Diagnostics not seen on local but seen on Robot (running ROS MASTER).
I am having problems with seeing published messages on the /diagnostics and /diagnostics_agg topics on my system. My system has a main robot that is running ROS MASTER and a laptop. I can ssh into the robot and can rostopic echo the topics the msgs. However, on my laptop side, a rostopic list shows the /diagnostics and /diagnostics_agg but with an echo, no messages are seen.
Other topics are viewable on my laptop side as well as on the robot. For example imu/data works for both robot and laptop. Therefore, the ROS_MASTER_URI and ROS_IP are set correctly. Only /diagnostics and /diagnostics_agg do not work.
Has anyone come across this issue?
