Overview
Event Index
Displays the event index.
Event Type
Displays the event type.
Last time Sent
Displays the time that the event was
occurred and sent.

Statistics > RMON Alarm
The
RMON Alarms
screen allows you to record important
events and critical network problems. The RMON Alarm
and Event Control Tables are used together to define
specific criteria that will generate response events.
Alarms can be set to test data over any specified time
interval and monitor changing values, such as a statistical
counter reaching a specific value, or a statistic changing
by a certain amount over a set interval. Alarms can be set
to respond to either rising or falling thresholds.

Index
Indicates a specific alarm.
Interval (Sec.)
Defines the time interval in seconds over
which data is sampled and compared with the rising or
falling threshold.
Interface
The selected interface on the Switch
Counter
Selects the counter variables.
Sample Type
The method of sampling data, either
Absolute or Delta.
Startup Alarm
Indicates how the alarm is activated when
the variable is compared to the thresholds. This can be set
to Rising, Falling, and Rising or Falling.
Rising Threshold
An alarm threshold for the sampled
variable. If the current value is greater than or equal to
the threshold, and the last sample value was less than the
threshold, then an alarm will be generated. (After a rising
event has been generated, another such event will not be
generated until the sampled value has fallen below the
Rising Threshold and reaches the Falling Threshold.)
Falling Threshold
An alarm threshold for the sampled
variable. If the current value is less than or equal to the
threshold, then an alarm will be generated. (After a falling
event has been generated, another such event will not be
generated until the sampled value has risen above the
Falling Threshold and reaches the Rising Threshold.)
Rising Event
The index of the Event that will be used if a
rising alarm is triggered. If there is no corresponding entry
in the Event Control Table, or if this number is zero, then
no event will be generated.
Falling Event
The index of the Event that will be used if
a falling alarm is triggered. If there is no corresponding
entry in the Event Control Table, or if this number is zero,
then no event will be generated.
Owner
Defines the name of the person who created this
entry.
