tracetools

Building

If tracing is not enabled when building, or if LTTng is not found, then this package will not do anything.

To enable tracing:

  1. Install LTTng: 
    $ sudo apt-get install lttng-tools lttng-modules-dkms liblttng-ust-dev
  2. Build with the WITH_LTTNG flag: 
    $ colcon build --cmake-args " -DWITH_LTTNG=ON"
  3. Check if tracing is enabled (after sourcing): 
    $ ros2 run tracetools tracetools_status

Tracing

By default, the steps above will not lead to trace data being generated, and thus they will have no impact on execution.

LTTng has to be enabled: TODO mention scripts
