MXBeans有什么问题？实施并不那么难.
我用过类似的东西：
List gcList = ManagementFactory.getGarbageCollectorMXBeans();
for(GarbageCollectorMXBean tmpGC : gcList){
System.out.println("\nName: " + tmpGC.getName());
System.out.println("Collection count: " + tmpGC.getCollectionCount());
System.out.println("Collection time: " + tmpGC.getCollectionTime());
System.out.println("Memory Pools: ");
String[] memoryPoolNames = tmpGC.getMemoryPoolNames();
for(String mpnTmp : memoryPoolNames){
System.out.println("\t" + mpnTmp);
}
}
System.out.println( "Memory Pools Info" );
List memoryList = ManagementFactory.getMemoryPoolMXBeans();
for(MemoryPoolMXBean tmpMem : memoryList){
System.out.println("\nName: " + tmpMem.getName());
System.out.println("Usage: " + tmpMem.getUsage());
System.out.println("Collection Usage: " + tmpMem.getCollectionUsage());
System.out.println("Peak Usage: " + tmpMem.getPeakUsage());
System.out.println("Type: " + tmpMem.getType());
System.out.println("Memory Manager Names: ") ;
String[] memManagerNames = tmpMem.getMemoryManagerNames();
for(String mmnTmp : memManagerNames){
System.out.println("\t" + mmnTmp);
}
System.out.println("\n");
}
MemoryUsage mu =ManagementFactory.getMemoryMXBean().getHeapMemoryUsage();
MemoryUsage muNH =ManagementFactory.getMemoryMXBean().getNonHeapMemoryUsage();
System.out.println(
"Init :"+mu.getInit()+
"\nMax :"+mu.getMax()+
"\nUsed :"+mu.getUsed()+
"\nCommited :"+mu.getCommitted()+
"\nInit NH :"+muNH.getInit()+
"\nMax NH :"+muNH.getMax()+
"\nUsed NH:"+muNH.getUsed()+
"\nCommited NH:"+muNH.getCommitted());
