CMK version:
2.4.0.cce

OS version:
Debian 12

Hello,

since the 2.40 upgrade the service Check_MK Discovery has state UNKN on every docker server.

The problem exists on agents with version 2.3 and version 2.4

Thanks for your help!
Best regards Chris

Hey,

I have got the same issue. I have installed every beta update in 2.4 branch and it worked until the end. So it has to be a werk in the final release.

Additionally this issue only exists at snmp hosts with special settings for periodic service discovery (default is working). After deleting my special rule error is gone.

We’re looking into this ASAP

Moved over for tracking into the beta category (even though beta is over)

I have written a patch. It should become available with the next patch release.
