If you notice that certain users are not able to see any information in your Grafana dashboards on DKP, it is likely related to access control.
Ensure that they have the following set in the clusterrole that corresponds to that user:
- nonResourceURLs:
- /dkp/grafana
- /dkp/grafana/*
verbs:
- get
- head
- post
For more information about clusterroles, see the Kubernetes docs:
