I want to check whether the costmap gets updated or not at a fixed frequency. How can this be done in ROS ?

To view the frequency of a topic that is being publish, you can run rostopic hz topic_name. So in your case, depends on what kind of costmap you want to check the frequency, you can run something like

rostopic hz /move_base/local_costmap/costmap

Thank You for answering. However I wanted to know the method to check whether the costmap is really getting updated or not. I did not want to know the frequency.
