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?

Start automatically NAV services
by Orzakiewicz Cedric 20 Dec '13

20 Dec '13

Hi, Some NAV services don't start automatically (like "ipdevpoll") when my NAV server starts. I have to do it manually with the command "nav start ipdevpoll", and so on for each service not started. Do you know how can I make them start automatically ? Thank you very much :) Cédric.

New repository for the NAV Debian package
by Morten Brekkevold 30 Oct '13

30 Oct '13

As some of you may already have read, Werner is stepping down as the official maintainer of the NAV Debian package, mainly due to time constraints. UNINETT uses these packages in production, so as a result, I've taken over as package maintainer on behalf of UNINETT, and I will be building on the already awesome work Werner has put in. As of today, we've published our own APT repository for the packages we build. Instructions for using the repository can be found on the NAV wiki, at [1] . For those interested in the package sources, everything is version controlled and published on Bitbucket, at [2]. I've also enabled the issue tracker for that repository, so that any problems with the package itself can be reported there. Happy NAVing, everyone!

Announcement: NAV 3.15.0 released
by Morten Brekkevold 17 Oct '13

17 Oct '13

The initial release of the new NAV 3.15 series is now available for download at Launchpad: https://launchpad.net/nav/3.15/3.15.0 This feature release brings many changes to NAV, including, but not limited to: * mod_python is no longer required; mod_wsgi is the new recommended way to deploy the NAV web interface. * Devices' conceptual layering of interfaces is now collected and presented in ipdevinfo. This enables you to, among other things, see which physical ports comprise a port- or etherchannel. Some vendors also use this to show which physical switch-ports are forwarding packets to/from a given VLAN interface. * The Netmap tool has been redesigned and re-engineered. Multiple improvements have been made based on user feedback. * The Netmap contents can now be exported/downloaded as an SVG file, but this feature is currently only supported by the Google Chrome browser. * Multiple parallel links are now indicated by the Netmap by two parallel black markers drawn across the link in question. Details of the underlying links are are now properly displayed when clicking on the link line. * Interactive next-hop neighbor map in new ipdevinfo tab. * "What-if" analysis in new ipdevinfo tab displays devices and organizations that may be affected if the selected device goes down. Based on NAV's topology information. * Images with descriptions can be uploaded and attached to rooms. Useful for, among other things, photo-documenting the contents of wiring closets. * Subcategories have been replaced by cross-category device groups. Arbitrary selections of IP devices can be organized into device groups. * Potentially out-of-date CAM and ARP records are highlighted in Machine Tracker search results. * Community strings are censored in SeedDB IP Device listing. * New program enables streamlined dumping and reloading, with optional filtering, of the NAV PostgreSQL database. This simplifies beta testing of new NAV versions by copying the production database to a test server. * 26 more metrics from APC UPS devices are now collected and graphed. Fixes for various reported bugs: * LP#1055383 (netmap saves a new view when it should update view) * LP#1057423 (netmap algorithm indicator turns red when clicking on something in left bar) * LP#1062203 (ipdevpoll job configuration description) * LP#1165039 (Selecting a datasource for bulk threshold config intermittently fails with "internal server error") * LP#1169926 (Replace mod_python with Django/WSGI) * LP#1213818 (LDAP authentication crashes on non-ASCII usernames and/or passwords) * LP#1222666 ("Uptime" in ipdevinfo never resets) There are also various dependency changes, documented in the release notes. Please report bugs at https://launchpad.net/nav/+filebug Binary packages for Debian will be made available as soon as possible. The Debian package is maintained by Morten Werner Forsbring, on commission from UNINETT. Happy NAVing everyone! -- Morten Brekkevold UNINETT AS

