How to add sensorgateway probes to nav ?
by FOUR Ludovic (EXT) 17 Dec '21

17 Dec '21

Hello, I'm using NAV 5.2 and I would like to add a couple of Serverscheck temperature probes that monitor our network racks Product reference is detailed here : https://serverscheck.com/sensors/baseunit.asp I'm trying to add the probes by following the adding AKCP probe tutorial. I made this : 1/ Translate the sensorgateway.mib into SERVERSCHECK-MIB.py with smidump command 2/ Copy the python file to folder /opt/venvs/nav/lib/python3.7/site-packages/nav/smidumps There's a ServersCheck module used in MIB file, that i'm using to interrogate directly the probe I can get the temperature value with snmpwalk -c community -v1|2c <IP of the probe> ServersCheck:sensor1Name.0 If I translate into OID with snmptranslate command, I get this OID .1.3.6.1.4.1.17095.3.2.0 3/ Create the file serverscheck_mib.py with those lines to /opt/venvs/nav/lib/python3.7/site-packages/nav/mibs from twisted.internet import defer from nav.mibs import reduce_index from nav.mibs.mibretriever import MibRetriever from nav.smidumps import get_mib class ServerCheckMib(MibRetriever): mib = get_mib('SERVERSCHECK-MIB') @defer.inlineCallbacks def get_all_sensors(self): result = [ { 'oid': '.1.3.6.1.4.1.17095.3.2.0', 'unit_of_measurement': 'celsius', 'precision': 1, 'scale': None, 'description': "Ambient temperature", 'name': "Ambient temperature", 'internal_name': "Ambient temperature", 'mib': 'SERVERSCHECK-MIB', } ] defer.returnValue(result) - Add the following lines to /etc/nav/ipdevpoll.conf (note sure of iana code of serverscheck manufacturer. should be 25432) 25432 = ServersCheckMib SERVERSCHECK = SERVERSCHECK-MIB At this point i'm stuck (ipdevpoll log empty) and I still can't get sensors readings into NAV and it doesn't recognize the probe type into collected info of the seedDB probe page Any ideas of what I'm doing wrong ?

advice on upgrading nav 4.9.5 on debian 8.11 to nav 5.3 ideally debian 11
by Mischa Diehm 10 Dec '21

Hei all, we have a larger NAV setup with a bit more than 1000 Cisco Switches and use quite a lot of the features supported in NAV. Since our setup is a bit dusty we plan to upgrade (nav 4.9.5 on debian 8.11 to nav 5.3 ideally debian 11). I wanted to ask for your advice on the upgrade paths possible. We use a external db server that hosts the postgres db. Requirements/Whishes: - it would be great to keep the devices history and graphs so a simple dump.py and reinstall would be a bit lossy - it would be nice to start with a fresh installed debian 11. Is there a good/preferred path that we could follow? Thanks for any ideas and suggestions, Mischa p.s.: Any ideas / timeframe when nav will release debian 11 packages? -- narrowin.ch /\ network & security
