InterceptFramework Operation Principle

Illustration

• InterceptSupport: a singleton as the uniform access point for Profile/Client hook capturing
• InterceptContext: an interface that captures the context. All captured parameters are packaged by Context
• InterceptEventListener: a event hooking listener. All listeners should be inherited and registered for listening
• AppProfilingListener: a server profile listener that listens to all server profile events
• AppFrkHookFactoryListener: a client profile listening agent
• DataObserver: exposes JMX interface data

Key Technologies

• JavaAsssist
• HOOK(hooking framework)
• webAppClassLoader

Key Class and Functionality

• The profile data and the client- monitoring metrics are captured and monitored via the InterceptSupport and hookProxy mechanism.
• The monitoring data is stored in DataStore and provides the JMX interface.
