The script will trace the process based on pid/name and print the scheduler switches happening with the process. If no arguments are passed, it displays all the scheduler switches. This can be used to understand which tasks schedule out the current process being traced, and when it gets scheduled in again.</p></li> <li><a href="profiling/thread-times.stp">profiling/thread-times.stp</a> - Profile kernel functions<br> keywords: <a href="keyword-index.html#PROFILING">PROFILING</a> <br> <p>The thread-times.stp script sets up time-based sampling.
