Configuration to filter rosnodes and rostopics for rosout without using GUI

edit

Hello,

I have a requirement where in I need to log only certain ROS messages from the nodes that I have in my ROS environment ignoring the rest as I have a limitation of memory and usability. I will not be having any visual interface once I have my ROS started with my application and I would like to log messages of only the nodes/topics that I would be providing in my configuration file.

May I know if we can edit the existing python_logging.conf or rosconsole.config for my purpose ? I have both cpp and python projects.

I'm using ROS melodic.

TIA
