How to Log connections

Hi, How can I log ROS TCP connection creations and destructions? I'm trying to move all my clients to persistent connections to avoid recreating too many TCP sockets (to avoid they dangle for a couple of minutes), but I still have many TIME_WAIT connections (for which I cannot see to which process they belong with netstat nor lsof -i)

Maybe enabling logs for roscore? We have diamondback but we're migrating soon to electric.

thanks

Maybe it helps to set the loggerlevel of roscpp or similar to DEBUG.

Not sure if it helps, but rosnode info shows all open socket connections. The implementation uses an xmlrpc call that you could maybe also use to poll open connections. Not really nice though...
