OpenTNF Tracing System
OpenTNF is a system-level tracing facility for
capturing and presenting diagnostic information and performance metrics. To use
OpenTNF, a developer first instruments one or more of the programs in a system
with ``probes''. The system is then run under the control of the `trex' (TRace
EXecution) command. Under trex control, data from the embedded probes is
captured by the OpenTNF kernel subsystem. The `tnfdump' command may then be used
to extract the captured data into a TNF (Trace Normal Form) file for subsequent
analysis.
OpenTNF is currently available for the following platform:
- Linux/Intel (kernel 2.2.x)
The OpenTNF project is seeking
developers for ports to other platforms. Note that some expertise in kernel
module or device driver development for the target platform is required. Other
contributions are also welcome. Email the developers if you're
interested in pitching in.
The current (Alpha) release of OpenTNF is available from our project page on SourceForge.
