Overview#

QNX Momentics Application Profiler is a performance profiler for a single application. It provides statistical profiling for non-intrusive performance measurement, as well as deep and precise function instrumentation performance analysis, visualized with the Execution Time view and the annotated source editor. In addition, instrumented profiling also includes support for call graph information and call counts.

Using the Application Profiler, developers can target areas of highly used code for debugging, performance analysis, and optimization of "hot spots".

Features#

• Attaching the profiler to software currently running on the target
• A source code annotated editor to show which lines consume the most CPU
• CPU usage view for multiple processes and targets, as well as for shared libraries
• Profiler enabled launching configuration for end-to-end execution statistics
• Postmortem profiling and analysis
• A Call graph view
• A Sampling Information view with sortable columns
• Supports time marker and shows the time difference since the last mark
