The application module takes actions when the tracked object changes its state.
•
The following describes how a static route is monitored through collaboration.
NQA monitors the reachability to 192.168.0.88.
1.
When 192.168.0.88 becomes unreachable, NQA notifies the track module of the change.
2.
The track module notifies the state change to the static routing module
3.
The static routing module sets the static route as invalid.
4.
NOTE:

Supporting threshold monitoring
NQA supports threshold monitoring for performance parameters such as average delay jitter and packet
round-trip time. The performance parameters to be monitored are monitored elements. NQA monitors
threshold violations for a monitored element, and reacts to certain measurement conditions (for example,
sending trap messages to the network management server). This helps network administrators
understand the network service quality and network performance.
Monitored elements
1.
Table 9 describes the monitored elements and the NQA test types in which the elements can be
monitored.

Threshold types
2.
The following threshold types are supported:
average—Monitors the average value of monitored data in a test. If the average value in a test
•
exceeds the upper threshold or goes below the lower threshold, a threshold violation occurs. For
example, you can monitor the average probe duration in a test.
accumulate—Monitors total number of times the monitored data violates the threshold in a test. If
•
the total number of times reaches or exceeds a specific value, a threshold violation occurs.
• consecutive—Monitors the number of consecutive times the monitored data violates the threshold
since the test group starts. If the monitored data violates the threshold consecutively for a specific
number of times, a threshold violation occurs.
