Configuring the NQA statistics collection function
NQA collects statistics for operations completed within a specific period. The statistics forms a statistics
group. A statistics group is generated after an operation is completed. To view information about the
statistics groups, use the display nqa statistics command.
A statistics group is deleted when its hold time expires. When the maximum number of statistics groups
is reached, to save a new statistics group, the oldest statistics group is deleted.
If you use the frequency command to set the interval between two consecutive operations to 0, only one
operation is performed and no statistics group information is generated.
