title: ThreadCount Metric in AzureAppService
body: <p>I have an <code>S2</code> AppService plan that has a webjob with an instance count of <code>1</code> (default).
  The webjob basically reads from a service bus topic using <code>5</code> (configurable) concurrent threads.</p>
  <p>Recently, we had a huge load coming in and the webjob was unable to quickly read through all the messages in the SB Topic, so we increased the instance count from <code>1 to 10</code> and the threads from <code>5 to 10</code>.</p>
  <p>I am trying to understand if the webjob's thread count has any relation with the appservice's threadcount metric?
  If yes, I still see the max thread count as <code>35</code>.
  If no, is there a way to correctly measure the number of active threads of my webjob at any instance of time?</p>
