Ros2 node info does not show info for nodes of the same name #279
Description
It is possible to launch multiple nodes of the same name. When this happens, those multiple nodes show up in ros2 node list but it is impossible to get info on these nodes with ros2 node info.
In the below example, I have launched a single amcl process which spins up 3 nodes. But since the three nodes were assigned the same name, I can't introspect to see what topics those nodes are listening/publishing on.
$ ros2 node list
/KeystrokeListen
/launch_ros
/launch_ros
/launch_ros
/rover_serial
/ArrowsToTwist
/se_node
/bno055_driver
/rviz
/robot_state_publisher
/joint_state_publisher
/amcl
/rplidar_node
/amcl
/rover
/se_node/transform_listener_impl/transform_listener_impl
/amcl
$ ros2 node info /amcl
/amcl
