Systemd services CRIT after update to 2.3.0p26

After the upgrade to version 2.3.0p27 some of the monitored Linux servers shows the following information:
Systemd Service Summary Total: 169, Disabled: 9, Failed: 2CRIT

What i found out is the following:
All affected server have a “Exclude units matching provided regex patterns” rule to ignore failed services. Now it seems that the rule is not working anymore. It recognizes the excluded service (that’s why the name of the failed service isn’t shown), but it states the service as critical and trigger an alert instead of ignoring it.

This is a known problem - discussed in the p27 release post.
There is also a solution for the problem with a small mkp available here.

[Release] Checkmk stable release 2.3.0p27

Hey Andreas, Would you mind testing this MKP out? systemd_units-0.0.2.mkp (7.9 KB) This one should ideally address all of the issues you mentioned in your comment. Thanks!
