SNMPTT not deleting traps, mysql errors in log

Posted: Fri Jan 13, 2012 3:09 pm

Quick description of the service:
- Remote host runs rsyslog with the omsnmp module
- omsnmp sends specific rsyslog messages to the Nagios host
- Nagios runs snmptrapd to catch the traps, deals with them using snmptthandler
- Next is snmptt, which decodes the trap and submits to Nagios
- Nagios is running 'dummy' services under which the alerts are sent out

So far, everything appears functional except that the traps are not being deleted from /var/spool/snmptt.

Any ideas? I figure there is something bigger going on because of the below errors. I have tried rebooting the Nagios host just to be sure.

The error in /var/log/messages follows:

the next_notification is being set to a time too fare into the future. 3218644415 = Tue, 29 Dec 2071 19:53:35 GMT and the mysql function FROM_UNIXTIME won't accept it and returns NULL

Ah, that's interesting. For some reason we had the alert setting interval set at a really high number, so maybe that was changing the SNMP trap date...

I've set it back to default and pointed the servers at the new Nagios host, so I will report back. Thanks.

Ok, figured it out! (the above wasn't it, btw)

Here's what we're getting in /var/log/messages

Code: Select all

Jan 16 09:07:51 tor-nagios-02 snmptt-sys[504]: Can not open log file /var/log/snmptt.log
Jan 16 09:07:51 tor-nagios-02 snmptt-sys[504]: Unable to delete trap file #snmptt-trap-1326722864817018 from spool dir
Jan 16 09:07:56 tor-nagios-02 snmptt-sys[504]: Can not open log file /var/log/snmptt.log
Jan 16 09:07:56 tor-nagios-02 snmptt-sys[504]: Unable to delete trap file #snmptt-trap-1326722864817018 from spool dir
So I said, why would snmptt-sys not be able to open that log file, or delete the trap from the spool?

Permissions, of course! The /var/spool/snmptt directory was still owned by root (should be owned by snmptt:nagios), and needed different access rights.

Anyways, that's the theory. Will update when another trap comes through.

Yep, that did it! Just permissions.

Last issue to deal with is clearing the alerts back to green. Will be going off of this to start: http://snmptt.sourceforge.net/docs/snmptt.shtml
