Nagios Support Forum

Hi ,

I have enabled the snmptrap option in nagios , i am receiving the traps in /var/log/messges however same is not getting mapped to host that is configured and traps are not getting logged in "snmptt.log".

Please suggest what might be the problem.

Which "snmptrap option" are you referring to?

What document did you follow?

I have follwed "xavier.dusart.free.fr/nagios/en/snmptraps.html" and snmptrap option means i have enabled nagios to receive trap from devices. When i send a trap from device , i can see it is reaching nagios and can see the entries in /var/log/messages , but snmptt.log is not getting updated and also in nagios console i cant see the trap received for particular host.

Please remove the steps from the guide you followed, and instead use our documentation. It does say that it is for nagios XI, however it works great for Core as well, provided you are on a Centos or RHEL system. You can find it here:

The only part that does not apply, is that your mibs need to be manually placed in the correct directory and will need to be translated by the appropriate command.

i followed this but still not getting alert in console.

Please post here:

What is being shown in /var/log/messages

I have attached snmp log files. Eventhough traps are received in messages.log , i dont see any passive entry in nagios.log .

Let's have you tar up the existing snmptt.conf files for us.
Please post the resulting /etc/snmp/snmptt.tar.gz
