This object specifies the number of samples to maintain in a local cache for later retrieval by a manager. Each monitor session displays accumulated, average, maximum, minimum, and last sample data through the adGenCSMMonitorCounterTable. If the manager wishes to collect a history of 'last' sample data, they can either contiually poll the adGenCSMMonitorCounterTable and save the last sample data, or they can specify that the monitor session should maintain a cache of previous intervals in the adGenCSMMonitorCounterHistoryTable and poll that table at a reduced frequency.
