title: PromQL Requests per minute
body: <p>I'm trying to create a graph of total <code>POST</code> requests per minute in a graph, but there's this "ramp up" pattern that leads me to believe that I'm not getting the actual total of requests per minute, but getting an accumulative value.</p>
  
  <p>Here is my query:</p>
  
  <pre><code>sum_over_time(django_http_responses_total_by_status_view_method_total{job="django-prod-app", method="POST", view="twitch_webhooks"}[1m])
  </code></pre>
  
  <p>Here are the "ramp up" patterns over 7days (drop offs indicating a reboot):

  <p>What leads me to believe my understanding of <code>sum_over_time()</code> is incorrect is because the existing webhooks should always exist. At the time of the most recent reboot, we have 72k webhook subscriptions, so it doesn't make sense for the value to climb over time, it would make more sense to see a large spike at the start for catching webhooks that were not captured during downtime.</p>
  
  <p>Is this query correct for what I'm trying to achieve? </p>
  
  <p>I am using django-prometheus for exporting.</p>
