Backend Improvements (11 fixes applied): Critical Fixes: - Add lock protection for browser pool access in monitor stats - Ensure async track_janitor_event across all call sites - Improve error handling in monitor request tracking (already in place) Important Fixes: - Replace fire-and-forget Redis with background persistence worker - Add time-based expiry for completed requests/errors (5min cleanup) - Implement input validation for monitor route parameters - Add 4s timeout to timeline updater to prevent hangs - Add warning when killing browsers with active requests - Implement monitor cleanup on shutdown with final persistence - Document memory estimates with TODO for actual tracking Frontend Enhancements: WebSocket Real-time Updates: - Add WebSocket endpoint at /monitor/ws for live monitoring - Implement auto-reconnect with exponential backoff (max 5 attempts) - Add graceful fallback to HTTP polling on WebSocket failure - Send comprehensive updates every 2 seconds (health, requests, browsers, timeline, events) UI/UX Improvements: - Add live connection status indicator with pulsing animation - Green "Live" = WebSocket connected - Yellow "Connecting..." = Attempting connection - Blue "Polling" = Fallback to HTTP polling - Red "Disconnected" = Connection failed - Restore original beautiful styling for all sections - Improve request table layout with flex-grow for URL column - Add browser type text labels alongside emojis - Add flex layout to browser section header Testing: - Add test-websocket.py for WebSocket validation - All 7 integration tests passing successfully Summary: 563 additions across 6 files
