In an earlier post I wrote about monitoring your cache hits in a Grails Application using a programmatic approach, this time I will show you how to use jconsole and have it done for you automatically.
All you need to do is start your Grails Application: grails run-app. Then start jconsole and choose your running Grails' process. Go over to the MBeans tab and navigate to the area of your application server where you can see the cache.
What I really love about this is that you can perform actions in your application and watch the cache hits over time.
