# Logging level

By default, the logging level is set for the Spotfire Service for Python to provide informational progress.

In the custom.properties file, you can set the logging level through the property `loggingLevel`. The Spotfire Service for Python uses Log4J2-defined logging levels.

Level | Description
--- | ---
`ALL` | All levels are reported.
`TRACE` | Reports a finer-grained level of events than the `DEBUG` level.
`DEBUG` | Reports a fine-grained level of events. This setting is most useful when you are debugging problems with the service.
`INFO` | The default. Reports informational messages that highlight the progress of the Spotfire Service for Python, but at coarse-grained level.
`WARN` | Reports potentially harmful situations.
`ERROR` | Reports errors. These errors might still allow the Spotfire Service for Python to continue running.
`FATAL` | Reports only very severe errors that cause the Spotfire Service for Python to stop.
`OFF` | Turns off logging.
