Description
Sample type (MIB object hh3cRmonExtAlarmSampleType):
•
absolute—RMON compares the calculation result of the variable
formula with the rising and falling thresholds at the end of the sampling
interval.
•
delta—RMON subtracts the calculation result of the variable formula for
the previous sampling interval from the current calculation result, and
then compares the difference with the rising and falling thresholds.
Variable formula (MIB object hh3cRmonExtAlarmVariable).
Description of the alarm entry (MIB object hh3cRmonExtAlarmSympol.
Interval (in seconds) at which data is sampled and compared with the
rising and falling thresholds.
The MIB object for this field is hh3cRmonExtAlarmInterval.
Alarm rising threshold (MIB node hh3cRmonExtAlarmRisingThreshold).
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
hh3cRmonExtAlarmStartupAlarm instance is equal to risingAlarm or
risingOrFallingAlarm.
Alarm falling threshold (MIB object hh3cRmonExtAlarmFallingThreshold).
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
hh3cRmonExtAlarmStartupAlarm instance is equal to fallingAlarm or
risingOrFallingAlarm.
Event index associated with the alarm:
•
MIB object hh3cRmonExtAlarmRisingEvtIndex stores the event index
that is used when the rising threshold is crossed.
•
MIB object hh3cRmonExtAlarmFallingEvtIndex stores the event index
that is used when the falling threshold is crossed.
Alarm that can be generated when the entry becomes valid (MIB object
hh3cRmonExtAlarmStartupAlarm):
•
risingAlarm—Generates a rising alarm if the first sample after the entry
becomes valid is greater than or equal to the rising threshold.
•
fallingAlarm—Generates a falling alarm if the first sample after the
entry becomes valid is less than or equal to the rising threshold.
•
risingOrFallingAlarm—Generates a rising alarm or falling alarm if the
first sample after the entry becomes valid crosses the rising threshold or
falling threshold.
The default is risingOrFallingAlarm.
