How do you create a log of published messages?

I'm completely new to robotics and software as a hobby. I've got my robot up and running and I'm trying to create a log file for specific messages in "create_autonomy".

I'm hoping to log this once a minute in the terminal window or a .txt file

hour:minute:second battery/charge (95%)
hour:minute:second joint_states (forward, 1.5 mph)

Any ELI5 help would be awesome, I'm not sure where to start

You could either simply modify the driver to log that information with a ROS_LOG_THROTTLE set at 1 second when you publish that information or create another ROS node to subscribe to that information with the same log.
