Tags: jmx server system monitoring cpu virtual machineNext, we provide another implementation method:First look at a class diagram:JDK implements nine built-in mbeans that can monitor all the information of virtual machines: ManagementFactoryThe factory class can get the corresponding MBean instance through ObjectName, and naturally the desired data can be obtained.2 The code is as follows:Package pyc. jvm.

Third, test whether JMX successfully configured Start Tomcat, enter in Windows command window: Netstat-aon | Findstr "8999" If this port is already in use, it proves that the JMX configuration was successful Four, turn on JMX monitoring Run%java_home%\lib\jconsole.jar Enter Tomcat machine IP, port input 8999 If you

After getting familiar with JMX, the problem is that mbean is located on a remote server and RMI is required for access. JMX also provides the RMI method. Based on the JMX example helloagent.

();}}This code first creates an MBean Server instance and an Html adapter instance. The MBean Server is created using a factory class. When the MBean Server is created, the input string is used as the domain name of the MBean Server. The domain name is the identifier of the MBean Server.Next, instantiate HelloWorld MBean and register it in MBean Server. An ObjectName instance is used for registration. The ObjectName class provides a naming system for MBean in
