工作须要，得监控weblogic的指标，例如:连接池、线程数、JMS明细、EJB明细,等指标!在网上了解了一下JMX原理，也做了一个JMX的Hello例子，但是要监控weblogic不知道如何动手，得到了与weblogic的Mbeanserverconnection,但是不知道怎么得到我要的监控指标，是还要注册相应的Mbean？该Mbean要怎么写呀？又怎么从Mbean上得到相应的监控数据,自己做的JMX例子好像太浅，希望哪位JMX老手指点一下，能否提供点JMX资料!我得到Mbeanserverconnection的代码如下:
private static MBeanServerConnection lookupMBeanServer9(String ip, String port, String name, String pass)
{
String protocol;
String s5;
protocol = "t3";
s5 = "/jndi/weblogic.management.mbeanservers.runtime";
MBeanServerConnection mbeanserverconnection;
try
{
//JarLoader jarloader = new JarLoader((new StringBuilder()).append(".").append(File.separator).append("working").append(File.separator).append("classes").append(File.separator).append("weblogicclient9.jar").toString());
//Thread.currentThread().setContextClassLoader(jarloader);
JMXServiceURL jmxserviceurl = new JMXServiceURL(protocol,ip, Integer.parseInt(port), s5);
Hashtable hashtable = new Hashtable();
hashtable.put("java.naming.security.principal", name);
hashtable.put("java.naming.security.credentials", pass);
hashtable.put("jmx.remote.protocol.provider.pkgs", "weblogic.management.remote");
JMXConnector jmxconnector = JMXConnectorFactory.connect(jmxserviceurl, hashtable);
mbeanserverconnection = jmxconnector.getMBeanServerConnection();
return mbeanserverconnection;
}catch(Exception ex){
ex.printStackTrace();
}
return null;
}
[align=left]需要了解weblogic的MBean结构，你可以去bea网站查看相关资料，了解其结构后就很容易得到这些指标了，以下给出简单的示例代码：
