Composite Request Error Detection via Operation-Level Status Codes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Monitoring tools that rely on HTTP status codes struggle to accurately detect server errors in composite request systems, where a single request can involve multiple operations and server-side resources, as they typically return a single HTTP status code, masking failures in individual operations.
Innovation Solution
A computer-implemented method generates a composite response by executing operations, receiving execution result data, determining status codes for each operation, and associating these status codes with the operation response data, allowing for detailed error reporting in composite request systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single HTTP status code is returned for composite requests, then the response format remains simple and compatible with standard monitoring tools, but the ability to detect errors in individual operations is lost
Solution Approach 1:
The patent segments the single HTTP status code into multiple operation-level status codes, where each operation in the composite request receives its own status code. This segmentation enables monitoring tools to detect errors in individual operations while maintaining the overall composite response structure.
Solution Approach 2:
The patent embeds operation-level status codes within the composite response structure, creating a nested hierarchy where the composite response contains individual operation results, each with its own status code. This nesting allows detailed error information to be contained within the standard response framework.
2Measurement precision
If multiple status codes are provided for each operation, then monitoring precision improves, but the complexity of processing and interpreting responses increases
Solution Approach 1:
The patent applies local quality by providing status codes at the specific level where they are needed - each operation receives its own status code rather than a single global status code. This local differentiation enables precise monitoring of individual operations without requiring complex global interpretation.
Solution Approach 2:
The patent implements feedback by returning status codes for each operation that provide immediate information about execution results. This feedback mechanism allows monitoring tools to automatically interpret operation outcomes without complex processing, as each status code clearly indicates success or failure of its corresponding operation.
3Reliability
If detailed operation-level status information is provided, then server error detection improves, but the data processing overhead increases
Solution Approach 1:
The patent enables self-service by having each operation automatically generate its own status code based on its execution result. This eliminates the need for complex centralized processing to determine operation outcomes, as each operation provides its own status information directly in the response.
Solution Approach 2:
The patent changes the status code parameter from a single global value to multiple operation-specific values. This parameter transformation allows detailed error detection while keeping processing overhead low, as the status codes are generated directly by each operation during normal execution rather than requiring additional analysis.
Data Source
AI summary
Described herein is a computer implemented method for generating a composite response. The method comprises receiving a composite request defining one or more operations and generating a composite response by, for each operation: executing the operation using one or more server side resources; receiving execution result data; writing operation response data to the composite response; determining a status code providing information on at least one of the one or more server side resources used to execute the operation; and associating the status code with the operation response data in the composite response.
