如何以编程方式获取jmap直方图？ [英] How to get jmap histogram programmatically?

问题描述

我想从受监控的应用程序内部以编程方式获得 jmap -histo 的输出。我看到通过HotSpot诊断bean可以触发二进制堆转储，但我看不到如何获取直方图数据。有可能吗？

I would like to get the equivalent of the ouput of jmap -histo programmatically, from inside the monitored application. I see triggering a binary heap dump is possible through the HotSpot diagnostic bean, but I can't see how to get the histogram data. Is it possible ?

推荐答案

这可能不是最好的示例/代码，但看看此

It may be not the best example/code, but have a look at this

（我认为它只适用于Hotspot JVM）

(I think it's only working on Hotspot JVMs)
