Ros 2 monitor

How can we monitor ROS-2 nodes.?

How can we monitor ROS-2 nodes.?

The question as-is doesn’t provide enough information to give you a “good” answer. Can you please eloaborate what your are trying to do / want to achieve.

Moved to ROS2 category aka “Next Generation ROS”

I mean in order to monitor ros-1 we have ‘rqt_top’ command which can be executed in the command line to view the various phenomenons.
Similarly ,what command or is there any procedure to monitor in ros-2??
Is it clear enough???

rqt is not available in ROS 2 yet. Only command line tools to e.g. list running nodes is available (ros2 node list).

You could always resort to use top for process monitoring.
