Hierarchical Hypervisor Performance Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Monitoring the performance of hypervisor systems is challenging due to their dynamic nature and complex architecture, which involves coordinating operations of multiple virtual machines and hosts.
Innovation Solution
The system represents the hypervisor architecture as a tree with nodes corresponding to system components, calculates performance numbers based on task completions and resource utilization, and assigns performance states using different criteria for various levels of components, allowing reviewers to drill down into performance metrics of underlying components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the hypervisor architecture is represented with detailed performance metrics for all components, then the completeness of performance information is improved, but the complexity of the interface and difficulty of interpretation increases
Solution Approach 1:
The hypervisor architecture is segmented into hierarchical levels (hypervisor level, host level, VM level) with each level displaying performance metrics appropriate to that level. The interface presents summarized performance data at each hierarchical level, allowing reviewers to access detailed information only when needed by drilling down into specific components.
Solution Approach 2:
The interface adds a hierarchical dimension to the presentation of performance data, organizing metrics across multiple levels (hypervisor → host → VM). This dimensional organization allows the same comprehensive information to be presented in a structured way that reduces perceived complexity while maintaining completeness.
2Reliability
If performance metrics for all system components are displayed simultaneously, then the completeness of monitoring information is improved, but the ease of operation and understanding decreases
Solution Approach 1:
The monitoring interface is segmented into hierarchical views where only relevant performance metrics for the current level are displayed prominently. Detailed metrics for all components are available but not simultaneously forced on the user, improving ease of operation while maintaining monitoring completeness through on-demand access.
Solution Approach 2:
The interface dynamically adapts its presentation based on user interaction. When a reviewer selects or drills down into a specific component, the interface dynamically expands to show detailed performance metrics for that component and its sub-components, providing comprehensive monitoring information only when and where needed.
3Measurement precision
If different performance criteria are used for different levels of components, then the precision of performance assessment is improved, but the consistency of evaluation methodology decreases
Solution Approach 1:
Different performance criteria and metrics are applied locally to each hierarchical level based on what is most relevant for that level. The hypervisor level uses criteria appropriate for overall system management, host levels use criteria for physical server performance, and VM levels use criteria for virtual machine efficiency, with each level's metrics tailored to its specific function.
Solution Approach 2:
The hierarchical performance monitoring system provides a universal framework that can assess performance across all levels (hypervisor, host, VM) using a consistent interface structure. While specific metrics differ by level, the overall evaluation methodology remains consistent through the unified hierarchical presentation and drill-down capability.

AI summary
Techniques promote monitoring of hypervisor systems by presenting dynamic representations of hypervisor architectures that include performance indicators. A reviewer can interact with the representation to progressively view select lower-level performance indicators. Higher level performance indicators can be determined based on lower level state assessments. A reviewer can also view historical performance metrics and indicators, which can aid in understanding which configuration changes or system usages may have led to sub-optimal performance.
