346CHAPTER 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:
