Command

Usage

Index

Displays the index number that identifies each alarm instance.

Interval

Displays the time interval over which data is sampled and compared with the rising and falling

 

thresholds.

Type

Displays the method of sampling the selected variable and calculating the value to be compared

 

against the thresholds, as follows:

 

abs: absolute value, the value of the selected variable is compared directly with the thresholds at

 

the end of the sampling interval.

 

delta: delta value, the value of the selected variable at the last sample is subtracted from the current

 

value, and the difference compared with the thresholds.

rLimit

Displays the rising threshold for the sampled statistic.

fLimit

Displays the falling threshold for the sampled statistic.

rEvtIdx

Displays the rising alarm event index that is triggered when a rising threshold is crossed.

fEvtIdx

Displays the falling alarm event index that is triggered when a falling threshold is crossed.

Last value

Displays the last sampled value.

OID

Displays the MIB Object Identifier for each alarm index.
