If you want to adjust on a per topology basis create a logback config and package in uber jar
The config should be an included logback config file rather than stand alone, so root tag is <included> After that all storm cluster.xml files should be updated to include <include optional="true" resource="logback_include.xml"/> From: Lin Zhao [mailto:l...@groupon.com] Sent: 21 April 2014 18:10 To: user@storm.incubator.apache.org Subject: Re: Logging levels You should probably add a new logger and appender for your topology such that it doesn't include storm's infrastructure logging. e. g. <appender name="A1" class="ch.qos.logback.core.FileAppender"> <file>myApp.log</file> <encoder> <pattern>%d{yyyy-MM-dd HH:mm:ss} %c{1} [%p] %m%n</pattern> </encoder> </appender> <logger name="com.my.awesome.topology" level="INFO"> <appender-ref ref="A1"/> </logger> On Mon, Apr 21, 2014 at 9:42 AM, Software Dev <static.void....@gmail.com<mailto:static.void....@gmail.com>> wrote: Is there any way to adjust this per topology or project as opposed to system wide?
