Description
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 when the following conditions are met:
•
The current sampled value is greater than or equal to this threshold.
•
The value at the previous sampling interval was less than this threshold.
A rising alarm will also be generated when the following conditions are met:
•
The first sample after this entry becomes valid is greater than or equal to
this threshold.
•
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 when the following conditions are met:
•
The current sampled value is less than or equal to this threshold
•
The value at the previous sampling interval was greater than this
threshold.
A falling alarm will also be generated when the following conditions are met:
•
The first sample after this entry becomes valid is less than or equal to this
threshold.
•
The associated alarmStartupAlarm is equal to fallingAlarm or
risingOrFallingAlarm.
Alarm that can be generated when the entry becomes valid (MIB object
alarmStartupAlarm):
•
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.
Most recent sampled value (MIB object alarmValue).
