README

tracetools

The tracetools library is an Open Source project that provides tracing functions for message-passing middleware, specifically ROS.

Intended use

The intended use of this software is for collecting data from robotic systems during development.

The software is not targeted at use during production and has not been tested for this purpose. However, the license conditions of the applicable Open Source licenses allow you to adapt the software to your needs. Before using it in a safety relevant setting, make sure that the software fulfills your requirements and adjust it according to any applicable safety standards.

Instructions for use

This is a regular catkin package and can just be dropped into your workspace as-is.

Then either call the ros::trace methods directly, or use our modified ros_comm version.

However, to actually generate tracing output, you need to

  1. Install LTTNG using (example for Ubuntu) $ sudo apt install liblttng-ust-dev lttng-tools lttng-modules-dkms
  2. Pass WITH_LTTNG (example for catkin tools) $ catkin config -DWITH_LTTNG=ON
  3. Recompile your workspace
  4. TEST tracing with the included test script $ rosrun tracetools tracetools_test In this case, "no news is good news". If a problem occurs, the script will let you know.

At runtime, LTTng is not active by default (so you can leave it in your programs with no impact). To collect trace data, you need to start an LTTng session. In this package, in setup-lttng-roscpp.sh, a simple configuration script is included.

For even easier usage, with automatic data conversion, check out the tracetools_analysis package. It provides a Python API for easy definition, execution and analysis of tracing experiments.
