Symptoms
Advanced Monitoring doesn't show any data but one of the error messages below instead:
PLESK_ERROR: Dashboard not found
CONFIG_TEXT: *If you're seeing this Grafana has failed to load its application files*
1. This could be caused by your reverse proxy settings.
2. If you host grafana under subpath make sure your grafana.ini root_url
setting includes subpath
3. If you have a local dev build make sure you build frontend using:
yarn start, yarn start:hot, or yarn build
4. Sometimes restarting grafana-server can help
Cause
Incorrect permissions inside sw-cp-server proxy directory.
Corrupted installation of the extensions Grafana and Advanced Monitoring.
Resolution
-
Connect to the server via SSH.
-
Make sure that subdirectories of
/var/lib/sw-cp-server/proxyare owned bysw-cp-server:sw-cp-server:# ls -la /var/lib/sw-cp-server/proxy

In case permissions/ownership are different, remove the proxy directory:
# rm -rf /var/lib/sw-cp-server/proxy
In case the issue is not resolved,

Extensions > My Extensions > Grafana > More > Remove and,
-
Extensions > My Extensions > Advanced Monitoring > More > Remove.

Note: The following error message can be safely ignored:

-
-

still does't working after this procedure.
latest obsidian 18.0.32 / Ubuntu 20.04.1 LTS
I have found an explanation for my Plesk installation, leading to a workaround (not that great but it works).
If I open the browser console in the Network tab when I load the Advanced Monitoring page, it attempts to load the following URL: https://:8443/modules/grafana/service/login/generic_oauth, which fails due to the domain name being absent.
If I open a new tab with the URL after adding the correct domain name, it displays the Grafana page and all dashboards are available and working correctly.
So for me, and maybe for "dufresne", there is a problem with the Advanced Monitoring module where it is not able to get the domain name and inject it while building the redirection to the Grafana authentication URL.
Note: Reinstalling both Grafana and Advanced Monitoring extensions do not fix the problem.
After following these instructions the 'Advanced Monitoring' side bar disappears. If I then access Grafana from my extensions it sas "Looks Like there's nothing here".
Clicking the "Open Application" button does open Grafana in a separate tab.
Some clarity on this help article as to if this is the expected behavior would be appreciated. As the article is written, it makes it seem like after the 'uninstall/reinstall' it would appear back in a 'Advanced Monitoring' sidebar.
did not help.. same error
In my case Disk and Memory dashboards were not showing. To fix:
Go to Extensions > Grafana where an exclamation mark symbol will show - click Restart Integration and you should be good
When reinstalling as per procedure, on a vanilla cloud instance:
