Unique identifier for an entry in the alarm table. Each entry defines a diagnostic sample at a particular interval for an object on the device.
Interval, in seconds, over which the data is sampled and compared with the rising and falling thresholds.
Be careful setting this variable when using delta value sampling. The interval should be set short enough so that the sampled variable is unlikely to increase or decrease by more than 2^31 - 1 during a single sampling interval.
Note: This object may not be modified if the associated alarmStatus object is equal to "valid(1)".
Identifier of the particular variable to be sampled. Only variables that resolve to an ASN.1 primitive type of INTEGER (INTEGER, Counter, Gauge, or TimeTicks) may be sampled.
During a set operation, if the supplied variable name is not available in the selected MIB view, a badValue error is returned. If at any time the variable name of an established alarmEntry is no longer available in the selected MIB view, the probe changes the status of this alarmEntry to "invalid(4)".
Note: This object may not be modified if the associated alarmStatus object is equal to "valid(1)".
The method used for sampling the selected variable and calculating the value to be compared against the thresholds. If the value of this object is "absoluteValue(1)", the value of the selected variable is compared directly with the thresholds at the end of the sampling interval. If the value of this object is "deltaValue(2)", the value of the selected variable at the last sample is subtracted from the current value, and the difference is compared with the thresholds.
Note: This object may not be modified if the associated alarmStatus object is equal to "valid(1)".
The value of the statistic during the last sampling period. For example, if the sample type is "deltaValue", this value will be the difference between the samples at the beginning and end of the period. If the sample type is "absoluteValue", this value will be the sampled value at the end of the period.
This is the value that is compared with the rising and falling thresholds. The value during the current sampling period is not made available until the period is completed and will remain available until the next period completes.
The alarm that may be sent when this entry is first set to valid. If the first sample after this entry becomes valid is greater than or equal to the risingThreshold and alarmStartupAlarm is equal to "risingAlarm(1)" or "risingOrFallingAlarm(3)", then a single rising alarm is generated. If the first sample after this entry becomes valid is less than or equal to the falling Ttreshold and alarmStartupAlarm is equal to "fallingAlarm(2)" or "risingOrFallingAlarm(3)", then a single falling alarm is generated.
Note: This object may not be modified if the associated alarmStatus object is equal to "valid(1)".
Rising Threshold (alarmRisingThreshold)
A threshold for the sampled statistic. When the current sampled value is greater than or equal to this threshold, and the value at the last sampling interval was less than this threshold, a single event is generated. A single event is also generated if the first sample after this entry becomes valid is greater than or equal to this threshold and the associated alarmStartupAlarm is equal to "risingAlarm(1)" or "risingOrFallingAlarm(3)".
After a rising event is generated, another such event will not be generated until the sampled value falls below this threshold and reaches the alarmFallingThreshold.
Note: This object may not be modified if the associated alarmStatus object is equal to "valid(1)".
Falling Threshold (alarmFallingThreshold)
A threshold for the sampled statistic. When the current sampled value is less than or equal to this threshold, and the value at the last sampling interval was greater than this threshold, a single event is generated. A single event is also 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(2)" or "risingOrFallingAlarm(3)".
After a falling event is generated, another such event will not be generated until the sampled value rises above this threshold and reaches the alarmRisingThreshold.
Note: This object may not be modified if the associated alarmStatus object is equal to "valid(1)".
Rising Event Index (alarmRisingEventIndex)
Index of the eventEntry used when a rising threshold is crossed. The eventEntry identified by a particular value of this index is the same as the eventEntry identified by the same value of the eventIndex object. If there is no corresponding entry in the eventTable, then no association exists. In addition, if the value of this object is zero, no associated event is generated because zero is not a valid event index.
Note: This object may not be modified if the associated alarmStatus object is equal to "valid(1)".
Falling Event Index (alarmFallingEventIndex)
Index of the eventEntry used when a falling threshold is crossed. The eventEntry identified by a particular value of this index is the same as the eventEntry identified by the same value of the eventIndex object. If there is no corresponding entry in the eventTable, then no association exists. In addition, if the value of this object is zero, no associated event is generated because zero is not a valid event index.
Note: This object may not be modified if the associated alarmStatus object is equal to "valid(1)".
