If I had to guess, one of two scenarios is possibly going on.
Scenario 1: The methods you are trying to instrument are not getting invoked; code must execute to produce metrics.
Scenario 2: You are instrumenting too high up in the inheritance tree. For intance, let's say c[font=Courier New]om.xx.yyy.zzz.Class1[font] is an interface or abstract class (I assume abstract class, since you're using [font=Courier New]IdentifyInheritedAs[font] and [font=Courier New]IdentifyClassAs[font] both). By default, all direct descendents (subclasses or implementations) from this class will be modified by ProbeBuilder and added to the specified tracer group. For example, let's assume a class hierarchy in which [font=Courier New]Class2[font] extends [font=Courier New]Class1[font], and [font=Courier New]Class3[font] extends [font=Courier New]Class2[font], like so:
[font=Courier New]com.xx.yyy.zzz.Class1[font]
[font=Courier New]└ com.xx.yyy.zzz.Class2[font]
[font=Courier New]└ com.xx.yyy.zzz.Class3[font]
When you instrument by inheritance for [font=Courier New]Class1[font], [font=Courier New]Class2[font] is instrumented because it explicitly extends [font=Courier New]Class1[font]. However, Introscope does not by default instrument [font=Courier New]Class3[font] because [font=Courier New]Class3[font] does not explicitly extend [font=Courier New]Class1[font]. So, if the methods that you are targeting are defined in [font=Courier New]Class3[font], your current PBD might not be getting applied. To instrument [font=Courier New]Class3[font] you must either explicitly identify [font=Courier New]Class3[font] (either directly or using inheritance starting at [font=Courier New]Class2[font]) or by enabling AutoProbe hierarchy support.
