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?

The fourth beta release of the NAV 4.0 series is now available for download at Launchpad: https://launchpad.net/nav/4.0/4.0b4 Here's the changelog summary of today's release: User-visible features and improvements: * A port metrics tab has been added to IP Device Info, so that all port graphs are available on a single page (just like you're used to from Cricket). * Sub-tabs in IP Device Info are now hyperlinkable. * Portadmin UI has been reworked again, based on feedback from NTNU. * All users are now presented with a "NAV tour" widget on their front page, which will give an interactive tour of the functionality on the new front page. * Introduced widget for displaying the contents of `welcome-anonymous.txt` and `welcome-registered.txt`, as was always present on the NAV 3 front page. * Introduced button to add any graph displayed in NAV to your front page widget dashboard. * CPU stats from HP devices are now included in ranked CPU statistics. * New button in ranked statistics to switch between regular graph and pie chart. * Improved titles, legends and display of various graphs. * Removed obsolete Adobe Flash component that was used to facilitate CSV export of the room switch port view. A Debian package has been uploaded to our APT repository. We will likely build and upload a new version of the virtual appliance later today. As usual, please report bugs at https://launchpad.net/nav/+filebug . Happy beta-NAVing everyone! -- Morten Brekkevold UNINETT AS

The sixth maintenance release of the NAV 3.15 series is now available for download at Launchpad: https://launchpad.net/nav/3.15/3.15.6 This release fixes 3 reported issues: * LP#1274406 (Power Supply status is not correct) * LP#1278433 (Link to alert profiles permissions is missing) * LP#1279748 (Malformed timestamps cause internal crash in activeip API call, instead of proper error message) 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.

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
