NAV workshop
by Vidar.Faltinsen＠uninett.no 01 Jun '05

01 Jun '05

Hi, We are planning a NAV workshop here in Trondheim on monday June 13. As we suspect this will only attract a Norwegian audience, the following is in Norwegian. (If I am wrong, please give me a hint): Vi har laget wiki-sider som beskriver programmet. Programmet er p? mandag 13. juni fra kl 15->. [1] S? alle NAVere - meld dere p? (en del av dere er forh?ndp?meldt)! Gj?r oppmerksom p? at vi m? sette en grense oppad. I utagnspunktet 50 stk. Vi vil kanskje ogs? m?tte gj?re en begrensning med antall fra hver enkelt institusjon om n?dvendig. Les mer p?: * http://metanav.ntnu.no/moin.cgi/NAVFagseminar Jeg kan ogs? r?pe at vi i neste uke kommer med en NAV 3.0 release candidate. F?lg med. [1] Det er lagt til dette tidspunktet bl.a. fordi det korresponderer med et gigacampus arbeidsgruppem?te som er dagen etter (dette m?tet diskuterer overv?kning mer generelt og deltagere er de som inng?r i arbeidsgruppen, disse er forh?ndsp?meldt NAV fagseminaret). -- mvh - Vidar >From magnus at ntnu.no Wed Jun 1 17:01:33 2005 From: magnus at ntnu.no (Magnus Nordseth) Date: Wed Jun 1 16:01:35 2005 Subject: [Nav-users] Another questions about vlanPlot In-Reply-To: <s29dd972.064(a)HVO-3.hivolda.no> References: <s29dd972.064(a)HVO-3.hivolda.no> Message-ID: <20050601140133.GH17281(a)stud.ntnu.no> Peder Magne Sefland: > I'm running nav3 on debian-sarge and found the file under > > locate vlanPlot.py > /usr/lib/python2.3/site-packages/nav/web/pyproxy/vlanPlot.py > /usr/lib/python2.3/site-packages/nav/web/pyproxy/vlanPlot.pyc > /usr/lib/python2.3/site-packages/nav/web/pyproxy/vlanPlot.pyo > > I made a copy of the original file and tried to do some changes here, > but no success. > How do I manually set the hostname or ip-address? It assumes you are running tomcat, the cricket front end and the NAV frontend on the same server. This could be a bit inflexible for some installations. The hostname is defined on the line server = req.server.server_hostname which extracts the hostname from the current http request. You can modify this line so it suits your needs. However, this hostname is used for vPServerURL, lastURL, cricketURL and netflowURL. If you want different hostnames for only some of them, you have to modify how the params are defined. I probably should move all this out to a config file some day. Also note that you have to restart apache after you have made your changes to ensure mod_python reloads the new file.

You are quite right; it seems it was removed by another developer.

I have tried your solution Kristian, and it got better. I don't get BoxDown 0 d, 00 h, 00 min anymore, but I still get too many alerts with very short time between down and up. This is an automatically generated message from NAV: Box volda-myrane1-MB-sw200.hivolda.no (158.38.86.6) is down since 2005-05-28 17:57:27. This is an automatically generated message from NAV: Box volda-myrane1-MB-sw200.hivolda.no (158.38.86.6) is up since 2005-05-28 17:58:08.

I might get an alert that https is down on a server, but if I try that server right away it resond just fine.

We should also supply a Device Compatibility Matrix equivalent to the netdisco version (http://snmp-info.sourceforge.net/DeviceMatrix.html) An idea is to adopt a similar/elaborated classification, introduce a wiki page at metanav and have the nav community participate in testing and doumentation. This will be of great value to the community, it will be easy for new users to see what we support, easy for us to see where the current problems are, etc. > Creating a perl binding which focused on easy of development would solve this > problem, but it is of now uncertain if resources are available to implement > something like this. We will discuss it internally and announce any decision > this list. We should give this serious thought. We definitely need a mechansim which invites contributions from the community. I will internally (ntnu/uninett) suggest an intense equipment test program where we test variuos new equipment in a structured manner. In the process we should look at improving logging and in the end provide a cookbook / check list for how to test a new switch/router in NAV. A device can be supported in NAV on different levels: 1: basis: only status monitoring of the device. no information on ports (l2 or l3 ports) 2: information on ports but no vlan information. This also includes cricket/rrd statistics 3: physical topology detected. machine tracker capable 4: full topology: vlan information (trunk and none trunk ports) Variuos log files / web pages should be checked in the process from initial seeding in edit database untill you reach level 4. Worst- and bestcase timeframe should also be dedumentet - Vidar

Suse Linux Enterprise Server (SLES) 9 install documentation?
by TristanRhodes＠weber.edu 19 Mar '05

Morten, Thanks for putting together the NAV installation instructions for SLES. I have a few thoughts.... 1. Are there commands that can be used to install the long-list of Yast packages, or is the GUI required? (I am used to "apt-get install apache") 2. Regarding the manual package installations: Can any of these be installed with Yast? I noticed that IPy is installed manually, and it is in Yast. Is this due to a required version of IPy? (There may be other similar packages like IPy). 3. I have only recently discovered NAV, and I am very thankful for all the work that has been put into it. I am also very pleased that it has been released under the GPL license so that we can use it! Can I ask when NAV 3.0 is expected to be finished? (Q2, Q3, or Q4 2005?) Thanks!

