JMX Plugin

This plugin adds JMX MBeanServer support through spring and configures a number MBeans.

NOTE: This is still is an early release.

Plugin features:

• Configures MBeanServer in Grails Application
• Exposes Log4j for runtime logging level configuration
• Exposes the Grails DataSource
• Exposes Any Service configured for jmx
• Allows other Spring beans to be configured for jmx

Setup

grails install-plugin jmx

There is nothing to do after the install if you have no services to expose. Just run the application and use jconsole to administrate.

However to be able to connect to the exposed services (which also includes the ones made available by the plugin by default) you have to set the system property com.sun.management.jmxremote before running your app.

Exposing Services

By default, the plugin only supports exposing Services. This is accomplished by add 'jmx' to the static expose property as outlined below:

class StateService {
    boolean transactional = true
    static expose = ['jmx']

class CountryService {
    boolean transactional = true
    static expose = ['jmx:service=Country,type=special']

Exposing Spring Beans

The plugin also supports exposing other Spring Beans - e.g. registered via resources.groovy . This is accomplished by adding 'jmx' to the static expose property as outlined above and using the following code in Config.groovy -

grails {
	jmx {
		exportBeans = ['myBean']
	}
}

Future plans

• Check for proper ObjectName
• Expose Jetty Services
