Feature Modules

The Web module focuses on webpage user experience and stability monitoring, supporting full-chain observation capabilities from page loading, user operations, and network requests to frontend exceptions, helping development and operations personnel locate core performance bottlenecks and business anomalies in Web pages.

Overview​

  • Core Functions: Core metrics display, page anomaly alerts, performance trend overview
  • Main Metrics: Traffic trends, key performance indicators (FP, FCP, TTI, page load time), number of exceptions, Apdex index
  • Application Scenarios: Product monitoring dashboard, daily quality inspection

Page Performance​

  • Core Functions: Page loading performance and stability analysis
  • Monitoring Metrics: Page loading time, blank screen time, page rendering time, time to first interaction
  • Analysis Capabilities: Page path aggregation, version comparison, anomaly distribution
  • Application Scenarios: First-screen experience optimization, high time-consuming page discovery, page retention analysis

Route Analysis​

  • Monitoring Object: Single-page application (SPA) frontend route transitions
  • Core Metrics: Route transition time, route hit path, transition failure rate
  • Application Scenarios: Frontend routing mechanism optimization, page transition experience improvement

Operation Monitoring​

  • Monitoring Object: User interaction behaviors (button clicks, tab switching, form inputs, etc.)
  • Core Metrics: Operation frequency, time consumption, response success rate
  • Special Features: User operation process restoration
  • Application Scenarios: Event tracking verification, button response analysis, interaction process optimization

Request Analysis​

  • Monitoring Content: Page network request performance
  • Core Metrics: Interface response time, failure rate, request distribution, slow interface list
  • Analysis Dimensions: Host, interface path, status code, request method
  • Application Scenarios: Interface response optimization, high latency/high failure rate interface investigation

Blank Screen Monitoring​

  • Monitoring Focus: Page loading blank screen issues
  • Core Metrics: Blank screen time, blank screen occurrence rate, number of affected users
  • Analysis Dimensions: Device/version/region distribution
  • Special Features: Anomaly restoration and tracing
  • Application Scenarios: Resource loading exceptions, JS initialization error location

JS Error Analysis​

  • Monitoring Object: JavaScript exceptions (runtime errors, resource loading errors, cross-domain script errors)
  • Core Functions:
    • Stack information parsing
    • Error aggregation analysis
    • User impact statistics
    • Exception trend analysis
    • User operation trajectory association
  • Application Scenarios: Daily monitoring and problem fixing for frontend development and QA teams

User Tracking​

  • Core Functions: Complete link retrieval based on user identification or session ID
  • Tracking Scope: Key events such as page loading, operations, requests, JS errors, etc.
  • Application Scenarios:
    • User complaint backtracking
    • Exception sample reproduction
    • Personalized user experience analysis
