performance evaluation of callbacks

asked 2018-12-06 05:01:11 -0500

Hi there,

I was wondering about how to measure the performance in terms of execution time per sec of a specific callback (from a topic subscription or service). Does anyone know if ROS provide such a "feature" ? I'd like to avoid reinventing the wheel :-)

Bests, Augusto

I don't know of a specific feature for timing callback functions but you should be able to record the time using ros::Time::now() at the beginning and end of the function. Subtracting one from the other will give you the duration of the callback execution.

This will not give you the timing of the message passing system though, just the callback function itself.
