Set up SNMPv3 Traps

Hello

I have just set up my CheckMK according to this post:
https://forum.checkmk.com/t/kein-empfang-von-snmp-traps-in-event-console/18872/5?u=dom_666
I have also made a Event Console Rule to catch all events matching the syslog facility “snmptrap”.
From the host I want to monitor, I can send test traps to the receiver.
But I don’t get any event.
(The host sending the traps is on a remotesite, I haave also tried sending the traps directly to the Master CheckMK Site, with the same result.)
I have Checked the firewall and the required Ports are all open.
I can also see traffic from the host to the CheckMK Server (UDP Port:162).

So I guess there is still something missing in my CheckMK config.

I want to use SNMPv3 Traps.

Thank you

Hi @dom_666

Did you configured settings of event console ? Specially Credentials for processing SNMPTraps in EC Settings ?

That’s might be what you’re missing.

Hi @ricardoftribeiro
Thanks for your reply.
Yes I did enter the credentials as mentioned.
I followed step by step the manual in the link from my question.

Is there a way to log failed snmp traps in checkmk?
The firewall on the checkmk server is inactive.

On the rule try this :

That would do the trick … :slight_smile:

This is not going to halp, as I already have a event console rule to catch any event.
I meant, if there is an error log from checkmk that shows what was sent to the server and maby blocked or handled in the wrong way.

I would also appreciate a step by step how to manual to setup SNMP trap handling in checkmk.
