jmx monitoring

Apache Geronimo is built on a common reverse control (IoC) kernel that supports the JMX framework, which oversees a collection of managed components called Geronimo Beans (GBeans). Geronimo is created with JMX as the underlying kernel structure, and is somewhat similar to the JMX Managed Beans (Mbeans). The Apache Geronimo structure changes slightly over time bec

System. Before Zabbix 1.8, you can only use Zapcat to monitor jmx and need to modify the source code to support it, which is cumbersome. Another approach is to use jmx-cmd-client, which is to get jmx information from the command line, and to wrap a program on top of it to get JMX data. starting with Zabbix2.0, the bui
