View or Suppress Logback Status

Logback always shows status statements if there are configuration errors

Logback will log its own status statements to the console if you have any configuration problems resulting in WARN or ERROR messages, which will also show INFO messages. The Logback levels are, from lowest level to highest level:

TRACE < DEBUG < INFO < WARN < ERROR

(See Logback Architecture: error levels for details.)

See Logback status statements

To see Logback's status statements in the console (standard out) regardless of whether or not there are any configuration errors, set the debug attribute to true in the configuration element.

  <configuration debug="true">
    ...
  <configuration>

Suppress Logback status statements

To suppress display of Logback's status statements to the console, omit the debug attribute in the configuration element or set it to false. This will not suppress status statements if there are configuration problems with Logback.

  <configuration>
    ...
  </configuration>

If there is no debug attribute or it's set to false and you see Logback status statements, fix the problems causing the WARN or ERROR statements and the statements will no longer display.

If you can't fix the configuration problem but want to suppress the status statements, you can configure an alternate StatusListener like NopStatusListener to completely remove status statements.

  <configuration>
    <statusListener class="ch.qos.logback.core.status.NopStatusListener" />
    ...
  </configuration>
