Database Performance Snapshot via Host Burden Adaptive Script Spawning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods lack a comprehensive, vendor-independent, and non-obtrusive mechanism for scripted collection and interpretation of performance metrics across multiple database vendors, storage, and hosts.
Innovation Solution
The solution involves obtaining a host burden rating based on processing, network, and I/O statistics to determine a spawn limit, spawning scripts to collect performance data specific to each database type, and presenting or storing this data with a graphical user interface or repository, using a HIRE agent and multi-loader agent to ensure non-intrusive data collection and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple scripts are spawned to collect comprehensive performance data across multiple database vendors and hosts, then the comprehensiveness and versatility of performance assessment is improved, but the host burden and system resource consumption increase
Solution Approach 1:
The system dynamically adjusts the number of script spawns based on real-time host burden rating. The host burden rating is calculated from processing, network, and I/O statistics, and the spawn limit is determined as a function of this rating. This dynamic adjustment allows the system to be comprehensive when host resources are abundant while minimizing burden when resources are constrained.
Solution Approach 2:
The system changes the parameter of script spawn count based on host performance conditions. By monitoring host statistics (CPU, network, I/O) and adjusting the spawn limit accordingly, the system optimizes the balance between comprehensive data collection and host burden, transforming a static configuration into an adaptive parameter.
2Measurement precision
If vendor-specific scripts are used to collect detailed performance metrics, then the measurement precision and completeness of database performance data is improved, but the device complexity and difficulty of maintenance increase
Solution Approach 1:
The system employs a universal script spawning mechanism that can execute vendor-specific scripts through a common interface. The host-aware script spawner selects and executes appropriate scripts based on database type and vendor, providing a unified approach to collecting performance metrics across different database systems without requiring separate management processes for each vendor.
Solution Approach 2:
The system implements self-service through automatic script selection and execution. The host-aware script spawner automatically identifies the appropriate database type and vendor, selects the corresponding script from the available scripts, and executes it without manual intervention. This eliminates the need for operators to manually manage and configure vendor-specific scripts.
3Reliability
If performance data collection is performed continuously and comprehensively, then the reliability and completeness of performance assessment is improved, but the host burden and potential disruption to database operations increase
Solution Approach 1:
The system performs partial data collection by spawning a limited number of scripts based on host burden rating rather than executing all possible collection tasks continuously. This partial action approach ensures sufficient performance assessment reliability while avoiding excessive resource consumption and operational disruption.
Solution Approach 2:
The system implements periodic performance data collection rather than continuous monitoring. By spawning scripts at intervals and adjusting the frequency based on host burden rating, the system maintains reliable performance assessment while reducing continuous host burden and minimizing potential disruption to database operations.
Data Source
AI summary
Methods and apparatus are provided for obtaining database performance snapshots. Performance data for one or more databases on a host is obtained by obtaining a host burden rating based on one or more of processing, network and input/out statistics of the host; determining a spawn limit based on the host burden rating; and spawning one or more scripts within the spawn limit, wherein each of the scripts collect performance data for a given database and is selected based on a database type of the given database. The host burden rating is a quantitative measure based on a sum of the processing, network and input/out statistics of the host. The collected performance data can be presented to a user in a graphical user interface and/or stored in a repository. The presented collected performance data for a given database comprises, for example, a score and/or a health assessment indicator based on predefined thresholds.
