Changing Logback specific logger level to INFO. Plesa remember to add the jmx configuration to your logback.xml

<configuration scan="true" scanPeriod="5 seconds" >
  <jmxConfigurator />

runnig the script

In order to be able to run the script you need groovy. You can install it by:

• official way: http://groovy.codehaus.org/Installing+Groovy
• oniliner way: http://gvmtool.net/ curl -s get.gvmtool.net | bash
• or run it via maven (description later ...)

Once you installed groovy you can run the script directly from github:

groovy https://raw.github.com/gist/5110992/getMbeanAttribute.groovy
