Plugin Url : https://grails.org/plugin/grails-melody

Installation step provided does not work with grails 2.3.4 or above. 

This method to install plugin has been deprecated in new version of grails. 

grails install-plugin grails-melody


To Add Java Melody to Grails App add following dependency in you BuildConfig.groovy in Plugin 
Section. 

plugins {
      compile ":grails-melody:1.56.0"
     // 1.56.0 add latest version as per your requirement
}

After this save your BuildConfig.groovy file and compile you grails Application : 
cd in you grails App directory  and run  :$  grails compile

Checkout console messages grails will install java melody jar and add GrailsMelodyConfig.groovy 
in your grails-app/config folder. (in same directory as your BuildConfig,groovy). 

You can use this file to configure java melody properties : 
Please refer for mode details but remember to properties in grails dsl style not xml : http://code.google.com/p/javamelody/wiki/UserGuide

Example : 
javamelody.'displayed-counters' = 'http,sql,error,log,spring,jsp'
javamelody.'sql-transform-pattern' = '\\d+'
javamelody.'http-transform-pattern' = '\\d+'  //filter out numbers from URI
javamelody.'url-exclude-pattern' = '/static/.*' 

Last and final step to configure endpoint of JavaMelody 

http://localhost:8080/<YourContext>/monitoring

Edit your Config.groovy file and add following line in your file. 
Always ensure to secure monitoring/** url path under some password 
protected spring role. ROLE_ADMIN  in our example. 

grails.plugins.springsecurity.interceptUrlMap = [
	
	'/monitoring/**':                 ['ROLE_ADMIN'],
	'/admin/**':			  ['ROLE_ADMIN']]
]

Thats it , run your grails app and access http://localhost:8080/<YourContext>/monitoring,
provide the password and you should see java melody UI.
