logging - Druid.io (imply): log level settings -

during druid.io work found out log files located in /druid_dir/var/sv/ takes gigabytes of space.

to fix problem want set log level error

i put in common.runtime.properties

druid.emitter.logging.loglevel=error 

and in log4j2.xml:

configuration status="error" 

but .log files still grow huge sizes (and includes info messages).

what else should added config?

need update root logger level in log4j2.xml:

<root level="error">
