Displaying a List of RMON Events
RMON Events are actions that occur based on Alarm conditions detected by an RMON probe. To view a
list of logged RMON Events, enter the show rmon events command without specifying an entry number
for a particular probe, such as:
-> show rmon events
A display showing all logged RMON Events must appear, as shown in the following example:
Entry Time Description
---------+----------------+-----------------------------------------------------
1 00:08:00 etherStatsPkts.4008: [Falling trap] “Falling Event”
2 00:26:00 etherStatsCollisions.2008: “Rising Event”
3 00:39:00 etherStatsCollisions.2008: “Rising Event”
The display shown above identifies the Entry number of the specified Event, along with the elapsed time
since the last change in status (measured in hours/minutes/seconds) and a description of the Alarm
condition detected by the probe for all RMON Logged Events. For example, Entry number 3 is linked to
etherStatsCollisions.2008: [Rising trap] “Rising Event,” an Alarm condition detected by the RMON probe
in which a trap was generated based on a Rising Threshold Alarm, with an elapsed time of 39 minutes
since the last change in status.
Displaying a Specific RMON Event
To view information for a specific logged RMON Event, enter the show rmon events command,
specifying an entry number (event number) for a particular probe, such as:
-> show rmon events 3
A display showing the specific logged RMON Event must appear, as shown in the following example:
Entry Time Description
---------+----------------+-----------------------------------------------------
3 00:39:00 etherStatsCollisions.2008: “Rising Event”
The display shown above identifies the Entry number of the specified Event, along with the elapsed time
since the last change in status (measured in hours/minutes/seconds) and a description of the Alarm
condition detected by the probe for the specific RMON Logged Event. For example, Entry number 3 is
linked to etherStatsCollisions.2008: [Rising trap] “Rising Event,” an Alarm condition detected by the
RMON probe in which a trap was generated based on a Rising Threshold Alarm, with an elapsed time of
39 minutes since the last change in status.
