Solution Overview

Problem

Existing log management systems in information processing apparatuses face challenges in efficiently managing log storage when the frequency of file operations is high, leading to potential data size exceedance of the storage limit, necessitating manual administrator intervention which is time-consuming and inefficient.

Innovation Solution

Implementing a system that automatically transfers log information to an external log server and creates links for client access, while deleting unnecessary logs to manage storage space effectively.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If log information is stored in the information processing apparatus, then log history can be retained and referenced, but the storage area will be exhausted when the upper limit is reached, requiring manual intervention

Engineering Contradiction:
Improvelog storage capacityVSAvoidmanual log management burden
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The system automatically determines whether to store log information based on the presence of external destination settings (log server transfer or client PC link creation). When such settings exist, the system self-manages log storage by deleting local copies, eliminating the need for manual administrator intervention to clean up log storage space.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system continuously monitors storage settings and log volume, using this feedback to automatically adjust storage behavior. When a log server transfer or link creation is configured, the system detects this state and automatically prevents excessive local storage, creating a closed-loop control system that adapts to operational requirements.

Inventive Principle:
Principle #23Feedback

2Adaptability or versatility

If log transfer to external server is configured, then centralized log management is achieved, but local storage space is reduced

Engineering Contradiction:
Improvelog management flexibilityVSAvoidlocal log storage space
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The system extracts log information from local storage and transfers it to external destinations (log servers or client PCs). By removing logs from the information processing apparatus and storing them externally, the system achieves centralized log management while freeing up local storage space for other purposes.

Inventive Principle:
Principle #2Taking out (Extraction)

3Productivity

If frequent file operations are performed, then system productivity increases, but log data size exceeds storage limit more quickly

Engineering Contradiction:
Improvefile operation frequencyVSAvoidlog data volume
Core Design Contradiction:
ProductivityVSQuantity of substance

Solution Approach 1:

The system extracts and removes log data from local storage after successful transfer to external destinations. This extraction mechanism allows the system to handle frequent file operations and generate large volumes of logs without being constrained by limited local storage capacity, as logs are continuously moved to external storage.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

An information processing apparatus includes a storage device and is configured to output a notification message in response to available space of a log storage area of the storage device falling below a predetermined amount due to log information stored in the storage device, to set a first setting for transferring the log information stored in the log storage area to an external log server over a network and a second setting for creating a link for referring to the log information stored in the log storage area, and to perform control, in accordance with log transfer in accordance with the first setting and link creation in accordance with the second setting, so that a history record of a file operation is not stored as the log information in the log storage area.
