How can statistics for all active ROS Topics be obtained?

Is there a way to display statistics for all active ROS topics in a system? By statistics I mean bandwidth usage, publishing rate, number of messages dropped, etc. I looked at "rostopic bw" and "rostopic hz" but they only display information for one topic at a time.

Seems generally useful. If there is not already a solution, you can probably fork a copy of rostopic and modify it to handle that.

Since ROS Indigo node statistics are available via:

rosparam set enable_statistics true (see http://wiki.ros.org/Topics#Topic_statistics)

A nice framework including rqt plugins is available on https://github.com/ROS-PSE/arni

That level of instrumentation is not build into the client libraries. rostopic works by subscribing to the topics. Depending on your system that sort of measurement will be overly burdensome for all topics. This is hopefully a feature we can integrate into ROS 2.0. When we begin brainstorming use cases please bring this up for that.
