[logback-user] How to disable logger output to one of its appenders

30 Nov 2021

      Hi all,

I have an "org.geotools" logger with 2 appenders, each appender directs the
output to a different file. This is the default configuration in my app.
The users have the possibility to override this configuration so maybe a
user wants to direct the output of this logger to only one file. It seems
that setting the level "OFF" to this logger for one appender doesn't have
any effect here, the loggings are still directed to both files (knowing
that additivity is set to false).

 appender("appender1", RollingFileAppender) {
        file = "${logDir}/Test.log"
        encoder(PatternLayoutEncoder) {
            charset = Charset.forName('UTF-8')
            pattern = log_pattern
        }
        rollingPolicy(FixedWindowRollingPolicy) {
            fileNamePattern = "${logDir}/Test%i.log"
            minIndex = 1
            maxIndex = 2
        }
        triggeringPolicy(SizeBasedTriggeringPolicy) {
            maxFileSize = FileSize.valueOf("20MB")
        }
    }
    appender("appender2", RollingFileAppender) {
        file = "${logDir}/stacktrace.log"
        encoder(PatternLayoutEncoder) {
            charset = Charset.forName('UTF-8')
            pattern = log_pattern
        }
        rollingPolicy(FixedWindowRollingPolicy) {
            fileNamePattern = "${logDir}/stacktrace%i.log"
            minIndex = 1
            maxIndex = 2
        }
        triggeringPolicy(SizeBasedTriggeringPolicy) {
            maxFileSize = FileSize.valueOf("20MB")
        }
    }

    logger("org.geotools", OFF, ['appender1'], false)
    logger("org.geotools", TRACE, ['appender2'], false)

What should I do to be able to  disable the logger only in one appender?

Thanks in advance!
