Configuring the NQA statistics collection feature
NQA forms statistics within the same collection interval as a statistics group. To display information
about the statistics groups, use the display nqa statistics command.
NQA does not generate any statistics group for the operation that runs once. To set the NQA
operation to run only once, use the frequency command to set the interval to 0 milliseconds.
To configure the NQA statistics collection feature:
