End of Life

We have no end-of-life issues to discuss at this time.

A few API has been deprecated. New APIs have been added for later replacement. They will be removed for the 3.0 release for Oxygen.


Trace Compass comes with multipe built-in trace parsers for the following standard:

  • Common Trace Format (CTF)

    • Linux LTTng kernel traces

    • Linux LTTng-UST userspace traces which can come from proprietary software or open source eg. Mir, MariaDB, QEMU traces

    • Other traces in CTF, e.g. Linux Perf traces (CTF), Bare metal traces (CTF), Hardware traces (e.g. IEEE Nexus 5001 CTF conversion).

  • GDB traces for debugging

  • Best Trace Format for OSEK

  • The libpcap (PAcket CAPture) format, for network traces

Trace Compass provides a remote tracer control for LTTng Kernel and UST Tracers for configuring of trace sessions. It supports the MI versions 2.0 and 3.0.

For the integration of the command-line analysis Trace Compass is able to consume analysis results specified by the LTTng Analysis Machine Interface.
