[ros-users] [Discourse.ros.org] [Next Generation ROS] Diagnostic-aggregator and diagnostic-updater porting to ROS2

[v-lopez]

We have always used the diagnostics not only for monitoring hardware, but also software behavior. 
You can monitor the tf topic frequency in the same way you monitor a camera topic. 

In that sense hardware_id has been something inconvenient, I don't know if it makes sense for ROS2 to rename it to something more generic.
