Description
Alarm entry owner and status:
entry-number—Alarm entry index (MIB object alarmIndex).
owner—Entry owner (MIB object alarmOwner).
status—Entry status (MIB object alarmStatus):
VALID—The entry is valid.
UNDERCREATION—The entry is invalid.
The status field is not configurable at the CLI. All alarm entries created from the
CLI are valid by default.
The display rmon alarm command can display invalid entries, but the display
current-configuration and display this commands do not display their settings.
Sample type (MIB object alarmSampleType):
absolute—RMON compares the value of the variable with the rising and
falling thresholds at the end of the sampling interval.
delta—RMON subtracts the value of the variable at the previous sample from
the current value, and then compares the difference with the rising and falling
thresholds.
Monitored variable (MIB object alarmVariable).
Interval (in seconds) at which data is sampled and compared with the rising and
falling thresholds.
The MIB object for this field is alarmInterval.
Alarm rising threshold (MIB object alarmRisingThreshold).
A rising alarm will be generated if the current sampled value is greater than or
equal to this threshold, and the value at the previous sampling interval was less
than this threshold.
A rising alarm will also be generated if the first sample after this entry becomes
valid is greater than or equal to this threshold and the associated
alarmStartupAlarm instance is equal to risingAlarm or risingOrFallingAlarm.
Event index (EventEntry) associated with the alarm:
MIB object alarmRisingEventIndex stores the event index that is used when the
rising threshold is crossed.
MIB object alarmFallingEventIndex stores the event index that is used when
the falling threshold is crossed.
Alarm falling threshold (MIB object alarmFallingThreshold).
A falling alarm will be generated if the current sampled value is less than or
equal to this threshold, and the value at the previous sampling interval was
greater than this threshold.
A falling alarm will also be generated if the first sample after this entry becomes
valid is less than or equal to this threshold, and the associated
alarmStartupAlarm is equal to fallingAlarm or risingOrFallingAlarm.
