Log

Authelia performs logging to various locations. This section describes how to configure and tune this.

The logging section tunes the logging settings.

Configuration #

log:
  level: info
  format: text
  file_path: ""
  keep_stdout: false

Options #

level #

Defines the level of logs used by Authelia. This level can be set to trace, debug, info, warn, or error. When setting level to trace, you will generate a large amount of log entries and expose the /debug/vars and /debug/pprof/ endpoints which should not be enabled in production.

log:
  level: debug

format #

Defines the format of the logs written by Authelia. This format can be set to json or text.

log:
  format: json

JSON format #

{"level":"info","msg":"Logging severity set to info","time":"2020-01-01T00:00:00+11:00"}
{"level":"info","msg":"Authelia is listening for non-TLS connections on 0.0.0.0:9091","time":"2020-01-01T00:00:00+11:00"}

Text format #

time="2020-01-01T00:00:00+11:00" level=info msg="Logging severity set to info"
time="2020-01-01T00:00:00+11:00" level=info msg="Authelia is listening for non-TLS connections on 0.0.0.0:9091"

file_path #

Logs can be stored in a file when file path is provided. Otherwise logs are written to standard output. When setting the level to debug or trace this will generate large amount of log entries. Administrators will need to ensure that they rotate and/or truncate the logs over time to prevent significant long-term disk usage.

If you include the value %d in the filename it will replace this value with a date time indicative of the time the logger was initialized using 2006-02-01T150405Z as the format.

File Path Examples #

Standard Example:

log:
  file_path: /config/authelia.log

Date Time Example:

log:
  file_path: /config/authelia.%d.log

keep_stdout #

Overrides the behaviour to redirect logging only to the file_path. If set to true logs will be written to both standard output, and the defined logging location.

log:
  keep_stdout: true
