Check_Discovery Crash

Troubleshooting
1

Hi!

The Check_MK Agent version is 1.5.0b7, the OMD version is 1.5.0 Raw Edition and the host is a RHEL 5.9.

The check_discovery service from my xyz_host is crashing.

The output of the command cmk --debug -vvI xyz_host is:

Discovering services on: xyz_host
xyz_host:

I’m kinda lost here. Did someone go through this? How can I solve it?

Can you provide how the <<<mem>>> section of your agent output looks like?

3

My agent output is missing this <<<mem>>> section.

4

That’s interesting - Why do you have then an “mem” check in your discovery?
Somewhere must be an <<<mem>>> section.

5

Well, that is something that I don’t know how to answer.

The Memory service has the status Unknown. Some times the Memory service return Ok and then the agent output has the <<<mem>>> section, otherwise not.

6

Then i would inspect how your agent output is generated.

As this is not a normal agent call, i think there is somewhere a problem with the generation of your data.