Yes, thank you for reminding me (I had forgotten all about this). I will try to put something up by Friday. All testing and suggestions are welcome :-) - -- Morten Vold NTNU ITEA Integrasjonsgruppen

Is this possible in nav3? In nav3 you have multiple options here: 1) You can adjust your alert profile to suppress alarms from the netbox in question. This solves the problem for you, not for everybody. You may alse do this suppression based on severity. We have a default severity scheme in place, depending on the box in question this may help you. 2) You can put set the device on maintenance. Use the messages tool, select the maintenance tab. Select the netbox and attach a message to this. This options stops all monitoring of the device for the time period you specify. 3) You may adjust timers in pping and/or event engine, see pping.conf, eventEngine.conf (maybe Kristian can elaborate here). Please note that these adjustments are on a "global" basis. - Vidar

snmp timeout when adding a 6509 GSW

Is it because of a >misconfiguration on the GSW? No. This is normal as the device does not reply to SNMP requests on a VLAN it does not recognize (1002 in this case). Since NAV does not know which VLANs are valid for a given device it will try several, some of which might not be valid, and this can result in the above message. It should be safe to ignore in this case, however. -- Kristian

Use SNMP::Info to manage device types?

I agree Vegard, Netdisco is a neat application. I would love to see the best of both applications combined.

I don't know enough details about the NAV database, but I would assume that alternative methods for harvesting SNMP data for insertion into the NAV database would be possible. Wouldn't it? List of devices supported by SNMP::Info: http://snmp-info.sourceforge.net/DeviceMatrix.html BTW, people taking interest in the SNMP::Info package should also be aware of the netdisco application (http://netdisco.org) for which SNMP::Info was created. netdisco is an application similar to NAV in many respects. It is implemented solely in perl, has auto-discovery capabilities, has a full-fledged API for extensions, the main interface is web-based but a command line interface is provided as well. A nifty functionality is layer 2 traceroute which displays switch port details along one possible route between two IP adresses. netdisco also provides a 'Duplex Mismatch Finder'. The web interface in netdisco is more basic, nowhere near as slick as NAV, but I guess some ideas from netdisco could be incorporated into NAV. - Vegard - _______________________________________________ Nav-users mailing list Nav-users(a)itea.ntnu.no http://mailman.itea.ntnu.no/mailman/listinfo/nav-users >From kreide at online.no Mon Mar 14 16:16:50 2005 From: kreide at online.no (Kristian Eide) Date: Mon Mar 14 16:16:53 2005 Subject: [Nav-users] Use SNMP::Info to manage device types?

I believe there is a way to manually add device types to NAV, and there is a Wiki page listing many device OIDs. This works, but it may be a duplication of effort. There is a perl module named SNMP::Info that provides an object-oriented interface to Network Devices and data stored in SNMP MIBs. http://snmp-info.sourceforge.net/ If this module could be integrated into NAV, many different network management projects can add devices to this module, and all will benefit from it.

You can add support for device foo in NAV by writing a device handler in getDeviceData subsystem, which shouldn't be too difficult, I suggest using one of the existing handlers as a starting point.

I don't know enough details about the NAV database, but I would assume that alternative methods for harvesting SNMP data for insertion into the NAV database would be possible. Wouldn't it? List of devices supported by SNMP::Info: http://snmp-info.sourceforge.net/DeviceMatrix.html BTW, people taking interest in the SNMP::Info package should also be aware of the netdisco application (http://netdisco.org) for which SNMP::Info was created. netdisco is an application similar to NAV in many respects. It is implemented solely in perl, has auto-discovery capabilities, has a full-fledged API for extensions, the main interface is web-based but a command line interface is provided as well. A nifty functionality is layer 2 traceroute which displays switch port details along one possible route between two IP adresses. netdisco also provides a 'Duplex Mismatch Finder'. The web interface in netdisco is more basic, nowhere near as slick as NAV, but I guess some ideas from netdisco could be incorporated into NAV. - Vegard - >From fredrik.holmberg at luh.hihm.no Mon Mar 14 15:40:38 2005 From: fredrik.holmberg at luh.hihm.no (Fredrik Holmberg) Date: Mon Mar 14 15:43:54 2005 Subject: [Nav-users] " ... violates foreign key constraint "$1" Message-ID: <4235A266.7030309(a)luh.hihm.no> Keep getting these messages in getDeviceData.log: Mar 14 15:21:37 2005 xxx-gw.uninett.no_01 GwportHandler-6-NEW GWPORTPREFIX Gwportprefix: gwip=128.39.xxx.xxx hsrp=false prefix=128.39.xxx.xxx/32 (0) (e1ca74) Mar 14 15:21:37 2005 xxx-gw.uninett.no_01 GwportHandler-3-HANDLE SQLException: ERROR: insert or update on table "gwportprefix" violates foreign key constraint "$1" Does anyone know of a way to fix this, or doesn't it have any particular effect on NAV3 (beta 10)? - Fredrik Holmberg >From kreide at online.no Mon Mar 14 16:02:01 2005 From: kreide at online.no (Kristian Eide) Date: Mon Mar 14 16:02:09 2005 Subject: [Nav-users] Use SNMP::Info to manage device types?

New OIDs can be added via the web interface, and NAV will automatically detect which devices support the new OIDs. Data collection is done by the 'getDeviceData' daemon, which uses a plugin-based architecture. The API for this is resonably well documented in Javadoc, however, it is a fact that familiarity with Java programming is required in order to create new collection plugins. Unfortunately it also seems many system administrators are much more familiar with script languages and the barrier to entry is thus high. Creating a perl binding which focused on easy of development would solve this problem, but it is of now uncertain if resources are available to implement something like this. We will discuss it internally and announce any decision this list. -- Kristian
