Tracing and Debugging With the TNF Utilities

Although Dtrace, Performance Analyzer, Thread Analyzer, and dbx are more modern tools, you can also still use the older TNF utilities to trace, debug, and gather performance analysis information from your applications and libraries. The TNF utilities integrate trace information from the kernel as well as from multiple user processes and threads. The TNF utilities have long been included as part of the Solaris software. See the tracing(3TNF) man page for information about these utilities.
