sun.misc.Perf文档或替代方法 [英] sun.misc.Perf documentation or alternative

问题描述

我知道sun.*软件包不是官方Java API的一部分.但是，我需要使用一些与Perf提供的功能类似的功能:特别是基本JVM度量标准(堆，线程，PermGen等)，针对GC的JvmStat计数器等.是否有人知道Perf和附带了很好的文档.

I understand that the sun.* packages are not part of the official Java API. However, I need to use some functionality similar to what Perf offers: specifically Basic JVM Metrics (Heap, Threads, PermGen, etc), JvmStat counters to GC, etc. Does anybody know a wrapper library around Perf and PerfInstrumentation which comes with a good documentation.

我需要将其用作API，例如VisualVM的Tracer插件还不够好.有人对此发表评论吗?

I need to use it as an API so e.g. the VisualVM's Tracer plugin is not good enough. Anybody has a comment on that?

推荐答案

jvm中有围绕JVM性能计数器的包装器-attach 库，尽管文档并没有任何改善(即没有文档).

There are wrapper around JVM perfcounters in jvm-attach library, though documentation is not any better (i.e. it is absent).

jvm-attach 库本身是JVM诊断接口的包装，包括堆转储，JMX等

jvm-attach library itself is a wrapper around JVM diagnostic interfaces including heap dumps, JMX etc
