JMX Bean for few types of Requests

I want to show performance statistics for particular request type. When Controller class gets the HTTP Request from browser, it then marshals request xml in to a request object. From request object I can get request type.
Is it possible to inject JMX MBeans for particular request type and broadcast it to JConsole?

  • Is it possible to inject JMX MBeans for particular request type and broadcast it to JConsole?

    Jconsole does polling of statistics and you can't "broadcast" a request type that you define since that class won't be in the Jconsole jar.

    What you can do is keep a count of the request types in a map and then return a String[] of type -> count string output if you like. Something like:

    public String[] getResultTypeCount() {
     List<String> list = new ArrayList<String>();
     for (Map.Entry<String, Integer> entry : typeMap.entrySet()) {
         list.add(entry.getKey() + " => " + entry.getValue());
     }
     return list.toArray(new String[list.size()]);
}

    You might want to look into JMX notifications.
