When you identify a method you want to instrument, right-click the method to open the Add Rule editor. Splunk AppDynamics automatically populates the class and method configuration based upon your search criteria from the Class/Method browser. You can right-click a class to instrument it, but you must add the method before you can save the POJO or POCO. Complete the custom match rule for the POJO or POCO as normal.
