logging - How to filter out Jetty DEBUG messages in slf4j/log4j2? -


i added embedded jetty/jersey server application, uses log4j2 logging provider slf4j bindings. logging libraries in classpath , jetty uses them, described here:

https://www.eclipse.org/jetty/documentation/9.4.x/configuring-logging.html

this thing, except debug level in jetty noisy, mentioned there.

i have 3 appenders (one console , 2 file) @ different levels, file name 1 of them configured programmatically, besides that, configuration specified in log4j2.properties file. setup little complicated, need.

is there simple way convert jetty debug messages trace before message strings processed , / or filter out debug messages altogether based on package name?

i don't expect it's easy or or possible convert logging levels, doesn't hurt ask.

and far filtering concerned, in other words, i'd specify different levels depending on package, info org.eclipse.jetty , subpackages trace default, or trace package , subpackages info default. ideally, should done in 1 place, doesn't have be.

i'm still little confused about loggers , appenders, got work partly trial , error. example, rootlogger.level doesn't seem affect anything, i'm guessing can't specify filters through rootlogger. references found suggest creating logger name matching specific class, i'm not sure how work problem -- work package/subpackage level filtering and, if so, need create multiple loggers write same appenders?

how give org.eclipse.jetty logger , set error level , additivity=false, , appender console or log, won't log root logger bother you.

<appenders>             <console name="console" target="system_out">         <patternlayout pattern="%-5p:[%c.class(%c{1}.java:%l)] %m%n"/>                  </console>                 </appenders>  <logger name="org.eclipse.jetty" level="error" additivity="false">                 <appenderref ref="console"/> </logger>
