMP not in running-config on cat4k IOSXE CSCuu48624 Description Symptom: Adding port to a vlan does not update running-configuration with "switchport access vlan X" command, hence after reload port would go back to VLAN 1 (default). Conditions: 03.07.00 or 03.07.01 software version catalyst 3k/4k assign port to a vlan via SNMP (snmpset -v2c -c test 10.106.69.151 1.3.6.1.4.1.9.9.68.1.2.2.1.2.6 i 255) Workaround: assign port to a VLAN manually through CLI via "switchport access vlan X" command Further Problem Description: When assigning VLAN to the access port on the switch using setSNMP (snmpset -v2c -c test 10.106.69.151 1.3.6.1.4.1.9.9.68.1.2.2.1.2.6 i 255) port does not get any configuration in show running-config interface output.

NAV supporting Cisco Voice VLANs
by Mischa Diehm 13 Okt '15

13 Okt '15

Hi, we are looking into using NAV with Cisco IP-Phones (8841/8851 series) and while trying the feature we realized the config put on the port doesn¹t use the cisco proprietary settings but sets the port into trunk. What we want to achieve is using an additional voice-vlan on the port like:: Switch(config)#interface range fastethernet 0/1 - 2 Switch(config-if)#switchport mode access Switch(config-if)#Switchport access vlan 50 Switch(config-if)#switchport voice vlan 10 As stated by Morten via IRC this has not been implemented yet also due to the fact that they lack the devices to test on. I wanted to ask if it was possible to implement this so it becomes part of the main NAV tree. We could fund this development and help with the testing. Maybe you could also give an estimate on how much work this would be? Thanks in advance, Mischa -- Mischa Diehm | Network Team (NINS) UniBasel | IT-Services (ITS) Klingebergstr. 70 | CH-4056 Basel Tel. +41 61 267 1574 | https://its.unibas.ch

Typeoid issues
by ken.livesey＠gmail.com 29 Sep '15

29 Sep '15

So I am using the latest appliance in a vmware environment and I am new to NAV as of two weeks ago. Things started well and I am in love the potential of NAV. I had 20 devices added and those were working well; however I have run into an issue that I cannot seem to wrap my head around. It stated last week when I added a device and it failed to locate the typeoid string after performing an inventory. As I added additional devices I kept getting the same results. Thinking it might be a resource issue I purged all devices, restarted NAV and just added the device where the typeoid string first failed to load. No change. I then started searching the web for other with like errors. Not much except for a singe bridge plugin error which does not match this issue. I then bumped up the logging for ipdevpol plugings and found this warning: [WARNING plugins.typeoid.typeoid] [inventory DA13_SW07.xxxx.xxx] Netbox has changed type from unknown to unknown (sysObjectID 1.3.6.1.4.1.9.1.367) Each device for where the typeoid failed to load has this warning. So I figure the typeoid just failed to populate the table correctly. So I matched the reporting sysObjectID with the correct Cisco name and created a database seed with this type. I then rescanned and bingo the type field populated. Thinking I was out of the woods I check after the next inventory poll and found the device failed to access the devices inventory. Huh. Logs report this issue: [ERROR jobs.jobhandler] [inventory DA13_SW07.xxxx.xxx] Job 'inventory' for DA13_SW07.xxxx.xxx aborted: Plugin ciscovlan reported a timeout I have verified the system snmp and switch configurations and they are identical. I am using snmp 2c and the same RO community for all switches. There are layer 2 and layer 3 switches with produce this issue. There multiple models and port configurations. These are single function LANS connected with high speed MPLS, broadband, and direct fiber connections. I am guessing this is all stemming from a condition where the device cannot be polled or cannot be polled in a allotted time. There are no network error to these site and I have some sites were devices work well and others do not. All other aspects of the device can be polled and reported on just fine it’s just the inventory which fails. Here is the snmp stats from a L3 device which is subject to this issue.

