Change between 32-bit and 64-bit polling

You should use 64-bit polling on 64-bit OS systems. Using AppInsight applications with 32-bit polling on 64-bit computers via an agent prevents certain performance counters from collecting information.

You may need to log in with an administrator account to perform these changes.

Change to 64-bit polling at the application level:

  1. On the Web Console, click My Dashboards > Applications > SAM Summary.
  2. Select an AppInsight Application (Exchange, SQL, IIS) and then click Edit Application Monitor.
  3. Expand Advanced, and then click Override Template.
  4. In the Platform to run polling job field, change the value to x64.
  5. Click Submit.

Change to 64-bit polling at the template level:

  1. On the Web Console, click Settings > All Settings > SAM Settings > Manage Templates.
  2. Select an AppInsight application and click Edit.
  3. Expand Advanced, and in the Platform to run polling job on field, change the value to x64.

  4. Click Submit.
