[Release] Checkmk stable release 2.2.0p18

Please note that 2.2.0p18 has an issue with the Event Console. If you are using the Event Console, we recommend to wait for 2.2.0p19. Events might not be processed after an update. Please execute and apply two (dummy) config changes to reenable events processing.

Subsequently, to apply a config change, you have to reload the EC another time after an activate changes to apply the latest config. If you are using MKP’ed rule packs, these rule packs might not be considered in the Event Console.
We are working on a fix and will release a fixed version shortly.

We greatly thank you for using Checkmk and wish you a successful monitoring,

Your Checkmk Team

Note: anyone who uses the EC should be carefully testing after switching to p18 (or stay on p17 or lower and use mitigation for the security fixes.)

Checkmk - version 2.2.0p18 - syslog-like message logging seems not to work and 2 open Support tickets seem to indicate the EC is not working as it should and discarding some to all incoming events. (maybe only in some cases, investigation ongoing.)

Any updates?
Can you be already more specific?

Hello @gstolz,
just want to be safe. This is not a problem for the RAW version?


If I’m not mistaken, the Event Console / mkeventd is identical between Enterprise, Cloud and Raw, so CRE would be affected as well.

I’ve not gotten any updates yet.
What I saw: Debug of rule execution is missing, so any analysis is missing. This however is not mission critical.
The other ticket is handled by @jodok.glabasna and seems to affect actual processing of incoming invents.

We just updated to p18 and also faced an issue with that. In our case, it even doesn’t listen on its port.
@checkmk team, I understand that issue is not critical enough to pull the release, but it would be really helpful if such issues could be posted as an annoucement so that we get this information proactively.

not sure if it not got pulled unofficial

seems p19 is set

Thx! Unfortunately this 14859 FIX Event Console: Fix events not created after initial activat… · Checkmk/checkmk@9d9a89d · GitHub fixes the start of the console again but tcp port still isn’t open

We added a download warning yesterday to the website after we were made aware on this. This download warning will be extended a bit further soon (waiting for a sync).
I added a note here in the announcement as the warning will not be read by users who already have downloaded p18.
We will in the future also add warnings into these threads.


p19 is released which fixed again the Event Console.
