The SDK embedded in your application continuously collects telemetry data:

• Performance Metrics: Page load times, Core Web Vitals (FCP, LCP, CLS, FID), resource timing
• Error Events: JavaScript exceptions, unhandled promise rejections, runtime errors with stack traces
• User Behavior: Page views, clicks, session duration, unique visitors, bounce rates
• Security Signals: Potential vulnerabilities (XSS, SQLi patterns), insecure headers, cookie analysis

Collected data is sent to the Sublyzer backend, where it undergoes:

• Deduplication: Similar errors and events are grouped by signature (message + stack trace)
• Aggregation: Metrics are aggregated by time windows (hourly, daily) for trend analysis
• Classification: Errors are categorized by severity (low, medium, high, critical)
• Pattern Detection: Security patterns (exploit attempts, suspicious payloads) are identified

The dashboard provides real-time analysis:

• Performance Dashboard: Visualizes load times, Core Web Vitals trends, and identifies slow pages
• Security Panel: Lists vulnerabilities, exploit attempts, and security recommendations
• User Analytics: Shows user growth, session metrics, device breakdown, geographic distribution
• Error Tracking: Displays error frequency, stack traces, affected files, and resolution status

Sublyzer uses AI to provide contextual analysis:

• Score Generation: Calculates performance, security, reliability, and UX scores (0-100)
• Recommendations: Suggests optimizations based on collected data patterns
• Trend Analysis: Identifies improvements or degradations over time
• Anomaly Detection: Flags unusual patterns that may indicate issues

For automated UI/UX and navigation testing, Sublyzer can run TestingAI: multiple headless browser agents (Playwright/Chromium) that navigate your site, stream logs, record videos per agent, and generate a visual analysis.

See: TestingAI Guide

The dashboard auto-refreshes every 10 seconds to show the latest data. Data is cached locally to prevent loss during network interruptions.

Sublyzer One stores your data securely:

• Raw Events: Stored for 90 days by default (configurable)
• Aggregated Metrics: Retained indefinitely for trend analysis
• Error Logs: Kept for 30 days with deduplication
• User Sessions: Stored for session analysis, anonymized after 7 days

You can export or delete all data at any time from Settings.

Sublyzer calculates multiple scores (0-100) to help you understand your application's health:

• Performance Score: Based on Core Web Vitals, load times, and resource efficiency
• Security Score: Evaluates vulnerabilities, security headers, and best practices
• Reliability Score: Measures error rates, uptime, and stability
• UX Score: Combines performance metrics with user behavior patterns
• Overall Health Score: Weighted average of all scores

Configure alerts to be notified of important events:

• Error Thresholds: Alert when error count exceeds a limit
• Performance Degradation: Notify if load times increase significantly
• Security Issues: Immediate alerts for critical vulnerabilities
• User Metrics: Track unusual patterns in user behavior

Alerts can be sent via email, Slack, Discord, or custom webhooks. Configure in Settings → Alertas.
