Getting the system's status

The QNX Neutrino RTOS includes various utilities that you can use to fine-tune your system.

hogs: List the processes that are hogging the CPU
pidin (Process ID INfo): Display system statistics
ps: Report process status
top: Display system usage (Unix)

For details about these utilities, see the Utilities Reference.

For more detailed and accurate data, use tracelogger and the System Analysis Toolkit (see the SAT User's Guide). The SAT logs kernel events, the changes to your system's state, using a specially instrumented version of the kernel (procnto*-instr).

Note: If you have the Integrated Development Environment on your system, you'll find that it's the best tool for determining how you can improve your system's performance. For more information, see the IDE User's Guide.
