ROS Console is useful for changing the logging level for one or more nodes.
To see the current logging level for a node:
rosconsole get <NODE> <LOGGER>
The LOGGER parameter allows the user to choose specific logger messages to increase the level of. normally it is sufficient to use
ros.robosub as the logger unless you think there is a problem with ROS itself. In that case use
rosconsole set <NODE> <LOGGER>
rosconsole list <NODE>
