Removing HP SwitchStack support from NAV
by Morten Brekkevold 17 Sep '08

17 Sep '08

Hi everyone, for quite some time we've been aware of many fundamental problems with the way support for HP SwitchStacks has been implemented in NAV. HP SwitchStack support was implemented in NAV 3.0 at NTNU, whose HP equipment consisted solely of HP SwitchStacks at that time. The result is code which is heavily biased towards SwitchStacks, to the point that NAV thinks HP devices are always SwitchStacks, no matter what. While we have been pondering alternative ways to model HP SwitchStacks (and consequently, Cisco switch clusters, which are basically the same thing), NTNU has entirely stopped using SwitchStacks. Today, they're experiencing bad side effects of the existing HP-related code in NAV. They're using some HP devices for routing, which NAV cannot handle at all (because of said "HP=SwitchStack only" view). No router ports are collected for these routers. Also, they seem to have many errors in topology information when HP devices are involved. Realizing that NTNU have stopped using SwitchStacks, we also do not know of anyone else who does, so now we are considering dropping support for SwitchStacks entirely from NAV. This way, the existing NAV code can treat HP devices like everything else. Preliminary tests of these changes at NTNU show promising results. So my question to the users of NAV is: Does anyone actually use virtually stacked HP switches? Will anyone miss support for this if removed from NAV? If there is no feedback on this issue, we will likely remove this support starting from NAV 3.5. -- mvh Morten Brekkevold UNINETT

Neat
by Vidar Faltinsen 09 Sep '08

https://launchpad.net/nav/+milestone/v3.5.0 ey, ey, ey very neat. I like. I am missing a couple of blueprints: * improvements in netmap o the best list is from the minutes of the July 1 meeting * remove vlanplot and tomcat (is this a blueprint?) - Morten: o we should remove the traffic map portion of seed db as well then? might complicate the possibility of running vlanplot as a contrib? o there are also some (3) vlanplot specific tables: http://metanav.uninett.no/devel:database#traffic_map - Vidar

Status on certain tasks
by Vidar Faltinsen 09 Sep '08

Dear summer developers, Could you please enlighten me, Kristian, * Is all of this done; http://metanav.uninett.no/devel:tasklist I will test, but your word is of value :) your blueprint status is "good progress"... * For the network map * Are we sure the rrd values you get are correct? On nav.uninett.no trd-osl has no load... there should be heaps of traffic here... * The absolute view... how is that coming a long? * Layer two cricket stats - can you display that? i.e. between two swithes Magnus/Thomas * For alert profile/user admin is the following solved; with reference to http://metanav.uninett.no/devel:tasklist - MB7: Admin can change his/her effective user ID - MB8: Support delayed SMSes Magnus; * When deleting a profile subscription you get an extra confirm page for the delete. The info presented there is not what one expect, it reflects the profile time period, not the actual subscription I was to delete... * Have you had a complete walk thru/demo of alert profiles with Morten? If not we should do this and look for potential bugs/missing stuff Thomas; * The new user admin panel returns an error message on navdev. Hard to test :) Are all the subtasks 1-5 of TA3 solved? - Vidar

Edit DB renamed to Seed DB, needs test and merge
by Stein Magnus Jodal 04 Sep '08

04 Sep '08

Hi, I've just spent an hour on renaming editdb to seeddb, as described in the https://blueprints.launchpad.net/nav/+spec/rename-editdb blueprint. The code is now running at navdev and is available at navdev:~jodal/nav/jodal/rename-editdb. 1) Morten and Vidar: could you please poke around at navdev a bit to test that everything seems okay? 2) Morten: could you please merge the branch or give me a green signal for merging before other branches diverges too much? I've changed code in large parts of NAV (including the infamous nav.django.urls) to accomplish the renaming, and would very much like to win the merge war by merging first ;-) Upgrade instructions are included at the blueprint status whiteboard. -- Stein Magnus Jodal UNINETT

Introduction to using Django with NAV
by stein.magnus.jodal＠uninett.no 28 Aug '08

28 Aug '08

Hi, I have just completed a first draft of the NAV+Django introduction, available at [1]. I know some of you would for sure had benefit of having this documentation available in June. I'm sorry about that, but now it's finally here. I would very much appreciate if those of you which have been using Django in NAV or elsewhere could take the time to read through the introduction and give some feedback. Both general feedback here at the mailing list and changes directly in the wiki are welcome, especially with regards to the future enhancements section. Hope the docs will be useful to some :-) [1] http://metanav.uninett.no/devel:django_introduction -- Stein Magnus Jodal UNINETT AS

Bugtracker moved from Sourceforge to Launchpad
by Kristian Klette 19 Aug '08

19 Aug '08

Hi all NAVers! Our new bugtracker is located at http://bugs.launchpad.net/nav All of the bugs that were reported on Sourceforge was imported, so all the data should be there. To simplefy bug-reporting for developers and other console-junkies, the nav-tip[0] now has a small tool called nav_bug.py in the contrib folder. Add this tool to your path and run nav_bug.py --help for more info about how to use the tool. I hope you all will enjoy using a more up-to-date bugtracker, and help us making NAV even better! - Kristian Klette [0]: http://metanav.uninett.no/hg/default -- Mvh Kristian Klette «Programs for sale: Fast, Reliable, Cheap: choose two.»
