Grouping Levels (Granularities)
Each row in the Wakelocks pane corresponds to a grouping level (granularity). The main available grouping levels are Kernel Wakelock, Locking Process, Application Name, User Wakelog Tag, and combinations of these groupings in different order. You can change the grouping level using the Grouping drop-down menu at the top of the CWakelocks pane.
Click the plus sign
