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
by Mischa Diehm 09 Apr '15

09 Apr '15

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? Thanks in advance, Mischa -- Mischa Diehm | Network Operations Center (NOC) UniBasel | UniRechenZentrum (URZ) Klingebergstr. 70 | CH-4056 Basel Tel. +41 61 267 1574 | http://urz.unibas.ch

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

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.

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? Steve.

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

navsyncdb, hstore extension and superuser
by Ingeborg Hellemo 19 Sep '14

19 Sep '14

Trying to upgrade my database from 3.15 to 4.1.1. I see that the script tries to connect as user 'root' while "Creating hstore extension": Creating hstore extension in database nav psql: FATAL: no pg_hba.conf entry for host "129.242.5.180", user "root", database "nav", SSL off Failed to install the hstore extension, maybe you need to run as the postgres superuser? I can of course edit my pg_hba.conf but it will not help since my postgres superuser is 'pgsql' not 'root'. How can I make the script connect as user 'pgsql'? or Can I instead run some sql by hand? --Ingeborg

Switch inventory isn't updated
by Bruno Galindro da Costa 15 Aug '14

At http://nav.setic.ufsc.br/report/swport, I can view my interfaces with VLANs assignments. The problem is: the information for a given netbox isn't updated. All of the jobs are running fine for that netbox (green lights in jobs list). For example: I've a set of tagged VLANs in a trunk port on that switch that isn't reported by NAV. I'll sent to Morten DEBUG logs from ipdevpolld inventory job. -- Att. Bruno Galindro da Costa
