PRTG Manual: WMI History
To open the WMI history view select a WMI monitor in the WMI monitor list and open 'WMI History' in the monitors context menu. The WMI history view contains a grid with the following details about the collected results.
The name of the WMI query.
The time the query was run.
The response to the WMI query from the WMI agent.
By default the history view will update as new monitor results are collected, providing a real-time view of the monitor results. If you would like to stop the refresh of the view to inspect the current results, un-check the "Show Latest State" check box.
