  • Added icons for analyses and views
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.

Standards

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.

Communities

  • Bugzilla has been used for planning and bug tracking

  • Centralized update site and download page for the standalone RCP

  • Trace Compass is part of the PolarSys solutions

  • Strong relationship with the LTTng project. Project members interact with this community via mailing list (lttng-dev@lists.lttng.org).

  • Many interactions with the CDT project. One committer is also committer in CDT.

  • Trace Compass has been the preferred Trace Analysis Tool for students as part of the trace research projects with the Polytechnique Montreal university. Many new features and enhancements for Trace Compass have been a direct outcome of  the reseach projects. See below for a link to the current active research track:
