Monitoring/ Debugging ROS snaps on Ubuntu Core over SSH

I mean I just don’t get any log outputs. The daemon and the complete software runs totally fine (confirmed by using it on our machine with the GUI). I can see the logs I’m looking for in /rosout_agg. They just don’t end up in the snap logs or output.

I’m still having the issue with snap logs not showing anything and just found this post from someone else having the same problem: Snap logs does not show the logs even though they are in journalctl?

So is journalctl -fu doing the same as snap logs? Do these commands actually read from a log file or catch the stdout and stderr output directly? I’m still searching this log file for my service.

PS: I’m not even really interested in saving the logs. I just need the “live” outputs from my daemon.
