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

Is there a way to change the default 10 rows in the lists?
by davide＠wpweb.com 23 Apr '14

23 Apr '14

It should be useful if I can change the default 10 rows in the "Show xx entries" in the lists. I searched through the configuration file and in the .js but I can't change this. I wish to put 50 rows or at least "all". Thank you

Problem with uplink detecion
by Martin.Jaburek＠cah.cz 22 Apr '14

22 Apr '14

Hi, I just face another problém with uplink detection. I tried to follow documentation about troubleshooting topology, but it yielded no results. I check switchport report of both connected devices and there it is showed in the columnt labeled as connected to. I also check cdp and it also report it correctly. I also found another problém when it displays an actual uplink, but with empty from device (which seems to me quite strange). In other case an uplink is showed only on one device but not the other. Is there any limit about number of uplinks? (I have more then ten uplinks on one box) Brgds Mat -----Original Message----- From: nav-users-request(a)uninett.no [mailto:nav-users-request@uninett.no] On Behalf Of Morten Brekkevold Sent: Thursday, March 27, 2014 3:09 PM To: nav-users(a)uninett.no Subject: Announcement: NAV 3.15.7 released For those of you who wish to continue running NAV 3.15 for while, the seventh maintenance release of this series is now available for download at Launchpad: https://launchpad.net/nav/3.15/3.15.7 This release fixes 12 reported issues: * LP#1251211 (portadmin wishlist: option to reset active interface whene changing vlan) * LP#1285601 (Switch ports on non-existant VLANs on Cisco switches don't appear as switch ports in NAV) * LP#1287700 (SeedDB will readily accept serial numbers with trailing spaces) * LP#1289219 (affected displays no information on nodes not in topology) * LP#1289320 (Submitting invalid alert subscription forms cause crash instead of error message) * LP#1291956 (LDAP auth against MS AD broken since NAV 3.14.1592653) * LP#1291978 (User supplied login name is not escaped in LDAP search filters, causing possible injection vulnerabilities) * LP#1292513 (sysname/reverse dns lookups are inconsistent or lacking after a bulk import) * LP#1293621 (missing cascade in table accounttool) * LP#1295092 (Only modules and power supplies on first member are collected from stacked HP 2920) * LP#1297200 (powersupplywatch crashes when there are more than ~1024 devices to poll) * LP#1297767 (Django exposes sensitive data like: username/password) Please report further bugs at https://launchpad.net/nav/+filebug A binary package for Debian Wheezy has been made available in our APT repository, as usual.

Problem retrieving port statistics
by Martin.Jaburek＠cah.cz 10 Apr '14

10 Apr '14

Hi, After recreating whisper databases I can see some of the graphs. Now I have another problém - not all statistics are collected! I checked graphite and it displays only few of them. The nav systém have ran for a day now, so I would expect, that it is enough time to collect all informations. In the screenshot (made from graphite webinterface) you can see various collected statistics - they are not even the same for various ports. There are no problems reported for this device in the ipdevpoll.log Any ideas?

We think this may be related to this bug: https://bugs.launchpad.net/nav/+bug/1292513 . This has been fixed and will be part of the next release. The port statistics are probably being stored using the IP-address not the DNS name of the IP Device.
