Solution Overview

Problem

Existing systems for monitoring real-time software in target environments face inefficiencies in locating areas of interest within extensive event data logs, as maximum zoom views are slow to render and often display too much information, making it difficult to navigate and analyze dense activity sections.

Innovation Solution

The method involves displaying a schematic representation of event data over a monitoring period alongside a detailed graphical representation of a specified portion, using different scales to facilitate quick location and analysis of areas of interest within the data, allowing users to efficiently navigate and focus on specific sections without rendering the entire detailed graph.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the maximum level zoom view of the entire log is displayed to obtain an overview, then the user can locate areas of interest, but the view is slow to render and displays too much information

Engineering Contradiction:
Improvenavigation efficiencyVSAvoidrendering time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent divides the event data log into two distinct graphical representations: a schematic overview display showing the entire monitoring period with aggregated activity density, and a detailed display showing a specific portion of the log. This segmentation allows users to quickly navigate using the simplified overview without the performance penalty of rendering all detailed data, while still accessing comprehensive information when needed.

Inventive Principle:
Principle #1Segmentation

2Loss of information

If the maximum level zoom view displays all contexts, then complete information is available, but the information may not fit on the screen vertically

Engineering Contradiction:
Improveinformation completenessVSAvoidscreen display area
Core Design Contradiction:
Loss of informationVSArea of stationary object

Solution Approach 1:

The patent extracts and displays only aggregated activity density information in the schematic overview representation, omitting individual context details. This extraction allows the overview to fit within the screen display area while preserving the ability to access complete context information in the detailed display when users navigate to specific portions of interest.

Inventive Principle:
Principle #2Taking out (Extraction)

3Measurement precision

If a detailed graphical representation of the entire log is rendered, then complete analysis is possible, but navigation and identification of areas of interest becomes difficult

Engineering Contradiction:
Improveanalysis detailVSAvoidnavigation efficiency
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent applies different levels of detail to different parts of the interface: the schematic overview display uses aggregated, low-detail representation for efficient navigation across the entire log, while the detailed display provides high-detail context information for specific portions. This local quality differentiation allows users to navigate efficiently at the overview level and access precise analysis details when needed, without the navigation burden of displaying all details uniformly.

Inventive Principle:
Principle #3Local quality

AI summary

A system and method for providing an overview of a plurality of tasks running on a target environment which includes the steps of receiving event data representing a plurality of events in the plurality of contexts over a monitoring period displaying a detailed graphical representation of the event data log using the event data, and displaying a schematic representation of the detailed graphical representation over the monitoring period using only a portion of the event data. The schematic representation is indicative of an activity density of the event data over the monitoring period.
