Let it run for some time (e.g. 10-20 seconds), then kill it with `Ctrl+C`. To run an analysis that displays durations of callbacks over time, use [this Jupyter notebook](https://gitlab.com/ros-tracing/tracetools_analysis/blob/master/tracetools_analysis/analysis/callback_duration.ipynb), which should be under `ros2_ws/src/tracetools_analysis/tracetools_analysis/analysis/`.
