Allow one fail in Systemd Service Summary (systemctl --all)?

Following a reinstall of Proxmox (which was a test to see what that would look like if we ever need it) we have an error detected by check:

Looking at it it seems like a heavy lift to fix the issue on the Proxmox box (like wipe the whole thing and start over or wait for a bug fix of some kind another person reported a similar thing that we see [solved] zfs-import-scan failed | Proxmox Support Forum).

Is it possible for me to tell checkmk to allow 1 fail on this monitor somehow? I would sort of like to know if anything else in systemctl --all fails so I hate disabling the check, but I don’t think we’re fixing this one.

Also, why did I have two Systemd Socket Summarys?

CMK version: 2.2.0p24
OS version: Ubuntu 22.04

Error message:

Output of “cmk --debug -vvn hostname”: (If it is a problem with checks or plugins)

Systemd service summary : This monitors the state of linux services provided by “systemctl --all”

Systemd sockets summary : This monitors the state of linux sockets provided by “systemctl --all”

With the following rule, you can exclude the systemd service and make the check :green_circle:

Perfect. Thanks a lot.

Can you please mark the answer as the solution if it solved your problem?
