Configuring SNMP Trap

[ETSystems (Systems Support ET)]

Hi,

Can someone help me understand how to configure the SNMP trap for SAN switches in Checkmk?

SNMP traps are only supported by the Event Console:

The Event Console - Processing logs and SNMP traps

Why is described here:

Monitoring via SNMP - Monitoring of SNMP devices with Checkmk

@mschlenker Are you sure? I’m fairly certain we have used snmp traps with the CRE event console - AFAIK it works the same as documented.

I agree however with the notion of “if you have any other way of monitoring, always prefer that over snmp traps”

[mschlenker (Mattias Schlenker)]

You are probably right, I have to investigate differences of event console in commercial vs. OS editions and whether is SNMP traps is such a difference. Most of the event console article was written before my time at Checkmk.

hi @mschlenker

I read this document and did some tests but unfortunately, I cannot configure the snmp trap for a particular device. I am not having experience with snmp trap configuration.

hi,

is the issue, that the device might not be sending traps at all? Because that will be pretty device specific. Here, you’ll find people that know checkmk, however it’ll be less likely that we know a particular device. But try to give more details, maybe we can help

Or do you already receive traps but need help configuring the EC?

@gstolz
I have completed the SNMP trap configuration inside the device.
now I want to know the steps to configure the SNMP trap for the same inside checkmk.

Hi Benson,

to test it, you can create a catch-all rule with “text to match” set to .* in the event console of a test site and send your traps there.
You can then analyze what is being sent into the event console and create rulesets with the informations from the events that where created.
For Brocade SAN Switches i would recommend to use the SNMP checks.
As the others here i would always use snmp traps as the last resort and only if every other possibility to get info about the devices fails. SNMP Traps are “stateless” udp packets and you never know, if, when and what was send and if the traps really reached their target or if they where smashed by a firewall on the way.
