No I’m afraid that wasn’t the solution. That was just the solution to the discovery crashes of a host. The overall nagios service kept stopping and continues to. We started over from scratch and rebuilt the monitoring on 2.4.0 while having the volume data in a separate local docker instance to refe…

Moved over for tracking into beta category and asked @chauhan_sudhir internally to replicate

Thanks for reporting the problem. I have some questions: This service was upgraded from 2.3.0 latest to 2.4.0 latest and has been failing since. Which version of 2.3 in particular you had before ? [image] UnderTheSea1: No custom module or code. Can you also check if any custom files unde…

Humm the process is stopping again this am and is repeatably stopping again after no changes overnight.

[image] chauhan_sudhir: Looks like some local files are still there. Did you used Yum MKp at some point and then removed it because the update complained about it ? That’s correct, it broke I think 2.2 → 2.3 at one point so we removed it. [image] chauhan_sudhir: Was the CCE downgraded to…

Can you share the $OMD_ROOT/var/log/update.log and the output of “cmk -U -vvv” as site user please ?

Your update.log doesn’t say anything about the downgrade from CCE to CRE. Anyways: Does the problem still happen ? When you start the core, does it stil get stopped ? Can you also share the $OMD_ROOT/var/log/web.log ?

The downgrade would have been a long time ago. Just wanted to mention that. Yes, its still happening Yes the nagios service keeps stopping. Note yesterday it was stopping every few mins in the am then it worked for hours with no issues only to resume stopping again overnight. Sure , this is the mo…

Nagios service stopping post upgrade to 2.4
