Hi All,
Please I need advice on fixing these errors.
I’m noticing these errors in grafana dashboard when importing these jason files (source # flux2/manifests/monitoring/monitoring-config/dashboards at main · fluxcd/flux2 · GitHub)

welcome to the :grafana: forum, @reppakayala

those json files imported without error for me. I was using Grafana 8.5.5

Thank you @mattabrams.
Actually, I am facing this issue and due to the reason, it’s not working.

Any idea/ hint to fix this issue, please?

Helm upgrade failed: failed to create resource: Internal error occurred: failed calling webhook “prometheusrulemutate.monitoring.coreos.com”: Post “https://prometheus-kube-prometheus-operator.metrics.svc:443/admission-prometheusrules/mutate?timeout=10s”: no endpoints available for service “prometheus-kube-prometheus-operator”

All these issues are fixed.

The grafana dashboards were working fine not sure suddenly stopped working.

How do troubleshoot it to find out the root cause?.

Rgds,
Ravindar

what @yosiasz said. also try increasing the verbosity of the Grafana server logs to debug and note any errors. For printing to console, set the console logs to debug as well.

@reppakayala were you able to find the cause of the issue?

This can happen if there is a parsing error or invalid characters in data links or template variables, especially in older versions of Grafana.

Other things to check if you run into this:

  • Are you on a current version of grafana?
  • Is the dashboard compatible with your version? Sometimes community-contributed dashboards can be out of sync with the version of grafana you have.
  • Use Chrome Developer Tools or similar and check the console when the error occurs - often there are hints about what resource is causing the issue.
  • What do you see in the query inspector response?
