Missing Metrics for Datasource


I am using prometheus data source and i am missing some of the metrics that come with promethues

For example I’m missing a http_requests_total and won’t work or I can’t use process_resident_memory_bytes http_request_duration_microseconds_count

They just won’t show up in the dropdown is that something I have to add or what?

How can I add some of these metrics to the datasource?
