We are using grafana dashboards by getting data from different sources. While displaying, we have a huge no of dashboard and panels.
When the data doesnt flow or source not configured properly, then we see No Data, instead of a graph.
Can you suggest any automated way to validate this ?
For now we are opening each dashboard and verifying each panel, we want to cut down this manual effort and human intervention as well.
To keep it simple
We want to know how many panels are not working across dashboards, which needs attention.
Thanks in advance.
