Enterprise Alert Management System Duplicate Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional alert management systems generate a high volume of duplicate alerts, making it cumbersome and time-consuming to resolve anomalies, and increasing the likelihood of missing critical alerts, which can lead to operational failures in enterprise environments.
Innovation Solution
The system discards duplicate alerts by analyzing past alert data to determine duplicate alert arrival times and periodicity, generates alert correlation and temporal signatures, and transmits only legitimate alerts to computing devices for resolution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the alert management system generates alerts for every anomaly detected, then the completeness of anomaly detection is improved, but the volume of duplicate alerts increases making resolution cumbersome and time-consuming
Solution Approach 1:
The system performs preliminary analysis of alert patterns by analyzing historical alert data to establish baseline behavior and anomaly patterns before new alerts are generated. This preliminary understanding enables the system to pre-identify potential duplicate alerts and correlate them with existing unresolved alerts, preventing redundant alert generation and reducing the time required for resolution.
Solution Approach 2:
The system implements a feedback mechanism where generated alerts are continuously correlated with existing alerts and historical patterns. The correlation engine provides feedback by identifying duplicate alerts based on similarity analysis of alert characteristics, time patterns, and source information. This feedback loop enables real-time filtering of duplicate alerts while maintaining detection of genuine new anomalies.
2Loss of information
If the alert management system transmits all generated alerts to computing devices, then the information completeness is improved, but the likelihood of missing critical alerts increases due to high volume
Solution Approach 1:
The system extracts and removes duplicate alerts from the alert stream by comparing each generated alert against existing alerts and historical patterns. The correlation engine identifies and extracts redundant information by analyzing alert characteristics, time patterns, and source correlations, transmitting only the essential unique alerts to computing devices while filtering out duplicates.
Solution Approach 2:
The system changes the parameters of alert transmission by introducing correlation-based filtering criteria. Instead of transmitting all alerts uniformly, the system applies parameter changes such as time-based correlation windows, similarity thresholds, and pattern matching parameters to differentiate between duplicate and critical alerts, ensuring reliable detection of genuine anomalies.
3Difficulty of detecting and measuring
If the alert management system monitors all enterprise resources continuously, then the detection capability is improved, but the system complexity and computational requirements increase
Solution Approach 1:
The system segments the alert analysis process into distinct functional modules: alert generation, historical data retrieval, correlation analysis, duplicate identification, and transmission. Each module handles specific aspects of alert management independently, reducing overall system complexity while maintaining comprehensive detection capability across all enterprise resources.
Solution Approach 2:
The system performs preliminary organization and indexing of historical alert data before correlation analysis is needed. By pre-processing and structuring historical data with appropriate indexes and patterns, the system reduces computational requirements during real-time alert correlation while maintaining comprehensive detection capabilities.

AI summary
A method for managing alerts generated in an enterprise environment is described. The method comprises discarding, by a processor, one or more duplicate alerts based on one or more predetermined rules, wherein a duplicate alert is an instance of an alert occurring within a duplicate alert arrival time associated with the alert. The method further comprises obtaining an alert correlation signature associated with the alert from a database, wherein the alert correlation signature comprises information associated with one or more alerts correlated to the alert. The method further comprises, obtaining, from the database, a temporal signature associated with the alert, wherein the temporal signature indicates a probable time of occurrence of the alert. Further, the alert, the alert correlation signature, and the temporal signature are transmitted to a computing device of a user of the enterprise environment.
