Viewing statistics for memory events

You can group memory events based on different data fields. The steps below demonstrate grouping events by allocation kind, but as explained later, you can group them by other fields.
To view statistics for memory events by allocation kind:
  1. In the Memory Events view, right-click and select Preferences… from the context menu.
  2. In the Preferences dialog, select the columns Expand, Kind, Average Size, Max Size, and Count, and deselect all of the other columns.
  3. Click OK.
  4. Right-click again, then select Group By > Kind.

Events are grouped by the allocation or deallocation kind, as shown here:
Memory event statistics by kind

The Count column shows the number of events in the group. The non-aggregated columns show the value of the first problem in the group.

Similar statistics based on the band size (i.e., the allocation size range) can be obtained by selecting Group By > Band Size, and then adding the Actual Size column using the Preferences dialog:
Memory event statistics by actual size

Statistics can also be obtained based on the backtrace field, by selecting Group By > Backtrace:
