Integrate JavaMelody Monitoring into grails application.
The plugin will copy a GrailsMelodyConfig.groovy to your grails-app/conf directory. Basically you don't have to change this file to run grails melody plugin. Link to Release notes of JavaMelody (and of JavaMelody Grails Plugin)There are known issues, see here.
grails install-plugin grails-melody
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 overwrites original grails 'dataSource' bean in spring context with a JavaMelody datasource proxy.
- grails-melody plugin uses groovy meta programming to intercept grails services method calls.
to disable the JavaMelody monitoring.JavaMelody uses URIs to resolve HTTP requests. This means that
javamelody.disabled = true
will resolve as different requests. While that's desirable in some cases, often you want the statistics to be gathered for the show action, irrespective of parameters. In that case, add the following configuration to GrailsMelodyConfig.groovy and the above URIs will show up as /book/show/$.
/book/show/1 and /book/show/23
Similar issue comes up for SQL monitoring - use a similar Regex to filter it.
javamelody.'http-transform-pattern' = '\\d+' //filter out numbers from URI
javamelody.'sql-transform-pattern' = '\\d+'
