Using Prometheus and Grafana, I want to show how long a windows process has been running for, in a selected time range.
With:
<code>time() - min by(process) (windows_process_start_time{process="foo"})
</code>
<code>time() - min by(process) (windows_process_start_time{process="foo"})
</code>
time() - min by(process) (windows_process_start_time{process="foo"})
I can display this in a table for an instant type query so it only works if the process is currently running.
I’ve tried changing query type to range and with different (eg. max) aggregations on the whole query but can’t get it to work.
