CaptureFramework Operation Principle

Illustration

• Capture point: supports Tomcat, MSCP, Springboot and Jetty tracking
• UAVServer singleton: a uniform capture access point
• StandardMonitor: an implementation class that captures the monitoring data. Responsible for capturing data and generating the capturing results
• MonitorElemCapHandler: a common interface for different capturing logic and capturing points, which makes different tracking logic possible
• StandardMonitorRepository: stores the structure of the captured monitoring data
• DataObserver: exposes JMX/Http interface data

Key Technologies

• JavaAssist
• Monitor capturing system
• precap/docap

Key Class and Functionality

• The runtime monitoring starts and initializes the StandardMonitor object with the DefaultMonitorSupporter class and then builds the monitoring objects into the DataStore object via CaptureFramwork
• DataStore provides the JMX/HTTP service for the upcoming MA capturing
• The handler class under the MonitorHandler package calculates and summarizes the metrics of the monitor.
