Log Information Collection Device for Network Failure Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network operation systems struggle to detect newly discovered failures that are not anticipated during program coding, as they only display specific log levels and miss patterns across multiple logs, which can indicate defects that require monitoring over multiple types of logs.
Innovation Solution
A log information collection apparatus and method that includes a condition determination unit to check for the occurrence of specific character strings within predetermined durations, generating new log information based on the occurrence or non-occurrence of these strings, allowing for the detection of defects that would otherwise be missed by only displaying specific log levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If only specific log levels are displayed on the monitoring screen, then the operator can easily monitor the system, but newly discovered failures that require monitoring multiple log types cannot be detected
Solution Approach 1:
The patent introduces a log analysis device as an intermediary between the network operation system and the operator. This device automatically analyzes multiple log types, synthesizes patterns, and generates synthesized logs that highlight potential failures. The operator monitors only the synthesized logs through the monitoring screen, while the analysis device handles the complex multi-log analysis in the background, thus maintaining ease of operation while improving failure detection capability
Solution Approach 2:
The patent creates synthesized logs that are copies or representations of patterns detected across multiple original log types. Instead of requiring the operator to examine numerous individual log entries, the system generates condensed synthesized logs that capture essential failure patterns, reducing the monitoring burden while maintaining detection accuracy
2Loss of information
If the frequency of log information output is increased, then more information is available for problem analysis, but the rate of log accumulation becomes larger making it harder to detect important logs
Solution Approach 1:
The patent extracts and isolates only the essential failure patterns from the large volume of accumulated logs by analyzing multiple log types simultaneously. The log analysis device identifies and extracts meaningful patterns, generating synthesized logs that contain only the critical information needed for failure detection, thus maintaining high information availability while reducing management complexity
Solution Approach 2:
The patent changes the parameter of log information from raw, unprocessed log entries to synthesized, pattern-based log representations. By transforming the log data through automatic analysis and pattern recognition, the system maintains comprehensive information for analysis while presenting a simplified, more manageable form to the operator

AI summary
Disclosed herein are log information collection methods for collecting log information of a network device operating in accordance with instructions from an operation apparatus. In some cases, the log information collection method can comprise: determining whether another piece of the log information including a second character string occurs in a predetermined duration, wherein the niece of log, information includes a first character string; generating a new piece of log information including a third character string; and accepting specifications of the first, second, and third character strings, the predetermined duration, and occurrence or non-occurrence of the piece of the log information and the other piece of the log information.
