Cause

  • AppInsight for IIS was first configured to work on remote monitoring when the server was still on WMI polling method
  • Invalid credential assigned to the application

Resolution

Disable AppInsight for IIS under List Resources
  1. Go to Manage Nodes
  2. Tick the affected server
  3. Click List Resources
  4. Uncheck AppInsight for IIS
  5. Hit Submit
Re-enable AppInsight for IIS
  1. Run another List Resources on the affected server
  2. Click 'Force Refresh' if prompted
  3. Check AppInsight for IIS
  4. Hit Submit

If receiving the Access is Denied message then you should
  • Attempt assigning a different credential to the application monitor
or
  • Change the credential to 'inherit from node' to use the local system account to poll the application data.
