Call tree - All threads merged
Merged call tree shows a top-down call tree of all applications threads merged together into single tree. The cumulative time and counts of the same methods called from different threads will be shown.
Profiler shows call tree in CPU tracing, sampling and asynchronous sampling modes. For call counting mode the tree is not available, because call stacks are not collected.
CPU call tree respects filter settings and collapse filtered methods. Filtered method are marked with non-filled arrow icon and there is <...> hyperlink which allows to expand hidden content. You can always undo unfiltering by using the Ctrl+Z shortcut or from popup menu.
The following actions are available in main application menu and in the popup menu:
- CPU | Method Merged Callees (Ctrl+M) - shows the method's merged callees.
- CPU | Method Back Traces (Ctrl+Shift+M) - shows the method's back traces.
- Tools | Open in IDE (F7) - opens method declaration in IDE editor. See IDE integration.