NAV RAM Usage
by Studart UNI-RN 29 Jul '15

29 Jul '15

Hello guys, I'm running NAV 4.2 in a production environment here at the company I'm working for. I'm using Debian Wheezy (no graph interface installed) with 1GB of RAM and I have about 50 devices in the NAV seed database. I've noticed that almost all the the memory is already in use. It's no problem for me to increase it since it's in a virtual environment. But since I increase it I was just wondering if this is normal for NAV to use such amount of RAM memory. Thank you very much, -- Studart Tavares Analista de Redes Liga de Ensino do RN UNIRN - Centro Universitário do RN 55 84 3215-2917 (r 2818)

Some beginners questions
by Per Andersson 26 Jun '15

26 Jun '15

Hello! I have just started trying NAV, and is running it on a small part of our network at the moment, and have some questions: It finds our vlans and matches them with the correct prefixes but since we don't follow the convention for naming router interfaces the net ident and description fields is either empty (most common) or a bit confusing. Is there a way to edit them manually (directly in the database?)? Any other suggestions? If I want to enter cabling, in which "direction" is it supposed to be, should I enter the wiring closet as "Room" and the office as "Target" or the other way around? /Per Andersson Chalmers IT-department

Django and Debian 8
by stutavares＠unirn.edu.br 08 Jun '15

08 Jun '15

Hi guys, I have a newly installed version of Debian Jessie and it doesn't install nav with the simple 'apt-get install nav'. One of the reason is the dependancy on Django, which is in version 1.7 in the packages repository. I read a post that says you are still working on this compatibility issue. Meanwhile what should I do? Wait for a new version of nav? Try and install an older verion of Debian? What are my options now to install a new nav in my network? All the best, Studart

NAV and VLAN with Virtualized firewall
by Mattias Söderholm 13 Apr '15

13 Apr '15

Hi! I have a problem with VLAN auto discover. I have followed the guidelines with adding the router (firewall), but it won't get the VLAN info from it. The firewall is a software firewall (Sophos UTM) that's running in a Hyper-V cluster for HA . Could it be the software switch in the Hyper-V that's giving some problem or the firewall software? Before I also had some HP 2530 swithes added as an GWS. Then I got some VLAN info added to NAV, but NAV deletes the VLAN info in the SeedDB after a while and create it again with a new ID. So now I have changed the HP 2530 switches back to SW and hope the VLAN info will stay in SeedDB! But it would be great if I can get VLAN info to show up in Netmap. Is there some way to fix this if I can't get the info from the firewall? There is also a problem if you change a GWS to a SW, then ipdevpoll try to still collect ip2mac from the device but won't get the info and you end up with WatchDog reporting problems with ip2mac for that switch, The solution I have used is to go into the database and delete all post related to ip2mac for that device from ipdevpoll_log_job table. Is it a bug or am I doing something wrong here? Best regards Mattias

NAV mac-search with Nexus and FabricPath

Hi, we have FP activated in our datacenter and use Cisco Nexus (5,6,7)k. I'm not sure what caused the problem but NAV can't find MAC-addresses on these devices and even on catalysts behind them anymore. I don't know what algorithm is used to figure out where a MAC-address is attached but maybe someone who knows can clarify what is needed for that to work?

I will assume this means you are using a stable version of Debian GNU/Linux as your OS. Is this a virtual machine? 10GB sounds awfully small compared to most modern physical drives, even looking two years back - I would not run NAV in production on such a small drive. Just the OS itself would take up a large chunk of those 10GB, so I would strongly suggest that you increase the drive size. > Not entirely sure what has filled the disk, but the ARP/CAM tables > would make sense.

Use the `du` command to figure out where in the directory structure the disk space is being used: du -csh /* | sort -h To see how much space PostgreSQL takes up, run: du -csh /var/lib/postgresql > Any help you could offer in clearing these down after a specific > number of days has elapsed would be appreciated. Once PostgreSQL is taking up X amount of space, it doesn't help to delete records to help the OS reclaim that space. The unused space is still allocated to PostgreSQL, which will re-use it when it needs to. After deleting a bunch of records, a full vacuum (with downtime) of the database must usually be issued to let the OS reclaim the disk space: sudo -u postgres vacuumdb --full See http://www.postgresql.org/docs/9.1/static/sql-vacuum.html . Regular record deletion will, of course, help maintain the database at a reasonable size. NAV comes with the navclean command, which can delete old log records from NAV's database. See /usr/lib/nav/navclean.py -h for more details. If the default expiry limit of 6 months is OK for you, you could set up a daily cron job to run something like this: /usr/lib/nav/navclean.py -f --arp --cam > Thanks > > Ally Haha, apologies for the Mr. Anderson quip; With no first name to go by, I just couldn't resist a reference to the Matrix ;-) -- Morten Brekkevold UNINETT

