The following describes how a static route destined for 192.168.0.88 is monitored through collaboration: 1. NQA monitors the reachability to 192.168.0.88. 2. When 192.168.0.88 becomes unreachable, NQA notifies the Track module of the change. 3. The Track module notifies the static routing module of the state change. 4. The static routing module sets the static route as invalid according to a predefined action. For more information about collaboration, see High Availability Configuration Guide. Threshold monitoring Threshold monitoring enables the NQA client to display results when the performance metrics that an NQA operation gathers violate the specified thresholds.

The following describes how a static route destined for 192.168.0.88 is monitored through collaboration:
1.
NQA monitors the reachability to 192.168.0.88.
2.
When 192.168.0.88 becomes unreachable, NQA notifies the Track module of the change.
3.
The Track module notifies the static routing module of the state change.
4.
The static routing module sets the static route as invalid according to a predefined action.

Threshold monitoring
Threshold monitoring enables the NQA client to display results when the performance metrics that an
NQA operation gathers violate the specified thresholds.
Table 13
describes the relationships between performance metrics and NQA operation types.
