switching

I would like to monitor the the context switching behavior in a multi-threaded pthread application.

In other RTOSes(Micro C OS) I have been able to register a context switch callback for each thread in the application, and then log (or toggle a gpio) and watch the thread context switching in real time. This was a valuable tool for debugging the real time behavior and interaction of the multiple threads.

My current environment is embedded linux utilizing the pthread api. Is there a way to montior each of the context switches?
