Dynamic Profiler Scope Adjustment for Memory Overhead Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional code instrumentation systems impose unnecessary memory overhead and increased execution time due to static instrumentation scope profiles, which do not adapt dynamically, leading to inefficient resource usage and potential overlooking of application components.
Innovation Solution
A system and method for dynamically adjusting the instrumentation scope by using a profiler agent and a scope optimization engine that updates the instrumentation scope profile based on performance data, expanding or narrowing the scope of code instrumentation to optimize resource usage without compromising tracing capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the scope of code instrumentation is expanded to monitor more application components, then the tracing capacity and diagnostic capability are improved, but the memory overhead and execution time increase
Solution Approach 1:
The patent implements dynamic adjustment of instrumentation scope by monitoring system performance metrics in real-time and automatically expanding or contracting the instrumentation coverage. The system transitions from static to dynamic scope management, adapting the instrumentation level based on current system state, performance thresholds, and diagnostic needs without requiring system restart or manual reconfiguration.
Solution Approach 2:
The system changes the parameter of instrumentation scope dynamically by adjusting the set of monitored application components based on performance data and diagnostic requirements. This allows the system to modify the extent of code instrumentation coverage, injecting or removing instrumentation code at runtime to optimize between tracing capacity and resource consumption.
2Measurement precision
If the scope of code instrumentation is expanded to monitor more application components, then the tracing capacity is improved, but the execution time increases
Solution Approach 1:
The system dynamically adjusts instrumentation scope to balance tracing capacity with execution time performance. By monitoring performance metrics and automatically adapting the instrumentation coverage, the system ensures comprehensive tracing only when necessary, reducing unnecessary overhead and maintaining optimal execution speed while preserving diagnostic capability.
Solution Approach 2:
The system modifies the instrumentation scope parameter dynamically based on performance thresholds and diagnostic needs, allowing flexible adjustment between tracing depth and execution speed without requiring system restart or manual reconfiguration.
3Device complexity
If a static instrumentation scope profile is used, then the system simplicity is maintained, but the adaptability to changing system conditions deteriorates
Solution Approach 1:
The system implements self-service through automatic performance monitoring and self-adjustment of instrumentation scope. The system autonomously evaluates performance metrics, determines optimal instrumentation levels, and modifies its own behavior without external intervention, maintaining simplicity while achieving high adaptability through automated decision-making.
Solution Approach 2:
The system incorporates feedback loops that continuously monitor performance metrics and use this information to dynamically adjust the instrumentation scope. This feedback mechanism enables the system to adapt to changing conditions automatically, transitioning from static to adaptive scope management while maintaining operational simplicity through automated control.

AI summary
Embodiments of the present invention include systems and methods for dynamically adjusting instrumentation scope of a profiler gent. The method for dynamically adjusting an instrumentation scope of a profiler agent includes: supplying an initial instrumentation scope profile (ISP) that defines an instrumentation scope of a profiler agent to the profiler agent; receiving performance data of a call tree from the profiler agent based on the initial ISP; adjusting the instrumentation scope; updating the initial ISP based on the adjusted instrumentation scope; and supplying the updated ISP to the profiler agent. Adjusting the instrumentation scope includes at least one of expanding a child node of the call tree and excluding a child node of the call tree from the instrumentation scope.
