We are using the 1-click-installed variant of the kubernetes monitoring stack. A few days ago Grafana stopped working, with the web panel reporting “an internal server error”:
{ “message”: “An error occurred within the plugin”, “messageId”: “plugin.downstreamError”, “statusCode”: 500, “traceID”: “” }
Has anyone encountered (and solved? :)) this issue? Kind regards

This error indicates that something has gone wrong internally with Grafana, typically due to a plugin issue or a configuration problem.
Use the following command to view the logs of the Grafana pod:
kubectl logs <grafana-pod-name> -n monitoring
Replace <grafana-pod-name> with the actual name of your Grafana pod. Check for any error messages or stack traces that could give more insight into what’s causing the issue.
- You can list installed plugins using the following command (inside the Grafana pod):
kubectl exec -it <grafana-pod-name> -n monitoring -- grafana-cli plugins ls
Look for any plugins that might be known to cause issues or have recent updates that could have introduced bugs.
If any plugins are outdated or known to cause problems, consider updating or removing them:
kubectl exec -it <grafana-pod-name> -n monitoring -- grafana-cli plugins update-all
Or remove a specific plugin:
kubectl exec -it <grafana-pod-name> -n monitoring -- grafana-cli plugins uninstall <plugin-name>
After updating or removing plugins, restart the Grafana pod to apply changes:
kubectl delete pod <grafana-pod-name> -n monitoring
Kubernetes will automatically recreate the pod with the updated configuration.
