Requirement is to change the log level for a specific user . Using DynamicThresholdFilter at the context level does work but applies to all the loggers . My requirement is to only apply it for specific loggers and not impact the others. With this configuration file all the appenders are logging at debug levell.

This is how my file looks like . Any recommendations on applying the same filter or any other filter which can enable debug logging for specific loggers ?

I tried applying the same filter at the appender level but it did not work

<RollingFile name="customLoggingAppender" fileName="${sys:log_dir}/customLogging.log" filePattern="customLogging-%d{yyyy-MM-dd}-%i.log" append="true">             <DynamicThresholdFilter key="customLogging-enabled" onMatch="ACCEPT" onMismatch="DENY">               <KeyValuePair key="true" value="DEBUG"/>             </DynamicThresholdFilter>             <PatternLayout>                ....             </PatternLayout>             <Policies>                 <SizeBasedTriggeringPolicy size="5000KB" />             </Policies>             <DefaultRolloverStrategy max="20" />              </RollingFile> 

My expectation is that ONLY the loggers referring to this appender will be logging at debug level