Hard Disk Full

Hi As an inexperienced NAV user - I need some assistance. Our instance of NAV has filled the hard disk and I wondered if there was a way to delete some records from it. I would also like to know if there was a way of limiting how much information was stored. Thanks

Cisco IOS 3.6.x / VTP
by kentobias＠wcn.co 25 Mar '15

25 Mar '15

Hello all, Great work on NAV, appreciate all the hard work. I've looked through the documentation and searched the archive and I haven't seen this issue. I can't seem to pin down the cause. NAV version is 4.1.2 on the Debian virtual appliance you offer. I've added a new group of Cisco 3850s to a network and now changes to port information aren't saved. Description information is not saved at all. VLAN information is changed, but only ephemerally, not in the actual port configuration. This means that the VLAN information isn't preserved across reloads. The only difference that I can find are the IOS version and VTP. The previous 3850s are running 3.3.x and the new 3850s are running 3.6.1. The new 3850s are using VTP v3 whereas the current 3850s are not. There are no error messages generated during the port configuration that I can find. Has anyone seen this before? Thanks.

Hi all I'm using NAV in an Italian Hospital, where all networking switches are from Enterasys (now Extreme Networks). Regarding the following interface counters: ifInMulticastPkts ifInBroadcastPkts ifOutMulticastPkts ifOutBroadcastPkts is it possible to add the graphs of the above counters on switch port details ? At the moment I have traffic, unicast, errors and discarded. Thanks Alex

How to speed up Geomap?
by Ingeborg Hellemo 04 Des '14

04 Des '14

The transition from NAV 3.15 to 4.X has made Geomap incredibly slow. If I change zoom-level it takes several (four) minutes before new dots and lines show up. I guess this has to do with graphite's webserver not being able to deliver data fast enough (5000 lines of "POST /render/ HTTP/1.1" 200 XXX "-" "Python-urllib/2.7" in httpd-access.log) . The httpd process runs at 100% WCPU Is there something I can tune to make Geomap usable again? --Ingeborg -- Ingeborg Østrem Hellemo -- ingeborg.hellemo(a)uit.no Dep. of Information Technology --- Univ. of Tromsø

Additional SNMP Polling through NAV
by jch＠raytheon.com 14 Nov '14

14 Nov '14

I am really new to NAV, but I've liked it so far in my lab testing. I do have some routers whose CPU utilization is not showing up, and I would like to poll some non-standard OIDs (like IP SLA metrics) even if NAV won't display them. I could use graphite to do that for me separately, but utilize the engine that NAV provides. Could someone point me to where I might need to go to do that? Is there an OID somewhere that could be added or updated to support newer router CPU metrics, so that my Cisco ISR-G2 routers will have that displayed? How can I customize the polling of some devices (mostly Cisco routers) to get additional metrics? I have not found where I can modify or add scripts to do this and need some general pointers on where to look on the internet as well as on the system. Since this is just a lab environment, I have all the NAV components on one server. Thanks, Joel

SNMP agent down
by Steve Kersley 13 Okt '14

13 Okt '14

I'm trying out the NAV virtual appliance (4.1.0), talking to 25 or so Cisco switches. It was working fine but after a few weeks, one of the switches is showing a problem, "SNMP agent down". The SNMP agent is not down. The switch is fine, its configuration hasn't changed. I can talk SNMP to it fine using the same credentials from other machines, and the NAV VM can talk SNMP fine to all of the other switches - all have the same SNMP credentials, and most are the same model of Cisco switch. (I was going to test from the NAV VM or watch the network traffic but the appliance doesn't come with the snmp tools or tcpdump, and is isolated from the Internet so not easily able to install them) Restarting the switch made no difference. I've had a rummage in the logs without seeing anything obvious. Any clues where to look to find why NAV is unable to talk SNMP to this one switch suddenly, after working fine for several weeks?

