Solution Overview

Problem

Existing log file management systems face challenges in accurately reconstructing the order of events leading to system failures or security breaches due to inconsistent time stamps, as local time stamps from data sources may not reflect the actual time of data receipt and can vary across different time zones.

Innovation Solution

A system that connects to data sources and adds both an independent time stamp and a sequence indicator to log data, providing a consistent timestamp and order of receipt, respectively, to ensure accurate event reconstruction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If local time stamps from data sources are used, then each system can maintain its own time zone and operational independence, but the consistency and accuracy of event timing across the network deteriorates

Engineering Contradiction:
Improvetime zone independenceVSAvoidevent timing consistency
Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent introduces a central monitoring system as an intermediary that receives data from multiple data sources and assigns centralized time stamps. This mediator reconciles the time zone differences by providing a common reference time (such as UTC) for all events, while still allowing data sources to maintain their local time zones for operational purposes. The centralized timestamping mechanism acts as the mediating element that resolves the contradiction between local independence and global consistency.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent adds a temporal dimension by introducing sequence indicators alongside time stamps. This creates a multi-dimensional time representation where events are ordered not only by their timestamp values but also by their sequence of arrival at the monitoring system. This additional dimensional approach allows for more precise event reconstruction even when time stamps alone are insufficient due to time zone variations or clock synchronization issues.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Productivity

If data from multiple systems is collected simultaneously, then comprehensive monitoring coverage is achieved, but the accuracy of reconstructing event sequence deteriorates due to inconsistent time stamps

Engineering Contradiction:
Improvemonitoring coverageVSAvoidevent sequence accuracy
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The central monitoring system serves as a mediator that receives data packets from multiple data sources simultaneously and processes them through a standardized timing mechanism. The intermediary assigns centralized time stamps and sequence indicators to each received data packet, ensuring that even though data arrives concurrently from multiple sources, the reconstructed event sequence maintains accuracy. This mediator approach allows comprehensive monitoring coverage while preserving event sequence integrity.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent implements preliminary timing actions by assigning time stamps and sequence indicators at the moment data is received at the monitoring system, before any further processing or analysis occurs. This preliminary timestamping ensures that the time reference is captured at the earliest possible point, preventing any subsequent processing delays from affecting the accuracy of event sequencing. The sequence indicator is also assigned preliminarily based on arrival order, ensuring accurate reconstruction.

Inventive Principle:
Principle #10Preliminary action

3Device complexity

If only time stamps are used for logging, then the logging mechanism remains simple, but the ability to accurately reconstruct events deteriorates when time stamps are inconsistent

Engineering Contradiction:
Improvelogging mechanism simplicityVSAvoidevent reconstruction accuracy
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent segments the timing information into two distinct components: time stamps and sequence indicators. Rather than relying on a single complex timestamp field, the solution divides the timing data into the actual timestamp value and a separate sequence number that indicates the order of arrival. This segmentation allows the logging mechanism to remain relatively simple while significantly improving event reconstruction accuracy, as the sequence indicator provides additional ordering information that compensates for timestamp inconsistencies.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent creates a composite timing mechanism by combining time stamps and sequence indicators into a unified logging approach. Rather than using a single type of time reference, the solution composite two different timing elements (the timestamp value and the sequence indicator) to create a more robust event identification system. This composite approach maintains logging simplicity while enhancing reliability, as the two components work together to provide accurate event reconstruction even when individual elements have limitations.

Inventive Principle:
Principle #40Composite materials

AI summary

In certain embodiments, a method for log file time sequence stamping is provided. The method includes connecting to a console port of one or more data sources and receiving data from the data sources. The data may be logged with both an independent time stamp and a sequence indicator. The independent time stamp provides a consistent time stamp of when the data was received at the system and the time sequence indicator represents an order in which the data was received at the system.
