Neil,

Hi all,

I’m trying to get SNMP Traps from VMWare showing up in Xymon.

I think the issue is with the trap format from VMWare and I suspect I may need to tweak my snmptt.conf file for this.

I have attached my snmptt.conf file and here is a an example of what I am seeing in my /var/log/messages file. (Text in italics has replaced what actually shows in the log for security reasons)

It's not clear that snmptt is actually being invoked.

In my logs I see each trap twice - once the raw snmptrapd log and once processed by snmptt - note that snmptt can format a message however it likes, discarding trap params according to the FORMAT statement (which is static text in the example below - depends what snmpttconvertmib finds by default)

Jul 10 07:45:45 loghost snmptrapd[5438]: 2011-07-10 07:45:45 tempmon [10.x.x.x] (via UDP: [10.x.x.x]:51794) TRAP, SNMP v1, community xxx#012#011PowerNet-MIB::apc Enterprise Specific Trap (PowerNet-MIB::apcEnvLTIncTempRateViolationCleared) Uptime: 24 days, 18:57:56.83#012#011PowerNet-MIB::mtrapargsString02.0 = STRING: "XXXXXXXX"#011PowerNet-MIB::mtrapargsString03.0 = STRING: "Main Module"#011PowerNet-MIB::mtrapargsInteger04.0 = INTEGER: 0#011PowerNet-MIB::mtrapargsInteger.0 = INTEGER: 1#011PowerNet-MIB::mtrapargsString04.0 = STRING: "Temp Sensor MM:1"#011PowerNet-MIB::mtrapargsString.0 = STRING: "MM: Short-term increasing temperature rate of change violation cleared for 'Temp Sensor MM:1' at 'Unknown'."

The trap above is a vpxdTrap which according to the definition has 6 parameters - they seem to match your trap above.

EVENT vpxdTrap .1.3.6.1.4.1.6876.50.0.201 "Status Events" Normal FORMAT $* SDESC

This trap is sent when entity status changed. Variables: 1: vpxdTrapType 2: vpxdHostName 3: vpxdVMName 4: vpxdNewStatus 5: vpxdOldStatus 6: vpxdObjValue EDESC

From what I can see it appears that VMWare sends multiple OID’s in the same trap.

Has anybody got this working or can suggest a solution?

For a start, verify that snmptt is actually working.

David.
