📦 Site Health Monitor — 技能工具

技能文档

Monitor one or more websites for health issues. Detect downtime, expiring SSL certs, slow responses, and content changes — then report or alert.

Quick Check (Single URL)

When user asks to check a single URL right now:

• Run scripts/check_site.sh
• Parse the JSON output
• Present a formatted health report

Monitored Sites Config

For ongoing monitoring, maintain a config at user's chosen location (default: ~/.openclaw/workspace/site-monitor.json):

{
  "sites": [
    {
      "url": "https://example.com",
      "name": "Main Site",
      "checks": ["uptime", "ssl", "response_time", "content"],
      "alert_threshold_ms": 3000,
      "ssl_warn_days": 14,
      "content_selector": "title"
    }
  ],
  "defaults": {
    "checks": ["uptime", "ssl", "response_time"],
    "alert_threshold_ms": 5000,
    "ssl_warn_days": 30
  }
}

Health Checks

1. Uptime

• HTTP GET to URL
• Pass: 2xx/3xx status
• Warning: 4xx status
• Fail: 5xx, connection refused, timeout (>10s)

2. SSL Certificate

• Run scripts/check_ssl.sh
• Pass: Valid, >30 days to expiry
• Warning: <30 days to expiry (configurable)
• Fail: Expired, self-signed, or missing

3. Response Time

• Measure TTFB + transfer via scripts/check_site.sh
• Pass: Under threshold (default 5000ms)
• Warning: 1-2x threshold
• Fail: >2x threshold or timeout

4. Content Changes (Planned)

• Fetch page, extract text, hash it
• Compare against stored hash
• Report if content changed since last check
• Note: This feature is planned for v1.1

Scheduled Monitoring

Suggest cron job for recurring checks (30-60 min interval for production). Store last 100 results per site in ~/.openclaw/workspace/.site-monitor-history.json.

Scripts

• scripts/check_site.sh — HTTP health check, outputs JSON (status, timing, headers)
• scripts/check_ssl.sh — SSL cert check, outputs JSON (issuer, expiry, days remaining)
