Summary Mode combines data from the multiple data rows normally generated into one or more rows. When multiple rows are condensed into a single row, the data is combined using the rules in the following table.
| For the following Mode … | Summary fields are combined by… |
|---|---|
| Count | summing the values from all the contributing rows. For example, the ResUsageSawt.FlowCtlCnt field provides the total number of times that the system entered flow control state from a non-flow control state.
|
| Max | taking the maximum value from all the contributing rows. In Summary Mode, the reported value for a Max field such as ResUsageSpdsk.ConcurrentWriteMax is the maximum value from all the rows that are combined into a single summary row. |
| Min | taking the minimum value from all the contributing rows. In Summary Mode, the reported value for a Min field, such as AvailableMin is the minimum value from all the rows that are combined into a single summary row. |
| Track | summing the values from all the contributing rows. In Summary Mode, the Track values from each row to be combined are summed together. For example, ResUsageSawt.FlowControlled is a track field so that in Summary Mode, all the AMP vproc rows are combined into a single row and the FlowControlled field will report the summed value from each of the AMP vproc rows. |
Summary Mode is applicable to all tables except ResUsageSpma and ResUsageSps. If the information for a row of a table is in Summary Mode, the SummaryFlag value is set to 'S'. If the row is being logged normally, the SummaryFlag value is set to 'N'.
