Understanding RMON Events

An RMON event allows you to log the crossing of thresholds of other MIB objects. It is defined in eventTable for the RMON MIB.

This section covers the following topics:

eventTable

eventTable contains the following objects:

  • eventIndex—An index that uniquely identifies an entry in eventTable. Each entry defines one event that is generated when the appropriate conditions occur.
  • eventDescription—A comment describing the event entry.
  • eventType—Type of notification that the probe makes about this event.
  • eventCommunity—Trap group used if an SNMP trap is to be sent. If eventCommunity is not configured, a trap is sent to each trap group configured with the rmon-alarm category.
  • eventLastTimeSent—Value of sysUpTime when this event entry last generated an event.
  • eventOwner—Any text string specified by the creating management application or the command-line interface (CLI). Typically, it is used to identify a network manager (or application) and can be used for fine access control between participating management applications.
  • eventStatus—Status of this event entry.

    Note: If this object is not set to valid, no action is taken by the associated event entry. When this object is set to valid, all previous log entries associated with this entry (if any) are deleted.
