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 steps to configure the NQA statistics collection function:
