   Check out java.lang.management.MemoryPoolMXBean and related classes.

   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;
   
   }