Unmanaged switches
by pentium100＠gmail.com 13 Okt '14

13 Okt '14

Hello, Is there a way to insert an unmanaged switch to the network map? I use some of them in my network and would like to mark them on the map. Right now I have real network topology something like this: Router -- managed switch -- unmanaged switch -- devices Only one devices on the unmanaged switch is shown, even though multiple MACs are detected on the relevant port of the managed switch. Is there a way to mark that there is an unmanaged switch so that those devices are drawn on the map (with link speed/usage pulled from the devices if possible)?

Mobile routers in NAV
by Sigurd Mytting 26 Sep '14

26 Sep '14

Hi! I will be deploying about 100 mobile routers in cars the next six months, they will be offline whenever the car is moving and out of cellular coverage and when the car is not in use by our roadside people. These routers will be in a closed VPN/APN from our teleprovider so I have full access and controll whenever they are online. I'm wondering how to add these to NAV; I really don't care if they are down and preferably they should not show up as such under "Status". I would like statistics whenever they are online (not to mention the mac-adresses connected, possibly also a few other more specialized metrics like cell signal and so on). If it matters; we'll be using Cisco hardened 819 routers with an integrated WiFi access point. Anyone having any pointers to how I should manage them in NAV? Cheers, -Sigurd

White spaces in graphs
by Sigurd Mytting 26 Sep '14

26 Sep '14

Hi, my graphs are getting white spaces and I'm trying to tune ipdevpolld: Running with no tuning at all about 80% of the graph is white on every port/device. If I restart ipdevpolld manually with -m most of my graphs are ok, occasionally I get white spaces, lets say around 1-2% of the last day. First of all, is there a way to run ipdevpolld with multiprocess without doing a manual start of the process? (I would expect something in /etc/default/nav.) Besides running multiprocess, what else is usefull? I've tried incereasing max-repetitions without much luck. I do have some timeout issues on satellite links so I've increased this to 4.5. I initially thought this was a graphite problem, but I've heavilly tuned my graphite-host and there seems to be no problems there, running carbon-relay and four carbon-cache and from what I can gather they are not hit hard at all. I have about 46k ports and 1500 devices, one dedicated server for graphite, one for postgresql and one for gui, ipdevpolld and other nav processes. Any hints? Cheers, -Sigurd

BUT *another.host* is physically connected in switch port 1/2 of 252.121, as reported bellow: [image: Imagem inline 3] AFAIK, Nav will use LLDP over CAM to build the network topology. But, in this case, maybe is occurring something wrong, because seems that Nav isn't collecting LLDP informations from switches to build the network topology. Another strange thing is the UNRECOGNIZED NEIGHBORS report. It is reporting that 251.245 is an unrecognized neighbor of 252.121 with lldp as source. Why??

Sysname () is already in database
by jorr＠streamguys.com 13 Aug '14

13 Aug '14

Hello, I am demoing out the NAV appliance and we have a number of physical and virtual hosts that do not have reverse DNS entries available, resolution of the IPs belonging to the hosts results in unknown.domainname.tld. When attempting to add multiple hosts to the NAV seed database, I receive errors when NAV attempts to resolve the DNS name of the host, claiming that the host already exists, despite all unique information with the exception of the failed resolution of the fqdn. Is there a work-around so that NAV does not lookup the DNS name of said devices? Sincerely, Jesse

If the LLDP neighbors were unidentifiable on the first run, but have become identifiable at a later time, this will not be rectified by NAV until this device changes this timestamp and causes NAV to process it again. If you search for the MAC addreses using the Machine Tracker and interface reports, as I asked, and found the MAC addresses to be identifiable, you may be able to kickstart a new processing of the LLDP information by deleting NAV's stored timestamps. Something like this would do it: sudo -u postgres psql nav \ -c "DELETE FROM netboxinfo WHERE key='poll_times' AND var='lldp'" It may be a better strategy for NAV here to invalidate these timestamps on set intervals to force reprocessing of the LLDP information; just not on every run of the LLDP collector. -- Morten Brekkevold UNINETT

