title: How to restart Azure App Service Instance
body: <p>I have an Azure App Service that contains 1 Web App with 1 slot.  I have 2 instances assigned to the App Service.  This week, the App Service shows about 60% CPU usage, and its usually about 10-15%.  Upon further investigation, it looks like 1 of the two instances is maxed out.  When opening up the Site Metrics per Instance, I can see that HTTP Response times are in the 1000s of milliseconds for one instance, and less than 200ms for the other.  I have tried restarting the W3P process on the offending instance, but that doesn't seem to help.  I have also tried scaling up to additional instances.  The new instances look good, but when I scale back down, the fabric won't kill the offending instance.</p>
  
  <p><strong>How can I force the fabric controller to kill off a specific instance?</strong></p>
  
  <p>I found the AzureRestartRole powershell command here (<a href="https://msdn.microsoft.com/en-us/library/azure/dn495202.aspx" rel="noreferrer">https://msdn.microsoft.com/en-us/library/azure/dn495202.aspx</a>), but my Azure Powershell Command Prompt doesn't seem to recognize the command, so I tried upgrading to Azure SDK 1.3 with the install-module command, but the 'AzureRestartRole' command isn't found.</p>
