Tracing and Debugging With the TNF Utilities

Use the TNF utilities (included as part of the Solaris system) to trace, debug, and gather performance analysis information from your applications and libraries. The TNF utilities integrate trace information from the kernel and from multiple user processes and threads, and so are especially useful for multithreaded code.

With the TNF utilities, you can easily trace and debug multithreaded programs. See the TNF manual pages for detailed information on using prex(1) and tnfdump(1).
