Plesk dashboard widget monitoring stuck: grafana has no rules loaded

[senthil]

Symptoms

• Plesk Obsidian running on a Debian-based operating system
• Configuring grafana in debug mode in /etc/grafana/grafana.ini shows no rules added:
  
  Code Select Expand
  logger=alerting.scheduler t=2025-02-12T12:33:31.008195604+01:00 level=debug msg="Scheduling update"

logger=secrets t=2025-02-12T12:33:50.255870488+01:00 level=debug msg="Removing expired data keys
from cache..." logger=secrets t=2025-02-12T12:33:50.256088386+01:00 level=debug msg="Removing
expired data keysfrom cache finished successfully"


Cause
Grafana's installation is corrupted and this prevents the Grafana and Monitoring extensions in Plesk from working
as expected because they both depend on Grafana being operational.

Resolution

• Connect to the server via SSH
• Remove the Grafana extension:
  
  Code Select Expand
  #plesk bin extension --uninstall grafana
• Remove the Monitoring extension by executing the following command:
  
  Code Select Expand
  #plesk bin extension --uninstall monitoring
• Remove Grafana left-over files by executing the following command:
  
  Code Select Expand
  #apt-get remove grafana && rm -rf /usr/share/grafana /etc/grafana /var/lib/grafana
• Reinstall both extensions in this order:
  
  Code Select Expand
  #plesk bin extension --install grafana
#plesk bin extension --install monitoring
