RMON Alarm
In this table overview, every valid entry will be listed in the same page to help user to get the overview image on each control entry setting.
Index
Indicates the alarm entry index value.
Interval(Second)
The interval in seconds over which the data is sampled
and compared with the rising and falling thresholds.
Source Interface
Indicates the port number
Counter/Variable
Indicates which etherStatistics counter per interface been
assigned for alarm. The value might be (Unassigned) if the alarm entry is created but no
variable been configurred and the value might be (ohter) if the value
is assigned already but not in etherStatistics table with valid
interface.
Sample Type
Indicates the method of sampling the selected variable and
calculating the value to be compared against the thresholds.
Value
Indicates The value of the statistic during the last sampling
period. And this value is for comparing the risingThreshold and
fallingThreshold.
StartUp Alarm
Indicates the alarm that may be sent when this entry is first
set to valid.
RisingThreshold
Indicates a threshold for the sampled statistic.
FallingThreshold
Indicates a threshold for the sampled statistic.
RisingEventIndex
Indicates the index of the eventEntry that is used when
a rising threshold is crossed. The eventEntry identified by a
particular value of this index is the same as identified by the same
value of the eventIndex object. If there is no corresponding entry in
the eventTable, then no association exists. In particular, if this value is zero, no associated event will be
generated, as zero is not a valid event index.
FallingEventIndex
Indicates the index of the eventEntry that is used when
a falling threshold is crossed. The eventEntry identified by a
particular value of this index is the same as identified by the same
value of the eventIndex object. If there is no corresponding entry in
the eventTable, then no association exists. In particular, if this value is zero, no associated event will be
generated, as zero is not a valid event index.
Owner
Indicates the entry creator.

[RFC 2819]:
-- The Alarm group periodically takes statistical samples from
-- variables in the probe and compares them to thresholds that have
-- been configured. The alarm table stores configuration
-- entries that each define a variable, polling period, and
-- threshold parameters. If a sample is found to cross the
-- threshold values, an event is generated.
