使用jmx和java 5以编程方式获取堆信息

Question

我知道使用jconsole附加到java进程以获取内存信息.具体来说,我是以编程方式获取有关各种内存池的信息,因此我可以将其与监控应用程序联系起来.

谢谢!

谢谢 mattk - 我基本上就是这样做的:-)

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;

}
