Sensu Check JMX Jolokia

This is the updated and improved version of inokappa's sensu-plugin-check-jmx-jolokia plugin. This version has been updated to use the new Timeout function introduced in later versions of Sensu. It also allows checking MBeans which return Strings. *This plugin requires Jolokia to be running on the host machine, exposing the JMX beans that you want to monitor.

Install

Put to your sensu plugins directory.

sudo cp check-jmx-jolokia.rb /etc/sensu/plugins/
sudo chmod 755 /etc/sensu/plugins/check-jmx-jolokia.rb
