如何以编程方式转储JMX数据?

java.lang.management.ManagementFactory 允许您访问jmx数据。

I.G.

List<MemoryPoolMXBean> memPoolBeans = ManagementFactory.getMemoryPoolMXBeans();
for (MemoryPoolMXBean mpb : memPoolBeans) {
    System.out.println("Memory Pool: " + mpb.getName());
}

有些查询是在这样的查询:[ java] +管理工厂

对于连接到远程虚拟机的完整实现:

Map<String,String[]> env = new HashMap<String, String[]>();
env.put( JMXConnector.CREDENTIALS, new String[]{"user","pass"} );
JMXServiceURL address = new JMXServiceURL("service:rmi:///jndi/rmi://host:port/jmxrmi");
JMXConnector connector = JMXConnectorFactory.connect(address,env);
MBeanServerConnection mbs = connector.getMBeanServerConnection();

//get all mbeans
Set<ObjectInstance> beans = mbs.queryMBeans(null,null);

for( ObjectInstance instance : beans )
{
    MBeanInfo info = mbs.getMBeanInfo( instance.getObjectName() );
}

从信息中,您可以根据需要查询对象名称和属性。

我用过这个 command line JMX client 作为我想做同样事情的起点。
