Migration to new NAV version
by Mischa Diehm 05 Mar '14

05 Mar '14

Hi, we migrated our installation to a new HW and Debian stable (3.14.15-1 -> 3.15.5-1). I got all dump.py data migrated without problems. Now we got a lot of User Accounts and Groups with a lot of different Privilidges attached to them. Is there also a (painless) way of transforming this data into the new installation? 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

Hardware recommendation
by Mischa Diehm 05 Mar '14

05 Mar '14

Hi, first of all welcome to the list! we (UniBasel) use NAV for quite some while now and are very pleased with the possibilities NAV gives us. We use Debian as OS with the following Setup: root@urz-nav:~# uname -a Linux urz-nav 2.6.32-5-amd64 #1 SMP Fri May 10 09:44:53 UTC 2013 x86_64 GNU/Linux root@urz-nav:~# cat /etc/debian_version 6.0.7 root@urz-nav:~# dpkg -l | grep nav ii nav 2+3.14.15-1 Network Administration Visualized A problem we have since a while is that our system is permanently under a lot of load (mostly CPU bound) and we haven't really found a way to reduce the pressure. The hardware we use is a hp blade (ProLiant BL460c G6) with: Intel(r) Xeon(r) Processor X5550 (4 Cores/ 8 Threats) (8M Cache, 2.66 GHz, 6.40 GT/s Intel(r) QPI) and: root@urz-nav:~# free total used free shared buffers cached Mem: 12321700 11673596 648104 0 387768 9123748 At the moment we have 1460 active Devices (mainly Cisco Switches). Around 30 or 40 are OVERDUE in: https://urz-nav/report/lastupdated So my question is, do you have any good experience with HW-systems that are actually dealing with this amount of devices or is there any tuning possibility (without losing functionality) we could try to reduce the pressure on the system?

Announcement: NAV 4.0 beta 3 released
by Morten Brekkevold 06 Feb '14

06 Feb '14

The third beta release of the NAV 4.0 series is now available for download at Launchpad: https://launchpad.net/nav/4.0/4.0b3 I'm also happy to report that the Norwegian University of Science and Technology and the University of Agder have both signed on as beta testers using the virtual appliance. Here's the changelog summary of today's release: Bugfixes: * LP#1270095 (APC sensors stored at wrong precision) * All VLAN utilization graphs produced error messages in b2. User-visible features and improvements: * Inserted the new NAV logo, and completely reworked the page footer. * New NAV blog feed widget added as default. * UI clean-ups and improvements in front page widgets, login page, Geomap, SeedDB, Messages, PortAdmin, Radius, Syslog Analyzer, IP Device Info, room photo database, personal preferences page and others. * Fixed Internet Explorer 9 brokenness. * Tool descriptions have been completely re-authored, and are now also available as a subheading inside each tool. A Debian package has been uploaded to our APT repository. We have not yet built a new virtual appliance, but you can upgrading your existing one using the regular apt-get route. The updated package introduces a dependency to `python-feedparser`, so you may need to either use 'apt-get dist-upgrade' or 'apt-get install nav' to force an upgrade of the nav package (after issuing 'apt-get update', of course). As usual, please report bugs at https://launchpad.net/nav/+filebug . Happy NAVing everyone! -- Morten Brekkevold UNINETT AS

The NAV Blog
by Morten Brekkevold 22 Jan '14

22 Jan '14

Hi all, we thought we should do as everybody else on the Internet, so this week we launched our own NAV blog. As NAV developers, we hope to blog about what we're working on behind the scenes, be it either related to network management or software development, but it will always be related to our work on NAV. Our first entry is up on http://blog.nav.uninett.no/ - have a read :-) -- Morten Brekkevold UNINETT

Announcement: NAV 4.0 beta 2 released
by Morten Brekkevold 09 Jan '14

09 Jan '14

The second beta release of the NAV 4.0 series is now available for download at Launchpad: https://launchpad.net/nav/4.0/4.0b2 This release fixes three bugs reported against the first beta version, as well as improving the UI of several of the tools: * LP#1262644 (seeddb bulk import does not work) * LP#1263040 (ipdevinfo should not crash when Graphite-web is not reachable) * LP#1267464 (NAV 4 must provide a tool for migrating RRD data from NAV 3) The most important of these changes is the addition of the conversion tool to migrate data from NAV 3's RRD files into NAV 4's Graphite metrics. This was held back from b1 due to license compatibility issues, which should now be resolved. Instructions for migrating RRD data has been added to the release notes, but in short, they refer to the migration guide available at [1]. A Debian package has been uploaded to our APT repository. We have not yet built a new virtual appliance, but upgrading your existing one should be simple matter of "apt-get update && apt-get upgrade". As usual, please report bugs at https://launchpad.net/nav/+filebug . Happy NAVing everyone! [1] https://nav.uninett.no/doc/4.0/howto/migrate-rrd-to-graphite.html -- Morten Brekkevold UNINETT AS
