Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In the development phase of service systems, log messages generated during failures are not easily understandable for handling, especially when transitioning between development and operations phases, leading to unclear methods for addressing issues across different teams.

Innovation Solution

A management system that links log chunks and issue chunks from the development phase to provide handling methods for issues detected in the operations phase by using log pattern matching and masking environmentally-dependent message items.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If log messages are output and accumulated in the development phase, then failure detection capability is improved, but handling method understandability deteriorates

Engineering Contradiction:

Improvefailure detection capabilityVSAvoidhandling method understandability

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent introduces a management system as an intermediary between the development team and operations team. This system stores handling methods in association with log messages and automatically retrieves them when log messages are input, bridging the gap between raw log data and actionable troubleshooting guidance without requiring direct human intervention or manual documentation

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system enables self-service by automatically matching input log messages with stored handling methods through pattern matching. When a log message is input, the system autonomously retrieves and presents the corresponding handling method without requiring manual lookup or interpretation, allowing operations personnel to independently resolve issues

Inventive Principle:

Principle #25Self-service

2Adaptability or versatility

If log messages from different teams are shared, then collaborative troubleshooting is improved, but information matching accuracy deteriorates

Engineering Contradiction:

Improvecollaborative troubleshootingVSAvoidinformation matching accuracy

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent transforms log messages into a standardized format with extracted key parameters and characteristics. By normalizing the representation of log messages from different teams into common parameters, the system enables accurate pattern matching across team boundaries while preserving the essential diagnostic information needed for troubleshooting

Inventive Principle:

Principle #35Parameter changes

AI summary

A management system constructs management information indicating that log chunks and issue chunks extracted from a first system managing log information and issue information output by a process related to a first team for a program to be developed are linked. The management system searches, from the management information, a log message group compatible with a designated log message group that is one or more log messages related to the issue by log pattern matching using the designated log message group in a case of receiving an inquiry with which the designated log message group is associated from the second system. The management system displays, on the second system, a response containing a handling method represented by handling method information corresponding to the found log message group.
