The Pool activity section of the Pool interval report displays the performance information on the storage pools at various time intervals.
One line is printed for each active pool that existed during each selected interval. Changes to this section of the report include:

Itv End -- Interval end time (hour and minute)
PL -- Pool identifier Act Lvl -- Activity level of the pool Size (GB) -- Size of the pool (Gigabytes)
CPU Util -- Average CPU utilization by the transactions in the pool. This is the average of all processors Tns -- Number of transactions in the pool Physical I/O per Trans -- Average physical disk I/O operations per transaction in the pool Synchronous DBR -- Average synchronous data base reads per transaction Synchronous DBW -- Average synchronous data base writes per transaction Synchronous NDBR -- Average synchronous non-data base reads per transaction Synchronous NDBW -- Average synchronous non-data base writes per transaction
Asynchronous DBR -- Average asynchronous data base reads per transaction Asynchronous DBW -- Average asynchronous data base writes per transaction
Asynchronous NDBR -- Average asynchronous non-data base reads per transaction Asynchronous NDBW -- Average asynchronous non-data base writes per transaction Job Maximums -- Maximum values by a job in the pool CPU Util -- Highest percentage CPU utilization Phy I/O -- Most physical disk I/O requests
Tns -- Most transactions Rsp -- Highest average response time (seconds)
A-W -- Most active-to-wait transitions W-I -- Most wait-to-ineligible transitions A-I -- Most active-to-ineligible transitions
