Hi All,
I find myself back to working with Nagios after a long hiatus of using much
friendlier monitoring systems....
I'm trying to set up snmp trap monitoring, which I've dome in the past, but
I'm missing something that I just can't seem get. I can send a trap from a
system, the trap is received by the trap catcher, it's handed off to snmptt
for translation, which uses the EXEC line to put an external command in the
nagios.cmd file. That all works. But notifications aren't sent, and the
status of the service never changes.
So:
snmptrap -v 2c -c public util1 '' .1.3.6.1.6.3.1.1.5.5 ## runs on util2
Fri Oct 30 17:42:03 2015 .1.3.6.1.6.3.1.1.5.5 Normal "Status Events" util2
- An authenticationFailure trap signifies that the SNMP ## Shows up on
util1 in snmptt.log
[1446226923] PROCESS_SERVICE_CHECK_RESULT;util2;TRAP;1;An
authenticationFailure trap signifies that the SNMP ## Shows up in
nagios.cmd
So, it appears that everything is set up correctly, but Nagios isn't
processing the external service check command and setting the status to
warning and sending me an email.
Any ideas?
TIA,
Kenny
