Last updated by burtbeckwith 1 year ago
JMX Plugin
This plugin adds JMX MBeanServer support through Spring and configures a number MBeans.
Plugin features:
- Configures MBeanServer in Grails Application
- Registers services which are singletons and annotated with: static expose = ['jmx'] with JMX
- Provides default object naming {appname}:service=${serviceName},type=service
- Allows for object name override: static expose = ['jmx:service=Country,type=special']
- Allows for exclusion map: static jmxexpose = ['excludeMethods':'isTransactional,setTransactional,getTransactional,getJmxexpose,setJmxexpose,getExpose,setExpose']
- Checks to see if Hibernate is a plugin and if so it exposes the Hibernate Statistics
- Exposes Log4j for runtime logging level configuration
- Exposes the Grails DataSource
- Allows for any spring bean to be exposed through Config.groovy
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 administer.
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 { static transactional = true
static expose = ['jmx']
…
}
This will expose the service leverage a convention for the service name. Alternatively you can be very explicit on the object through the following example:
class CountryService { static 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
