Configuring the NQA statistics collection function
NQA groups tests completed in a time period for a test group, and calculates the test result statistics. The statistics form a statistics group. To view information about the statistics groups, use the display nqa statistics command. To set the interval for collecting statistics, use the statistics interval command.
When the number of statistics groups kept reaches the upper limit and a new statistics group is to be saved, the oldest statistics group is deleted. To set the maximum number of statistics groups that can be kept, use the statistics max-group command.
A statistics group is formed after the last test is completed within the specified interval. Statistics groups have an aging mechanism. A statistics group is deleted when its hold time expires. To set the hold time of statistics groups for a test group, use the statistics hold-time command.
Follow these guidelines when you configure the NQA statistics collection function:
The NQA statistics collection function is not supported in DHCP tests.
If you use the frequency command to set the frequency between two consecutive tests to 0, only one test is performed, and no statistics group information is collected.
