Question

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.

Thanks!

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;  }
