You can use the ObjectName instance as a parameter to most Mbeanserver methods to retrieve properties and invoke actions on the MBean. For example, you can invoke an Mbean operation by invoking the Invoke method on the server by obtaining a reference to the Mbean server. When a re

Recently in doing a monitoring agent component development work, the main is to collect a variety of system metrics information, and then reported to the monitoring system, in order to monitor and alarm. The goal is to achieve au
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

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:
