title: Prometheus count metric - reset counter at the start time
body: <p>How can I get the real count metric in Prometheus?</p>
  
  <p>Currently, count metric gives running information - like till now how many requests have hit a certain endpoint. </p>
  
  <p>But I want numbers like from 9:00 AM to 5:00 PM on a certain day, how many times my endpoint got hit? Can it consider counter value as 0 at 9:00 AM and do the calculations?</p>
