title: Prometheus monitoring drilled down metric
body: <p>Since prometheus is a pulled based metric tracker.</p>
  
  <p>Now lets say I have a simple service and I Need to expose metrics for Prometheus to scrape, Now I do that with one of the clients of the language, configured Prometheus to poll at a frequency of 15secs this API of metrics, Now I have a count metric, Prometheus server at time instance at time t saw count x, At time t+15 sees count y</p>
  
  <p>Now becuase of the scrap interval(pull model) I don't have any idea wether the increase of count x to y had a steady slope or a Spike of requests came in at t+10</p>
