journalctl. I don't give a damn as to where the logs are, and I just have tell journalctl to give me the logs for whatever I want.
Yeah but you can use journalctl on literally everything from binaries to units to cron jobs with the same interface. You don't need to find the log file just punch it into journalctl
It's like docker-compose on steroids if you don't use Kubenetes and want to treat your machines like pets not cattle
Sorry to tell you I never had a battery
