TRACE - A System Wide Diagnostic Tool

TRACE is a system-wide diagnostic tool that allows one to gather timing information with a minimal impact on application(s) performance. TRACE supports a variety of architectures under Linux and VxWorks. This utility instruments code easily and is controllable through the /proc file system. It has hooks to be built into a larger monitoring/alarming/debugging framework as well as supporting architecture-dependent features such as performance measurement counters or registers.
