346 CHAPTER 8: THE EVENT LOG
If 3Com Network Director was not able to interpret the SNMP trap when
it was received then the main body of text will simply provide some
high-level information about the raw content of the trap.
If you know the format of an SNMP trap that 3Com Network Director is
unable to interpret then you may configure 3Com Network Director with
this information. 3Com Network Director will then be able to interpret
the trap if it receives it again. See Appendix F
for more information on
how to extend Network Director's default set of trap decodes.
Full details of the raw contents of the SNMP trap that a trap-based event
was generated for are available in the Trap Decode tab. See “
Trap Decode
Tab ” on page 348.
3Com Network Director internal events: For 3Com Network
Director internal events the content of the main body of text depends
upon the event itself, but will contain details of the reason for the event
and any other pertinent information.
For monitor-based and SNMP trap-based events the Events tab also
shows details of the number of events generated by this monitor in the
last day and the last week below the main body of text and, for
monitor-based events, shows details of the absolute value of, and the
threshold that was configured for, the monitor when the event was
generated.
As well as providing details of the selected event, the Event tab also
allows you to control the generation of the event via the Change
Thresholds and Disable this Event buttons. See “
Setting Thresholds for
Monitor-Based Events” on page 356 and “Disabling and Enabling
Events” on page 349 respectively for more information.
Graphs Tab
The Graphs tab is only visible when you are viewing details for a
monitor-based event, and provides a historical graph of the monitoring
state around the time that the event was generated:
