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.

Graphite on other machine
by Martin.Jaburek＠cah.cz 07 Apr '14

07 Apr '14

Hello, I tried to run graphite on another machine. I was able to redirect statistics collection, but I cannot see graph data: I have made changes in etc/graphite.conf: [carbon] # # NAV supports Carbon's UDP line receiver. Host and port information of # the backend can be configured in this section. # host = IP port = 2003 [graphiteweb] # # Where is the Graphite web interface located. NAV needs this to get graphs # and data from Graphite. # base=https://IP When I first started NAV, it was configured to use the graphite on the same machine as NAV. It worked. When I changed it and restarted NAV processes it sent statistics to the new IP (I confirmed it via graphite web fronted), but it still tries to access old graphiteweb for rendering graphs, not the one changed in grahpite.conf. Can there be a problém with certificate? (it is self signed one) Isn't it somehow cached in a database?

But I am still experiencing gaps on some graphs. There is one device which suffers from it most - see attached graphs. (graphs are from 2 devices - one OK and the other with GAPS) Gaps are only in port metrics graphs - they are at exactly the same time on all ports on given device. Systém metrics are just fine on this device. I checked the 5min graph of ipdevpoll systém metrics and it shows 100 at peak times, what I assume are only nearly 2 minutes. I'm monitoring about 140 devices right now with nav. I think that it is much correlated to my yesterday upgrade to 4.0.0 (from 4.0b5). Since then I can also see attached errors. They were not there when I was on version 4.0b5. It happens only on cisco catalyst 4500/6500 and one type of 3560E.

Which graphs have gaps? Port metrics? System metrics? All of them? How many devices are you monitoring, and what does the runtime of the various ipdevpoll jobs look like? If the 1minstats job is spending more than 1 minute to complete for any device, there may be gaps its graphs, 5 minutes for the 5minstats job. -- Morten Brekkevold UNINETT
