Automated Error Image Extraction from Terminal Operation Logs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In information processing systems, it is challenging to efficiently extract moving image data at the time of error occurrence during automated screen operations, as recorded data includes images from both error and non-error screen operations, making it difficult for users to identify the cause of errors.
Innovation Solution
A process that determines the presence of an error log in the operation log, specifies the start and stop timings of the script associated with the error log, and extracts moving image data based on this timing information to isolate the image data relevant to the error occurrence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all log data and moving image data are stored for error analysis, then complete error investigation information is available, but data storage volume and processing time increase significantly
Solution Approach 1:
The patent extracts and stores only the specific moving image data corresponding to error logs, separating it from the entire operation log. When an error occurs, the system identifies the error log entry and extracts only the associated moving image segment, storing it in a dedicated error image storage area. This extraction principle reduces storage volume while preserving essential error investigation information.
Solution Approach 2:
The patent segments the continuous moving image data into discrete segments associated with individual script executions and error events. Each error log entry is linked to its corresponding moving image segment through timing information, creating modular, independently storable units. This segmentation enables efficient storage and retrieval of only relevant error data rather than processing entire continuous video streams.
2Loss of information
If all operation logs are reviewed to find error-related image data, then complete error context is captured, but time to locate and analyze errors increases
Solution Approach 1:
The patent implements a feedback mechanism where error logs automatically trigger the retrieval and display of corresponding moving image segments. When an error log is detected, the system uses the log's timing information to retrieve the associated image data and presents it to the user. This automated feedback loop eliminates manual searching and directly provides relevant error context, significantly reducing analysis time.
Solution Approach 2:
The patent replaces the mechanical process of manually reviewing operation logs with an automated information processing system. The system automatically correlates error logs with moving image data using timing information, retrieves the relevant segments, and displays them without human intervention. This substitution of automated processing for manual review dramatically reduces the time required to locate and analyze errors.
3Measurement precision
If detailed timing information is recorded for each log entry, then precise image data extraction is enabled, but log data complexity and processing overhead increase
Solution Approach 1:
The patent implements a universal timing information structure that serves multiple functions simultaneously. The same timing data embedded in log entries is used for both tracking script execution sequences and precisely identifying corresponding moving image segments. This multi-functional timing mechanism enables accurate image extraction without requiring separate complex tracking systems, reducing overall processing complexity while maintaining precision.

AI summary
A non-transitory computer-readable storage medium storing a program that causes a computer to execute a process, the process includes determining whether an error log is included in an operation log over a terminal; when the error log is included in the operation log, specifying a start timing and a stop timing of a script including the error log stored in a memory based on the operation log; and extracting moving image data output to the terminal during execution of the script based on time information related to the specified start timing and stop timing of the script.