NAV 4 hardware/installation recommendation
by Sigurd Mytting 02 Jul '14

02 Jul '14

Hi all! I'm looking into doing an upgrade of our NAV installation, we're on 3.15 and it's time to move on to 4. I'm looking for advice on hardware setup, filesystem layouts and so on. Currently we have about 1500 devices, 99% routers and switches, in the database (mostly Catalysts ranging from 2940 to 3750, a few 6500 and Nexus 7k/5k, Juniper SRX/EX and a Juniper QFX, around 50 virtual Cisco ASA contexts as well). Hardware is a single server, 2x dual core opteron 2.6GHz, 32GB ram and several raid1's (in hardware). I've put postgres on its own 15k RPM raid1, the same with /var/lib/nav and confined /var/log/nav to the OS-drives with its own partition. I have been and will be using the excellent debian-packages from UNINETT for my installation. I've done some tricks for optimizing disk performance, by using the "noop" disk scheduler I see a big difference in system sluggishness, even when I have loads around 30. This is mostly related to my hardware raid, the default debian scheduler does not give a good performance when operating on a hardware raid (same thing with SSDs). I'm planning a new installation, this time on two servers, but I have yet to determine disk and raid layouts and what to put on each server. Postgres away from the collector is rather given, I'm unfamiliar with graphite, could/should it be put on another server? (I might find a third server if its recommended.) What will be the default datastores be? I'd like to set up separate partitions before installing the NAV-packages to make sure filesystems like /var don't run out of space when NAV logs grow, postgres goes wild and/or graphite stores what I'm actually asking it to store... What will typically be hit hard with random IO, sequential read/write and so on? Any input would be apreciated. Cheers, -Sigurd

Announcement: NAV 4.1.0 released
by Morten Brekkevold 26 Jun '14

26 Jun '14

The feature release of the new NAV 4.1 series is now available. The source code is available for download at Launchpad [1]. A new package for Debian Wheezy has _not yet_ been published in our APT repository [2], but will be sometime tomorrow, Friday. Changes ======= The following new features and changes have been introduced: * LP#744951 (show % usage for smaller subnets in subnet matrix) * LP#1062298 (Watchdog feature to monitor internal status of NAV processes) * LP#1169557 (Room and Organization opt fields should be replaced with an arbitrary variable=value scheme) * LP#1248092 (ipdevpoll CAM collection optimizations) * LP#1319657 (ipdevinfo alert tab does not display alerttype) * LP#1312648 (Remember user's preference for number of rows per page in SeedDB list views) * LP#1311205 (Change administrative status of interface from PortAdmin) * LP#1334243 (REST API) Please refer to the release notes [3] for further information on upgrading. Because the 3.15 and 4.0 series have been maintained in parallel with the 4.1 development line, you may need to use the -o option if you are executing the `navsyncdb` program manually for schema upgrades. Also, as the release notes describe, `navsyncdb` will need postgres superuser access to install the required `hstore` extension. Happy NAVing everyone!

The third maintenance release of the NAV 4.0 series is now available, version 4.0.3. The source code is available for download at Launchpad [1] and a new package for Debian Wheezy has been published in our APT repository [2]. Changes ======= The following reported bugs have been fixed: * LP#1255978 (Add Arnold-information in ipdevinfo Port Details) * LP#1301191 (Portadmin vlan change for many interfaces takes a long time) * LP#1318534 (Publish timestamps is set to Default when editing a Message) * LP#1321246 (vlan search result should be sorted by vlan) * LP#1321251 (search for Netbios in Machine Tracker widget) * LP#1321634 (Some alerts are never resolved when devices have moved around) * LP#1323206 (device history-link in ipdevinfo not working as intended) * LP#1324108 (arnold fails to manually detain when sysname is uppercase) * LP#1327098 (ipdevpoll jobs are marked as successful when nothing was done) * LP#1333167 (Netbox.up sometimes out of sync with actual alert-based box state) * LP#1334258 (Geomap fails to load any data if a single Graphite metric causes an error) Because the 3.15 and 4.0 series have been maintained in parallel, you may need to use the -o option if you are executing the `navsyncdb` program manually for schema upgrades.

