Configure
Jetty comes with pre built support of Jolokia, but module is disabled by default.
All is needed is just to enable jolokia and restart Jetty.
cd $JETTY_HOME
bin/jetty.sh stop
java -jar start.jar --add-to-start=jolokia
bin/jetty.sh start
After enabling Jetty-Jolokia copy or symlink checks_available/check_jetty.py to checks_enabled/check_jetty.py,
Change IP:PORT of Jetty server at section [Jetty] of conf/webservers.ini to match IP:PORT of your server.
