In ros1, it was possible to subscribe to /statistics which is of type TopicStatistics http://docs.ros.org/api/rosgraph_msgs...
Is this message & topic available in ros2? I dont see it listed under ros2 rcl interfaces https://github.com/ros2/rcl_interface...
I also see that the ros2 demo for topic monitoring has a different implementation https://github.com/ros2/demos/blob/ma...
No, we have neither that feature nor that message yet in ROS 2. We definitely should implement it, as it is a very useful feature in ROS 1, but we just haven't gotten around to it yet.
It would be great to have an issue to track this feature (maybe on https://github.com/ros2/ros2/ since it will span C++, Python, and tooling) and even better would be a pull request :)
Thanks for your feedback William I've opened a feature request as you suggested: https://github.com/ros2/ros2/issues/744 Perhaps if time permits will definitely look into contributing to it

Found another post that seems to indicate the same thing - absence of message TopicStatistics in ros2 https://answers.ros.org/question/3242...
