Server Application Monitor

Cause

This occurs when the monitor uses the wrong WMI path when performing the actual poll. As the WMI Query is being run locally, it should be using the path \\.\root\CIMV2 or \root\CIMV2

This is a known issue in SAM 6.2.3 or earlier.

Resolution

Upgrade to SAM 6.2.4, where this issue has been fixed. If you are unable to upgrade the application, perform the following workaround:

  1. On the Web Console, go to Settings > Manage Nodes.
  2. Select the node in question and click Edit Properties.
  3. Next to the Polling IP Address field , click Select IP Address.
  4. Choose an IP address other than the one the node is currently using.
  5. Click Submit.
