通过Java 5使用jmx以编程方式获取堆信息 [英] Programatically get heap info using jmx with java 5

问题描述

我知道使用jconsole附加到Java进程来获取内存信息.具体来说，我是通过编程方式获取有关各种内存池的信息，因此可以将其绑定到监视应用程序.

I am aware of using jconsole to attach to a java process to get memory information. Specifically I'm after getting information on the various memory pools programatically so I can tie it to a monitoring application.

谢谢！

推荐答案

感谢mattk-我基本上是这样做的:-)

Thanks mattk - I wound up doing basically this :-)

List memBeans = ManagementFactory.getMemoryPoolMXBeans();           
for (Iterator i = memBeans.iterator(); i.hasNext(); ) {

    MemoryPoolMXBean mpool = (MemoryPoolMXBean)i.next();
    MemoryUsage usage = mpool.getUsage();

    String name = mpool.getName();      
    float init = usage.getInit()/1000;
    float used = usage.getUsed()/1000;
    float committed = usage.getCommitted()/1000;
    float max = usage.getMax()/1000;
    float pctUsed = (used / max)*100;
    float pctCommitted = (committed / max)*100;

}
