java - profiling the jvm where most garbage is generated and what type it has, escape analysis optimization

Question

I know that my program invokes the gc in regular intelvals, but I would like to analyse only the generated garbage. I want to know which classes are most frequently abandoned, and much more important, where are those instances created. Generally I want to optimize for escape analysis to reduce the garbage collection to a minimum.

Edit: I am not interested in live objects.

JProfiler为您提供有关垃圾收集对象的统计信息。分配树和热点甚至会显示它们的创建位置。

在“记录对象”视图中，将“活动模式”更改为“垃圾收集对象”：
