# Overview

The Eclipse Callgraph plug-in provides a visual function trace of a program. This allows you to view a visualization of selected (or even all) functions used by the profiled application.

This plug-in allows you to profile C/C++ projects directly within the Eclipse IDE, providing various runtime details such as:

- The relationship between function calls
- Number of times each function was called
- Time taken by each instance of a function (relative to the program's execution time)
- Time taken by all instances of a function (relative to program's execution time)

Eclipse Callgraph uses SystemTap to perform function traces. For more information about SystemTap, refer to the SystemTap Beginner's Guide.
