Trouble with SNMP Monitoring

Unanswered Question

I am currently trying to set up nagios to monitor SNMP traps and to pull CPU information off of my 2610XM and am having NO Luck.


I have tried to enable every snmp-trap known to man, however when I do an snmpwalk from my server, I am not seeing the following OIDs that I need to see. Can anybody help me?


I am positive of the following

-SNMP community strings match

-SNMP configured to go to the nagios host


What command needs to be entered to send the below OIDS? And If I enter that command and they aren't showing up, what could a possible reason of why they aren't showing up be?


$oid_sysDescr = ".1.3.6.1.2.1.1.1.0";

$oid_cpu5min = "1.3.6.1.4.1.9.2.1.58.0";

$oid_tempState = "1.3.6.1.4.1.9.9.13.1.3.1.6.1";

The OID for sysDescr is correct. You should be able to poll that assuming the community string is correct.


The oid for avgBusy5 is also correct, but this object is deprecated. While it should work, you might try .1.3.6.1.4.1.9.9.109.1.1.1.1.8.1 instead.


Provided the 2610XM has the necessary hardware (I know a 2620 does), the OID for ciscoEnvMonTemperatureState is also correct.


Now, be aware that none of these are traps. Nagios would need to POLL these objects via standard SNMP polling. There is a trap which will contain ciscoEnvMonTemperatureState, but only if there is a change in the temperature state (e.g. if the temperature goes from normal to critical). To enable that trap, you would need:


snmp-server enable traps envmon
