Pool History Report
The Pool History Report displays summary information for pool performance data when one of the three summary report option keywords, DAY, WEEK, or MONTH, is used. If none of the three summary report option keywords is used, the Pool History report displays snapshot data for the pool that is specified by the POOL report option keyword.
Note
The PERF_POOL report name verb can create two different reports: Pool History Report and Pool History Snapshot Report. The Pool History Report is generated when the POOL report option keyword is used with a complete pool name, while the Pool History Snapshot Report is generated when the SNAPSHOT report option keyword is used.

Field list for the Pool History Report
Column heading | Field name | Description |
|---|---|---|
Date Max | DATEMAX | The date of the snapshot in which the maximum IOs per second was found. |
Date Min | DATEMIN | The date of the snapshot in which the minimum IOs per second was found. |
Day | DAY | Day of the week. |
I/Os /sec Avg | IOSAVG | The IO operations per second average for the summarized snapshot samples. |
I/Os /sec HWM | IOSHWM | The IO operations per second high-water mark from the summarized snapshot samples. |
I/Os /sec LWM | IOSLWM | The IO operations per second high-water mark from the summarized snapshot samples. |
I/Os /sec Max | IOSMAX | The maximum IO operations per second found in the summarized snapshot samples. All shown maximum values are from the snapshot in which this value is found. |
I/Os /sec Min | IOSMIN | The time of the snapshot in which the minimum IOs per second was found. |
Intv Strt Date | DATE | The summarization interval starting date. |
Month | MONTH | The month of the year. |
Resp Time Avg | RESPTAVG | The response time in milliseconds average for the summarized snapshots. |
Resp Time HWM | RESPTHWM | The response time in milliseconds high-water mark from the summarized samples. |
Resp Time LWM | RESPTLWM | The response time in milliseconds low-water mark from the summarized snapshots. |
Resp Time Max | RESPTMAX | The maximum response time in milliseconds found in the summarized snapshot samples. All shown maximum values are from the snapshot in which this value is found. |
Resp Time Min | RESPTMIN | The minimum response time in milliseconds found in the summarized snapshot samples. All shown minimum values are from the snapshot in which this value is found. |
Samples | SAMPLES | The total number of snapshots in the interval. |
Time Max | TIMEMAX | The time of the snapshot in which the maximum IOs per second was found. |
Time Min | TIMEMIN | The time of the snapshot in which the minimum IOs per second was found. |
Vol Cnt Avg | VOLCAVG | The volume count average for the summarized snapshot samples. |
Vol Cnt HWM | VOLCHWM | The volume count high-water mark from the summarized snapshot samples. |
Vol Cnt LWM | VOLCLWM | The volume count low-water mark from the summarized snapshot samples. |
VOL CNT MAX | VOLCMAX | The number of volumes in a pool from the snapshot in which the maximum response time was found. |
VOL CNT MIN | VOLCMIN | The number of volumes in a pool from the snapshot in which the minimum response time was found. |
