System Profiler

The QNX System Profiler perspective displays kernel event trace data. Through an interactive editor, you can see different aspects of the kernel activity and select a time range of events to examine in detail. There are also several views that list helpful information such as the order of events, thread state event statistics, and runtimes for client and server threads.

To see data, you must first run a kernel event trace, which you can do from the IDE or command line. The System Profiler reads kernel event log (.kev) files generated during traces. The sections that follow describe how to use specific editor panes and views within the perspective to find certain events and understand what the trace is telling you.
