MBean (Managed Bean)
is typically a Java class that provides an interface that enables the class to have functionality that can be managed (successfully registered on the server). It usually represents a program that we want to actually manage, or a device, and so on, which we encapsulate with the specification of Mbean.

JK is the most commonly used Apache and Tomcat connection, the latest version is JK-1.2.37 released, JK is through the AJP protocol with the Tomcat server communication, tomcat default AJP Connector port is 8 009. JK itself provides a monitoring and management of the page jkstatus, through Jkstatus can monitor the current working status of JK and the connection to Tomcat settings, Access can be http://IP/jkstatus.

The previous tools are based on a prior model and have been used to detect known patterns and rules. Automatic Processing of complex, heterogeneous, and large-scale data often fails, therefore, we need to visualize the data analysis process to better explore patterns and find problems.