Announcement: NAV 3.15.1 released
by Morten Brekkevold 17 Oct '13

17 Oct '13

The first maintenance release of the NAV 3.15 series is now available for download at Launchpad: https://launchpad.net/nav/3.15/3.15.1 This release fixes the following reported bugs: * LP#1230240 (navsyncdb command is not installed in NAV 3.15.0) * LP#1230299 (Cricket+NAV 3.15.0 may not work under Django 1.4.5) * LP#1235355 (Machine Tracker performs unnecessary join on netbios table) * LP#1235356 (The netbios table needs an index for efficient joins on the arp table) * LP#1236753 (machinetracker netbios search crashes) * LP#1236813 (Alertengine crashes on nav version 3.14) * LP#1239139 (Weathergoose2 GOOSENAME not initialized in snmptrap handler) * LP#1240855 (Mac search + DNS crashes with TypeError in NAV 3.15.0) It seems we also forgot to mention a new feature when 3.15.0 was announced: The ability to set a room's geolocation coordinate via an interactive map in SeedDB. Please report bugs at https://launchpad.net/nav/+filebug Morten Werner Forsbring will be stepping down as maintainer of the Debian package, which is also the reason that no official package has been announced for the 3.15.0 release. For those of you already following Werner's repository at http://pkg-nav.alioth.debian.org, the wheezy-test archive there does contain a 3.15.0 package, built in cooperation between Werner and myself. As we are using the Debian package in production at UNINETT, we will be maintaining and releasing the Debian package ourselves in the future. More details will be announced shortly. Thank you, Werner, for all the work you have put into creating and maintaining the Debian package thus far! Happy NAVing everyone! -- Morten Brekkevold UNINETT AS

snmp v3
by Klaus Vink Slott 07 Oct '13

07 Oct '13

Hello list I am currently looking for at a snmp based monitoring system and was asked to consider nav as a candidate. I have downloaded and startet the virtual app, but before I am putting to much effort in configuring and testing I wonder if SNMP v3 is supported? This is a requirement for our install but I cant find any mention on the webpages. -- Regards Klaus

Increase rommid column size table room
by Bruno Galindro da Costa 02 Oct '13

02 Oct '13

Morten, I need to add a roomid that has more than 30 chars. I've altered the size of rommid column in table room (at database level), but the HTML fields has a 30 chars limitation. Nav web has built on Django framework which is very nice ;), but I don't know where I can make this modification. *** EXPLANATION: Here at UFSC, we have devices in many places. Bellow has an example of devices physical location: UFSC (Santa Catarina's Federal University) Campus Trindade (City: Florianópolis - SC - Brazil) CCB (Biological's Science Centre) Morfologia (Morphology's Department) Secretaria da Morfologia (Morphology's Department Management Room) Lab. Virtual de Estudos Morfológicos (Virtual Laboratory of Morphological Studies) We have added UFSC as a Parent Organization for Campus Trindade (there are many other campus, but I try to focus only on Trindade): [image: Imagem inline 1] CCB (Biological's Science Centre) was registered as a location: [image: Imagem inline 2] All the other information we are try to register as a room. Here we are experiencing the mentioned limitation problems. We have thought to register these information as a Location, but the Location information isn't displayed at ip device info screen nor at Edit IP Device screen. Unfortunately, this complicates our work. Here is a simple room registry example: CCB_Morfologia_Lab. Virtual de Estudos Morfológicos:CCB::Contato - Gianor - 2320:Na Morfologia/Anatômico, passando a secretaria de morfologia, entre os anfiteatros:::-27.60106, -48.52385 If I try to split "CCB_Morfologia_Lab. Virtual de Estudos Morfológicos" into two fields: (rommid: CCB_Morfologia , description: Lab. Virtual de Estudos Morfológicos) this will cause a contraint violation, because I'll need to add another device that lives in Morphology's Department, but in another place (Morphology's Department Management Room for example). My sugestion is: 1 - add a field called Location in Edit IP Device screen which filters the Room field. 2 - add Location and Parent Organization information at IP Device Info. We can help you and your development team to make these modifications (and maybe others). This could be a nice starting. I hope you understand our necessity and help us to put NAV in production for replace Whatsup Gold. :) -- Att. Bruno Galindro da Costa
