Configuring threshold monitoring
Threshold types
An NQA operation supports the following threshold types:
•
average
—If the average value for the monitored performance metric either exceeds the upper
threshold or goes below the lower threshold, a threshold violation occurs.
•
accumulate
—If the total number of times that the monitored performance metric is out of the
specified value range reaches or exceeds the specified threshold, a threshold violation occurs.
•
consecutive
—If the number of consecutive times that the monitored performance metric is out of the
specified value range reaches or exceeds the specified threshold, a threshold violation occurs.
Threshold violations for the average or accumulate threshold type are determined on a per NQA
operation basis, and threshold violations for the consecutive type are determined from the time the NQA
operation starts.
Triggered actions
The following actions might be triggered:
•
none
—NQA displays results only on the terminal screen. It does not send traps to the NMS.
•
trap-only
—NQA displays results on the terminal screen, and meanwhile it sends traps to the NMS.
•
trigger-only
—NQA displays results on the terminal screen, and meanwhile triggers other modules
for collaboration.
The DNS operation does not support the action of sending trap messages.
Reaction entry
In a reaction entry, a monitored element, a threshold type, and an action to be triggered are configured
to implement threshold monitoring.
The state of a reaction entry can be invalid, over-threshold, or below-threshold.
•
Before an NQA operation starts, the reaction entry is in invalid state.
•
If the threshold is violated, the state of the entry is set to over-threshold. Otherwise, the state of the
entry is set to below-threshold.
