title: how to add an alert exclude window for Azure alert
body: <p>We were setting up Azure alerts for Our Azure VMS.</p>
  <p>But facing some difficulties in below scenarios and would need guidance from the experts</p>
  <ol>
  <li><p>For the basic alerting like Status of the server, CPU USage , Memory consumption, and avalaible disk space, etc.. What is the vest possible type of alert, metric or log query ?</p>
  </li>
  <li><p>Tried to configure Metric alert, CPU and Memory metrics were there.  but for Disk size usagethere were no direct metrics ( requirement is to trigger alert when the datadisk and oz disk size of linux vm is less than 3o0% avaialble)</p>
  </li>
  <li><p>The import point to get clarify is that, there are no options to exclude the alert for a particular period of time say, during offf work hours , at that time our machines will be in stoped status. ?</p>
  </li>
  </ol>
  <p>Any suggestions are highly appreciated.</p>
