rqt_graph is the successor of rxgraph.

Topic statistics

New in ROS indigo

roscpp and rospy can measure certain statistics for every topic connection (see Topics for more details. This has to be enabled beforehand through:

$ rosparam set enable_statistics true

After that, rqt_graph will automatically annotate the ROS graph with statistics information.

Note: rqt_graph currently does not automatically update the statistics annotations. You have to hit the Refresh button to update them.


This is an example of rqt_graph with statistics measurement enabled:
