Figure 15 Logging Tab
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"
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.
See "Performance Reporting" on page 385 for more information.
