[Danny325]

I did an upgrade on a newer vps with ubtuntu 18.04 (old one 14.04 i backed up everything), now on the new vps Grafana/advanced monitoring does not work anymore (onliest thing).
I tryed to remove on plesk installer and isntall it again witouth success.

Getting the message when launching advanced monitor:
Dashboard not found

I found the solution:
running
dpkg -r --force-all grafana

removing grafana from extension

reinstall grafana from extension
