Amazon CodeGuru Profiler now profiles your application’s memory, giving you a consolidated view of the heap. The heap summary shows all objects allocated on the heap during a given time frame. For each object (e.g. String, int, char, custom types, etc.) you can see a summed-up size and number of objects. These metrics are also presented in a time series so you can see how the object size or count changes over time.
