I would like to be able to retreive the object count for instrumented classes. I am not sure if it is possible to automatically store this type of data in the Agent (or it it is a desirable feature of the BTrace Agent).

The reason for wanting this feature is because I need some sort of "mini" jmap -histo:live feature for the instrumented application. If maintaining a list of the instrumented classes and its current object count is both easy to implement and easy on the resources required this could be a nice addition to BTrace.

A BTrace script could retreive the data using the standard StringFormat approach as both Aggregation and Profiler has today, something like

Profiler.printObjectCount(String format)

I will be happy to assist in developing this feature, but I will need some pointers as to where in the code this might be added.
