Hi,
Can't start the plesk-ext-monitoring-hcd.service demon, with the following error:

Is there a way to properly diagnose/resolve?

Have you tried reinstalling both Grafana and the Monitoring extensions?

 

[AYamshanov]

What versions of the extensions are used? Do they have any updates available?

Hi,
It's now working, probably an update/reboot in the meantime and everything now works....
