Hi,
I am using 2.0.p22 as production monitor and am testing 2.1.p10 on my test machine.
First thing that I have noticed is that [Systemd Service Summary] is different for the same machine.
Monitoring the production machine from the OMD site sunning on it - I have:
Total: 129, Disabled: 3, Failed: 0
Monitoring the production machine from testing machine I have:
Total: 153, Disabled: 3, Failed: 1, 1 static service failed (fwupd-refresh)CRIT
The worrying detail is that fwupd-refresh is really in failed state, which production OMD fails to see (on itself).
