Performance questions and weathermap
by Manuel Marín 08 Jul '24

08 Jul '24

Dear NAV community We are looking for a network monitoring platform as a replacement to cacti/weathermap and I was wondering if there is information about performance/hardware requirement for a network with ~20K networks devices. Can NAV support this number of devices? It would be great if someone can share their experiences running NAV with large networks. Thank you!

NAV - Palo Alto Plugin: MAC Records Keep Expiring
by Mehmet E. Şahin (BAŞKANLIK-BİDB) 06 Jun '24

06 Jun '24

Hi Everyone, We started using the new Palo Alto plugin with excitement. It successfully retrieves the ARP table from the Palo Alto firewall as XML every 20 minutes. However, for some reason, while reading the ARP table from Palo Alto, the records are constantly expiring and being added again. This does not occur for the ARP records received via SNMP. Has anyone observed this situation? In the example below, the IP address 192.168.0.250 belongs to a server. There is no disconnection, but for some reason, the MAC tracker records show that a re-connection is happening every 20 minutes. (BTW - our nav version is the latest (5.10.2).) Best Regards Mehmet E. ŞAHİN

Announcement: NAV 5.10.2 released
by Morten Brekkevold 03 Jun '24

03 Jun '24

The second maintenance release of the 5.10 series of NAV is now out! The source code is available for download at GitHub [1]. New packages for Debian 10 (Buster) and 11 (Bullseye) are available in our APT repository [2] as usual. We haven't started building packages for Debian 12 (Bookworm) yet, as NAV does not yet support running under Python 3.11. Do note that 5.10 is the **last series we will package for Debian 10** (not 11, as previous announcements read), as NAV 5.11 will drop support for Python versions older than 3.9. Please be extra aware of config file changes. Look out for `*.dpkg-dist` files in `/etc/nav` and make sure to update your running config. Changed ======= - snmptrapd renamed to navtrapd to avoid naming conflicts with Net-SNMP programs (#2926) Fixed ===== - Replace incorrect fix for premature ARP record closure introduced in 5.10.1 (#2910) Release notes ============= We always advise you to have a look at NAV's accompanying release notes [3] before upgrading. Happy NAVing everyone!

navtopology is already running
by Ingeborg Hellemo 21 May '24

21 May '24

NAV 5.9.1 Suddenly, since yesterday, a lot (but not all) of the navtopology cron jobs sends an email with "navtopology is already running" An example: /var/log/cron Apr 30 09:35:00 <hostname> /usr/sbin/cron[69867]: (navcron) CMD (navtopology --l2 --vlan) 10 minutes later an email arrives Date: Tue, 30 Apr 2024 09:43:35 +0200 (CEST) Subject: Cron <navcron@bjarne> navtopology --l2 --vlan navtopology is already running (69867) What can trigger this error? var/log/navtopology shows that the job runs as usual. (Last lines in the run is "deleting unused prefixes/vlans") The one thing that changed before this error turned up is that the server running NAV was moved behind Cisco ACI and a (application centric) firewall. --Ingeborg -- Ingeborg Østrem Hellemo -- ingeborg.hellemo(a)uit.no Dep. of Information Technology --- Univ. of Tromsø

Closing down our IRC channel
by Morten Brekkevold 13 May '24

13 May '24

Hi everyone! We regret to inform you all that we will be closing NAV's official IRC channel on Libera.Chat by the end of this week. The IRC channel has seen very little activity these last few years, and it's harder to have the younger engineers on our team engage in IRC as a community tool. It seems I'm the only one from our team hanging around the channel, so by "closing" we really mean that I will stop paying attention to the channel, and the navbot will be taken down. Given the activity level of the IRC channel, we don't think anyone will miss it much. Going forward, we encourage you to use the discussion boards on GitHub [1] as a replacement, or just keep using this mailing list :) [1] https://github.com/Uninett/nav/discussions -- Sincerely, Morten Brekkevold Sikt – Norwegian Agency for Shared Services in Education and Research
