Log4jmemes.com: for those of us that need a laugh
The one about using print/console.log/whatever lol.I've always done this, never have I used a library for this, because:  - running manually? >myapp.log 2>&1
  - using systemd? use journalctl
  - using docker/kubernetes? capture automatically the stdout/stderr of your containers and pipe them through logstash or something

Real question: why would an application need to know where its logs go? This is not in the business perimeter, but the ops perimeter. Am I wrong?EDIT:Most responses are about configuring logging level, output format, etc... This can be done with a print-based approach without sending a request to an external service (which would need to trust you and your inputs).Example: Python's default logging module.Still, thank you for your insightful answers :)
