Features

A few customized scripts will be made available, some built-in and others ready for download. For the present release, only the Call Graph script will be pre-bundled.

Call Graph

Renders a visual function trace of the program, tracking selected or all functions.


This feature comes with a few different display options and various other information such as the percentage time spent in a function and the number of times a function is called. All of these settings can be changed and accessed through the SystemTap view menu.

The following types of views are available to see the call hierarchy of the functions belonging to the executable.

The graph itself is linked to the CDT -- hold CTRL and double-click any function in a non-aggregate view to be taken to where that function was called. Doing the same for an aggregate node will take you to where that function is defined.
