Server logs
Within the c2 container, you will find a /data/logs directory with three log files:
access.log: This is a raw log of authenticated vs unauthenticated requests to your API endpoints on the C2.error.log: Errors which occurred on the C2 are logged here.login.log: Logs login attempts. The password is not logged for successful logins, however unsuccessful logins will have the password logged.
Please note: that there is no automatic log rotation; so these could grow (particularly access.log). If space is a concern, you should set up logrotate. This is a planned default feature from v0.6 onwards.
