Configuring the NQA Statistics Function
NQA puts the NQA tests completed in a specified interval into one group, and calculates the statistics of
the test results of the group. These statistics form a statistics group. You can use the
display nqa
statistics
command to view information of the statistics group, and use the
statistics interval
command to set the interval for collecting statistics.
When the number of statistics groups kept reaches the upper limit, if a new statistics group is generated,
the statistics group that is kept for the longest time is deleted. You can use the
statistics max-group
command to set the maximum number of statistics groups that can be kept.
A statistics group is formed after the last test is completed within the specified interval. A statistics group
has the aging mechanism. A statistics group will be deleted after it is kept for a period of time. You can
use the
statistics hold-time
command to set the hold time of a statistics group.
