Want to know about Grafana With Prometheus


I am Using Prometheus in grafana. I am executing this query “haproxy_backend_connection_errors_total” and it is generating graphs properly. I want to know whether I am able to get the details of the result of above mentioned query.

For example here I have configured backend for localhost:9000 and I have not started this server and executing the frontend. It will generate the backend error as the server is not started. So I want to know the details or reasons behind the failure when I am running this query in grafana.

If yes, then please guide me the way.
