Description:
When using JMX to monitor service container environment data, you need to use each parameter query name, the following lists the monitoring code under each container and the configuration of the query parameter name:
Java Implementation Example:
Import Javax.management.MBeanServer;
try{
//Like Tomcat get ThreadPool information
String squeryname = "catalina:type=threadpool,*";
Mbeanserver mbs = Managementfactory.getplatformmbeanse
JMX Configuration
The remote machine program needs to add JVM parameters
-dcom.sun.management.jmxremote=true
-dcom.sun.management.jmxremote.port=9090
- Dcom.sun.management.jmxremote.ssl=false
-dcom.sun.management.jmxremote.authenticate=false
Note: Another need to check the hostname–i, see whether the resolution is local IP, if 127.0.0.1 or IP is one of multiple IP, then other IP is invalid, will not connect.
You can also manually specify hostname o

The Java Management API (JMX) is required to manage WebLogic servers. With this API, you can search the application server for admin beans (Mbeans) and through them you can query both configuration information and runtime monitoring information. In addition, this API can also be used to change the configuration of the server. In fact, this API has been used on consoles and other management tools to complete their work and provide reporting data.

Recently participated in the development of SMS Gateway, the development technology adopted SPRING+HIBERNATE+MULE+JMS; The information sent from the business layer to the mobile user is first sent to a team joins (JMS:QUEUE_MT) on the JMS server, and the SMS Gateway monitors the queue (JMS: QUEUE_MT), if a new message is found in the queue, it is ready to be sent, which allows for a loose coupling of the architecture.
However, due to the mobile side of the sliding window size is only 16, if a fe
