Background: I have a linux server where I configured my jenkins and installed the prometheus plugin to scrape the jenkins instance metrics. I am using grafana dashboard to visualize and monitor the jenkins server. In grafana I have used the grafana's pre-configured jenkins dashboard for jenkins monitoring and prometheus datasource to import the metrics to Grafana.

> Jenkins url - https://<ipaddr>:8080/test
> Prometheus scrape jenkins metrics url: https://<ipaddr>:8080/test/prometheus

Problem statement: Whenever I stop the jenkins process on my jenkins server then the grafana dashboard show as "no data available" or whenever there is some issue with prometheus plugin then also it shows "no data available". I know this is happening because prometheus is unable to scrape the metrics since the jenkins server itself is down which results in blank data passed to grafana from prometheus datasource. I just wanted to know is there any way where I could display the specific metrics in grafana which says jenkins down when jenkins process is stopped. Grafana should say the exact error at jenkins instead of just saying "no data available". Is there any custom grafana way to display the error message atleast when there is a problem with jenkins server itself.
