Consider 3 levels per Ben's comment here #26 (comment).

A nice to have would be a way to bring logs into grafana.

#26 has been merged which has quite a few changes for logging.

/var/log/wlanpi_core/debug/debug.log is in JSON format which should be easy to ingest into grafana.

@bentumbler what do you think about changing the log format for /var/log/wlanpi_core/app.log to match? right now they're different.

A good idea for the backlog but as we are unlikely to implement anything to consume the logs anytime soon shall we just freeze where we are now for continued testing and pick this back up after WLPC.
Significant testing of the api starts on Saturday so if you do want to do something sooner then maybe target cop Friday for feature freeze
