SNMP Traps not working

[mzoumboulakis]

Hello,

I'm in the process of evaluating Nagios XI (2012R2.2 running on CentOS 6.4 i686) and I'm having trouble integrating the SNMP Traps functionality.
I've followed this document http://assets.nagios.com/downloads/nagi ... ith_XI.pdf and the Nagios XI server receives traps, SNMPTT does its bit (the traps are processed according to /var/log/snmptt/snmptt.log), the hostname matches exactly the hostname of the monitored hosts in NagiosXI, BUT, the service status in Nagios XI is always "Waiting for traps..."

I have some familiarity with processing (successfully) traps in Nagios Core - in Nagios XI, the documentation seems to be missing what program should be executed when a trap is received i.e. the EXEC part of snmptt.conf. In Nagios Core we used to execute /usr/local/nagios/libexec/eventhandlers/submit_check_result but this doesn't exist in Nagios XI.
Can you please tell me if I'm missing something obvious?

Thanks

If you installed the rpm from the document it should have put in a script /usr/local/bin/snmptraphandling.py

Code: Select all

EXEC /usr/local/bin/snmptraphandling.py ...

Thanks for that, it's all working now. The system had its own snmptt and I didn't read the doc carefully enough to note that Nagios supplied a different one.

IMHO, the document can be improved by adding a couple of lines to say that you need to translate your MIBs with a command such as:

Code: Select all

snmpttconvertmib --in=/usr/share/snmp/mibs/cpqhlth.mib --out=/etc/snmp/compaq.conf --exec='/usr/local/bin/snmptraphandling.py "$r" "SNMP Traps" "$s" "$@" "$-*"'

And then adding the contents of the .conf file to /etc/snmp/snmptt.conf.

And you need to configure your snmptrapd by adding the -On option in /etc/init.d/snmptrapd.

Thanks

I'm glad it's working now. Thanks for the tips on improving our docs!
