■Store history before and after events for— when an event is logged, 3Com Network Director can store a monitoring history for the time period surrounding the event for the monitor(s) that caused the event to occur. This allows you to review the cause of the event in more detail at a later date. You may choose to fully disable the history for events, or may change the period of time for which 3Com Network Director stores the history. 3Com Network Director stores a 10-minute history before and after events by default.

See “Configuring the Storage of Monitoring History for Events” on page 360 for more information.

■Historical Reports — 3Com Network Director can log monitored data for all monitors and then use this data later to construct historical reports. This is the default behavior. You can disable this logging if you do not require historical reports.
