Using the Call Tree tab

The Call Tree tab provides information about method calls during the profiling session in a form that lets easily identify a hot spot. It consists of two parts: the execution flow call tree and call stack view.

Before you begin

Launching or attaching to an application
In specifying profiling criteria, the Execution Time Analysis with Show execution flow statistics profiling set is enabled in a custom profiling set.

Display

Here is a sample of the Call Tree tab display: Method invocation tab showing three threads

The tree shows relative time spent in a method execution against total time spent in application run. The first-level items in the tree are threads instances. The tree items show the cumulative time of methods, and when expanded the base time of a method is shown as one of sub-items. The percentage column in the table is shown as the bar graph where 100% is the total time of the thread. Sorting by this column is available.

The call stack view shows the stack trace of the method selected in the call tree. The tree shows aggregated information while the stack trace can be ambiguous if one method is called from another several times at different lines of code. In this case the stack traces can be navigated by "previous" and "next" buttons. Cumulative time for every method in the stack trace is provided in absolute and percentage forms.
