Hyper Dynamic JMX Framework for Runtime Metric Exposure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Java Management Extension (JMX) technologies are limited in dynamically exposing metrics and managing application performance, as they require static MBeans and cannot add or remove attributes or operations at runtime, making it difficult to maintain high service performance and user experience in complex web service infrastructures.
Innovation Solution
The Hyper Dynamic JMX framework uses a dynamic MBean proxy with reflection chaining techniques to create a highly dynamic infrastructure for exposing JMX attributes, allowing for dynamic creation and modification of attributes and operations without restarting the JVM, enabling on-demand exposure of metrics and analytics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If static MBeans are used in traditional JMX, then system stability is maintained, but the ability to dynamically expose metrics at runtime is limited
Solution Approach 1:
The patent implements dynamic MBeans that can add, remove, and modify attributes and operations at runtime without requiring JVM restart. The MBean structure transitions from static to dynamic, allowing the management interface to adapt to changing monitoring requirements while the application is running.
Solution Approach 2:
The patent separates the MBean structure into configurable components (attributes, operations, relationships) that can be independently managed and modified. This segmentation allows specific metrics to be exposed or hidden without affecting the entire MBean structure, enabling fine-grained dynamic control.
2Adaptability or versatility
If code changes are made to expose new metrics, then metric exposure capability is improved, but development time and total cost of ownership increase
Solution Approach 1:
The system enables runtime configuration of MBean attributes and operations without requiring developer intervention or code changes. Administrators can dynamically expose new metrics by configuring the dynamic MBean, which automatically generates the necessary management interface elements.
Solution Approach 2:
The patent allows changing the parameters of the MBean management interface at runtime, including adding new attributes, modifying existing ones, and creating new operations. These parameter changes take effect immediately without requiring recompilation or restart of the Java application.
3Adaptability or versatility
If JVM restart is performed to add new MBeans, then complete metric exposure is achieved, but service availability and performance are degraded
Solution Approach 1:
The dynamic MBean implementation allows the MBean structure to be modified at runtime without stopping the Java Virtual Machine. New attributes, operations, and relationships can be added or removed while the application continues to run, maintaining service availability.
Solution Approach 2:
The system performs preliminary setup of the dynamic MBean framework during application initialization, establishing the infrastructure for runtime modifications. This preliminary action enables subsequent dynamic changes to be made without requiring JVM restart, as the framework is already in place to handle dynamic configuration.
4Productivity
If traditional JMX is used without dynamic capabilities, then system simplicity is maintained, but troubleshooting and performance management capabilities are limited
Solution Approach 1:
The patent introduces a dynamic MBean layer that acts as an intermediary between the existing JMX infrastructure and the application being monitored. This intermediary provides dynamic configuration capabilities while leveraging the established JMX mechanisms for metric collection and exposure, minimizing the need for fundamental architectural changes.

AI summary
In one aspect, a system for exposing application metrics on the fly is disclosed. The system includes a processor; a memory; and one or more modules stored in the memory and executable by a processor to perform various operations. The operations include initialize a Java managed object for Java Management Extension (JMX); attach the initialized Java managed object to a repository for Java managed objects accessible by applications; create a fixed reference to an attributes field in the attached Java managed object; provide the created fixed reference to the repository after initialization of the Java managed object; save the fixed reference; describe an attribute to be created; and create a new attribute in the Java managed object.
