Specifying Threshold Units
You can specify the units used to determine whether a variable has exceeded a
threshold.
To generate a threshold event when the variable’s rate of change per second
reaches one of the three thresholds, set the Threshold Units parameter to
Persecond.
To generate a threshold event when the value of the variable reaches one of
the three thresholds, set the Threshold Units parameter to Absolute.
Determining When to Record Threshold Events
You can determine when the agent generates a threshold event by setting the
Threshold Action parameter.
By default, the agent generates a threshold event when the value of the variable
you specify is greater than the threshold you specify. If you want the agent to
generate threshold events when the value of the variable is less than the threshold
you specify, set the Threshold Action parameter to Lessthan.
Specifying Maximum Successive Alarms
A maximum successive alarm represents two or more polling periods when the
agent generates an alarm as a result of an exception at the same threshold level.
You can specify an integer to determine the maximum number of successive
alarms that the agent generates for a variable. When the agent exceeds the
maximum number of alarms, it marks the threshold as held. The agent generates
no more alarms until the variable either crosses the threshold at a different level or
crosses no threshold for the number of polling intervals equal to the value of the
Threshold HoldDown Intervals parameter.
