What it does

  • Provides tracing instrumentation (tracepoints) for the core ROS 2 packages.
  • Offers a `ros2 trace` CLI command and a launch file `Trace` action to configure and run tracing sessions.
  • Supports snapshot mode, which keeps trace data in memory and writes to disk only when a snapshot is taken.
  • Supports dual session tracing, separating initialization events in snapshot mode from runtime events.
  • Includes packages for LTTng Python bindings, reading traces, and tracing-related tests.
  • Trace analysis is handled by a separate project, tracetools_analysis.

Getting started

Difficulty
Advanced
Hardware it needs, as the project states it
Linux, since only the LTTng tracer is supported; the LTTng kernel tracer must be installed separately to trace kernel events.
