From e2af031b09aab445ae6969010994f5344e8e03a7 Mon Sep 17 00:00:00 2001 From: unclecode Date: Fri, 17 Oct 2025 21:36:25 +0800 Subject: [PATCH] feat(monitor): add real-time monitoring dashboard with Redis persistence MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Complete observability solution for production deployments with terminal-style UI. **Backend Implementation:** - `monitor.py`: Stats manager tracking requests, browsers, errors, timeline data - `monitor_routes.py`: REST API endpoints for all monitor functionality - GET /monitor/health - System health snapshot - GET /monitor/requests - Active & completed requests - GET /monitor/browsers - Browser pool details - GET /monitor/endpoints/stats - Aggregated endpoint analytics - GET /monitor/timeline - Time-series data (memory, requests, browsers) - GET /monitor/logs/{janitor,errors} - Event logs - POST /monitor/actions/{cleanup,kill_browser,restart_browser} - Control actions - POST /monitor/stats/reset - Reset counters - Redis persistence for endpoint stats (survives restart) - Timeline tracking (5min window, 5s resolution, 60 data points) **Frontend Dashboard** (`/dashboard`): - **System Health Bar**: CPU%, Memory%, Network I/O, Uptime - **Pool Status**: Live counts (permanent/hot/cold browsers + memory) - **Live Activity Tabs**: - Requests: Active (realtime) + recent completed (last 100) - Browsers: Detailed table with actions (kill/restart) - Janitor: Cleanup event log with timestamps - Errors: Recent errors with stack traces - **Endpoint Analytics**: Count, avg latency, success%, pool hit% - **Resource Timeline**: SVG charts (memory/requests/browsers) with terminal aesthetics - **Control Actions**: Force cleanup, restart permanent, reset stats - **Auto-refresh**: 5s polling (toggleable) **Integration:** - Janitor events tracked (close_cold, close_hot, promote) - Crawler pool promotion events logged - Timeline updater background task (5s interval) - Lifespan hooks for monitor initialization **UI Design:** - Terminal vibe matching Crawl4AI theme - Dark background, cyan/pink accents, monospace font - Neon glow effects on charts - Responsive layout, hover interactions - Cross-navigation: Playground ↔ Monitor **Key Features:** - Zero-config: Works out of the box with existing Redis - Real-time visibility into pool efficiency - Manual browser management (kill/restart) - Historical data persistence - DevOps-friendly UX Routes: - API: `/monitor/*` (backend endpoints) - UI: `/dashboard` (static HTML) --- deploy/docker/crawler_pool.py | 28 +- deploy/docker/monitor.py | 305 ++++++++ deploy/docker/monitor_routes.py | 322 ++++++++ deploy/docker/server.py | 42 ++ deploy/docker/static/monitor/index.html | 813 +++++++++++++++++++++ deploy/docker/static/playground/index.html | 13 +- 6 files changed, 1516 insertions(+), 7 deletions(-) create mode 100644 deploy/docker/monitor.py create mode 100644 deploy/docker/monitor_routes.py create mode 100644 deploy/docker/static/monitor/index.html diff --git a/deploy/docker/crawler_pool.py b/deploy/docker/crawler_pool.py index 226e3680..95593b3f 100644 --- a/deploy/docker/crawler_pool.py +++ b/deploy/docker/crawler_pool.py @@ -57,6 +57,14 @@ async def get_crawler(cfg: BrowserConfig) -> AsyncWebCrawler: if USAGE_COUNT[sig] >= 3: logger.info(f"⬆️ Promoting to hot pool (sig={sig[:8]}, count={USAGE_COUNT[sig]})") HOT_POOL[sig] = COLD_POOL.pop(sig) + + #
