This plugin integrates JavaMelody system monitoring tool into grails application. When a grails application is installed with grails-melody plugin, you will be able to monitor the application at http://localhost:8080/<YourContext>/monitoring.

The goal of JavaMelody is to monitor Java or Java EE applications servers in QA and production environments. It is not a tool to simulate requests from users, it is a tool to measure and calculate statistics on real operation of an application depending on the usage of the application by users.

A few things you might want to know:

  • grails-melody plugin overwrite original grails 'dataSource' bean in spring context with a JavaMelody datasource proxy.
  • grails-melody plugin use groovy meta programming to intercept grails services method calls.
The plugin copies a GrailsMelodyConfig.groovy file into your project's grails-app/conf directory. All JavaMelody parameters described at http://code.google.com/p/javamelody/wiki/UserGuide#5._Optional_parameters can be configured in this file with 'javamelody.' prefix. For example, use 
javamelody.disabled = true
to disable the JavaMelody monitoring.
