# Server Logging

> Logging configuration and output for the Merlin Server

<Note>
  The Server typically requires administrative privileges so that it can bind to an interface and TCP port.
  The log file will be created with the permissions of the user that started the Merlin Server.
</Note>

The Merlin Server creates a log file in the `data/log` directory called `merlinServerLog.txt` and **ALSO** writes
messages to STDOUT where the server was executed. The default logging level is `INFO`. Use the `debug`, `trace`,
and `extra` flags to enable more verbose logging.
