Trap Manager Daemon for Network Alert Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In complex networks with hundreds of devices from different vendors, network management applications receive thousands of traps, making it time-consuming and difficult for users to manually filter out uninteresting alerts, as existing solutions lack efficient mechanisms for managing and filtering these traps.
Innovation Solution
The introduction of a trap manager and trap daemon that provide an interface for managing trap filters, allowing users to configure and apply filters to selectively ignore unwanted traps, with features like super-filters and sub-filters to streamline the filtering process and automatically maintain configuration file consistency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually add filters to screen out uninteresting traps, then trap filtering capability is achieved, but time consumption and operational difficulty increase significantly
Solution Approach 1:
The system performs automatic trap filtering without requiring manual user intervention. The trap manager automatically analyzes received traps, identifies patterns, and applies appropriate filters based on predefined criteria and user preferences, making the filtering process self-service rather than manual
Solution Approach 2:
The system pre-configures filter templates and criteria before traps are received. By establishing filtering rules in advance based on common trap patterns and user interests, the system prepares the filtering mechanism beforehand, eliminating the need for time-consuming manual filter creation when traps arrive
2Ease of operation
If comprehensive trap filtering is implemented, then relevant trap management is improved, but system complexity increases
Solution Approach 1:
The trap manager acts as an intermediary component between the trap receiver and the user interface. It handles the complex filtering logic, template management, and trap analysis in the background, presenting a simplified interface to users while managing the complexity internally through the mediator pattern
Solution Approach 2:
The filtering system is divided into modular components: trap receiver, trap manager, filter templates, and user interface. Each component has a specific responsibility, allowing the complex filtering functionality to be broken down into manageable, independent modules that can be developed and maintained separately
