Retrieving External WMI Cache Events
You can use Windows Management Instrumentation (WMI) to receive the internal cache events generated by the server. The WMS WMI Event Handler plug-in must be enabled, and you must specify that the server must register the cache event class. The following table identifies the WMI subevents that are raised when the server raises cache proxy events.
