All of the ‘systemd’ fails I’m currently fighting are timeouts (agent runs greater than 60 seconds), and no matter what I try, they will still exist.
I did get an e-mail stating that the systemd check does have a filter.
Go to ‘WATO - Configuration’; ‘Host & Service Parameters’; Search for ‘systemd’; Select ‘Systemd Services’; and add a filter for ‘check_mk@*’