Graphite connection issues
by Ukeme Noah 06 Jun '14

06 Jun '14

Greetings Everyone, I recently installed NAV 4.0.2 on Debian (by compiling) using instructions from https://nav.uninett.no/doc/latest/intro/install.html All dependencies were installed successfully. Python modules were installed using PIP. Graphite and Carbon appear to be installed and working as well (at this point, I launch carbon and graphite using the scripts " carbon-cache.ph" and "run-graphite-devel-server.py" located in "/opt/graphite/bin". Access to NAV (as well as Graphite's) main page over a web browser present no issues however, Availability under Status reads "Graphite unreachable". In addition, the Graphite web interface presents entries for Carbon and none for NAV. I am lead to believe that the carbon backend is working given the contents of the folder "/var/lib/graphite/whisper/nav" includes entries for NAV seeded devices. On that note, any assistance/suggestions that could lead to resolving this issue would greatly be appreciated. I can provide additional information where required. Thanks, Ukeme

The second maintenance release of the NAV 4.0 series is now available, version 4.0.2. The source code is available for download at Launchpad [1] and a new package for Debian Wheezy has been published in our APT repository [2]. Changes ======= The following reported bugs have been fixed: * LP#1302403 (Unplugged HP power supplies are marked with "unknown" state) * LP#1303804 (No graphs are rendered if graphite base url doesn't end with a slash) * LP#1304279 (values in threshold alerts are always 100) * LP#1304455 (Submitting an empty search form crashes Arnold) * LP#1314503 (migrate_to_whisper.py crashes on mismatches between RRD files and database) * LP#1316091 (pping dies when carbon is unavailable) * LP#1316600 (external tools have no icons) * LP#1316965 (NAV 4.0 collects port traffic stats from EDGE devices) Because the 3.15 and 4.0 series are maintained in parallel, you may need to use the -o option if you are executing the `navsyncdb` program manually for schema upgrades.

Integration with GIS
by Corey Thompson 09 Mai '14

09 Mai '14

Before I start doing such, I'm wondering if anyone has done any integration between NAV and a PostGIS based GIS system (mostly using QGIS for "frontend"), as I would rather add to existing work rather than repeating it...I thinking of just creating views in postgres referencing NAV data for the GIS to use to retrieve device inventory, status, and statistics in spatial queries. If it becomes successful and useful, I will do a writeup. -- Corey Thompson Technology Manager East Grand Forks Water and Light 1010 5th Avenue Northeast East Grand Forks, Minnesota 56721 218-399-3310 direct cthompson(a)egf.mn

Manually adjust topology - [interface] table changes
by davide＠wpweb.com 09 Mai '14

09 Mai '14

I read https://nav.uninett.no/doc/3.15/howto/debugging-topology.html but I can't resolve the error in topology discovering on my network. I have some Catalyst 3550 with stackable modules that automaticaly are not correclty connected. I changed the [interface] table to adjust my topology and all is okay but my changes are lost from automatic discover. How can I permanently change the [interface] table? Thank you NAV 4.0.1

Setting up NAV from scratch/non-OVA (Graphite-issues)
by Joachim Tingvold 29 Apr '14

29 Apr '14

Hi, Decided to install NAV from 'scratch' (i.e. not use the OVA-package). Got NAV running fine, but had some hiccups getting Graphite working as it should. Found no documentation on this what-so-ever (neither on the NAV-pages, or the Graphite-pages), so had to try-and-fail some. Thought I'd share. - Debian Wheezy (not OVA) - NAV via apt (from https://nav.uninett.no/debian) root@tardis:~# dpkg -s nav|grep Vers Version: 4.0.1-3 1) Fixed /etc/nav/graphite.conf; base=http://localhost:8888/ 2) Copied content of '/usr/share/graphite-web/apache2-graphite.conf' into own VHost; <VirtualHost localhost:8888> ( + add NameVirtualHost + Listen in /etc/apache2/ports.conf) 3) Set 'CARBON_CACHE_ENABLED=true' in '/etc/default/graphite-carbon' Set 'ENABLE_UDP_LISTENER = True' in '/etc/carbon/carbon.conf' Set 'SECRET_KEY = <longsecretstring>' in '/etc/graphite/local_settings.py' Set 'TIME_ZONE = '<Gallifrey>' in '/etc/graphite/local_settings.py' 4) cd /usr/share/pyshared/graphite python manage.py syncdb 5) Started carbon-cache (/etc/init.d/carbon-cache start) 6) Started NAV + apache Should work. Some of the errors I got along the road; <http://files.jocke.no/b/nav-graphite-error.txt>. -- Joachim
