Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bytecode instrumentation-based performance monitoring tools face challenges such as increased resource overhead, potential application crashes due to memory consumption, and network bottlenecks when monitoring globally-distributed applications over non-secured, low-bandwidth connections.
Innovation Solution
Decoupling measurement acquisition and instrumentation processes by using collector nodes to instrument and buffer data, allowing for parallel instrumentation engines and secure, compressed data transfer over non-secured networks, thereby reducing network bandwidth and runtime burdens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If bytecode instrumentation is performed to monitor application performance at fine-grained level, then measurement precision is improved, but device complexity and resource overhead increase
Solution Approach 1:
The patent introduces collector nodes as intermediary components between application nodes and the central monitoring node. These collector nodes receive instrumented bytecode and event data from application nodes, buffer them temporarily, and then transfer to the central monitoring node. This intermediary layer decouples the instrumentation process from the data collection process, reducing the complexity burden on individual application nodes while maintaining fine-grained measurement capability.
Solution Approach 2:
The patent segments the monitoring system into multiple collector nodes distributed across different locations. Instead of having a single centralized instrumentation engine, the workload is divided among multiple collectors that can process instrumentation and data collection in parallel. This segmentation reduces the resource overhead on any single node while maintaining comprehensive monitoring coverage.
2Measurement precision
If large quantity of bytecode instrumentations are placed into application bytecode, then measurement precision is improved, but reliability deteriorates due to potential application crashes
Solution Approach 1:
By introducing collector nodes as intermediaries, the patent separates the instrumentation code from the application logic execution. The collector nodes handle the complex instrumentation processing and data aggregation, while application nodes only execute the instrumented bytecode without managing the instrumentation overhead directly. This reduces the risk of application crashes caused by memory consumption or resource exhaustion from instrumentation.
Solution Approach 2:
The patent performs instrumentation actions in advance by transferring instrumented bytecode to application nodes before they are executed. The collector nodes pre-process and buffer the instrumented bytecode and event data, so that when application nodes execute the bytecode, the instrumentation overhead is already prepared and managed by the collector infrastructure rather than being imposed on the application runtime.
3Adaptability or versatility
If original bytecode and instrumented bytecode are transferred over network connections, then adaptability is improved for distributed applications, but network bandwidth consumption increases
Solution Approach 1:
The patent performs preliminary compression and encryption of bytecode and event data at the collector nodes before network transmission. By preparing the data in a compact and secured format beforehand, the system reduces the amount of data that needs to be transmitted over network connections, thereby lowering bandwidth consumption while maintaining support for distributed applications.
Solution Approach 2:
The patent uses copying mechanisms where collector nodes receive and buffer copies of event data and bytecode, then transmit only the necessary information to the central monitoring node. This copying approach allows for local processing and filtering at collector nodes, reducing the volume of data that needs to traverse the network while maintaining the ability to monitor distributed applications.
4Ease of operation
If centralized instrumentation engine is used, then ease of operation is improved through centralized management, but productivity deteriorates due to single point of bottleneck
Solution Approach 1:
The patent segments the centralized instrumentation function into multiple distributed collector nodes. Each collector node independently processes instrumentation requests and buffers event data from application nodes, eliminating the single point of bottleneck. The segmentation maintains centralized management capability through a central monitoring node that coordinates instrumentation rules, while distributing the actual instrumentation processing workload across multiple parallel collectors to improve overall productivity.

AI summary
Methods and systems for out-of-application bytecode instrumentation and performance monitoring of applications, such as globally-distributed applications, decouple (1) acquiring measurements through sensor execution at applications; (2) instrumenting application bytecode with sensor bytecode and buffering and sending measurements at collector nodes; and (3) controlling instrumentation and correlating measurements at a central monitoring node. Collector nodes and applications may employ secured, high bandwidth network connections (e.g., a typical LAN connection). Collector nodes and the central monitoring node may employ non-secured, lower-bandwidth network connections (e.g., a typical WAN connection) and may use encryption and/or compression without burdening the monitored application. Multiple parallel instrumentation engines in collector nodes eliminate the possible instrumentation bottleneck presented by one centralized instrumentation engine in a single server. Moreover, decentralized buffering of monitoring event data allows management of peak measurement loads on the monitoring node.
