Metadata

name: site-health-monitor
description: Monitor websites for uptime, SSL certificate expiry, response time, HTTP errors, and content changes. Generate health reports and send alerts when issues are detected. Use when asked to monitor a website, check site health, track uptime, verify SSL certificates, detect downtime, set up website monitoring, check if a site is up, or audit website performance. Triggers on "monitor site", "check uptime", "SSL expiry", "is my site up", "website health", "site status", "monitor URL", "check website".

Site Health Monitor

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 <url>
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 <domain>
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

Alerts

Alert when: site DOWN, SSL within warning window, response >2x threshold, 2+ consecutive failures.

Format: ⚠️ [site] — [issue]. [detail]. Checked at [time].

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 <url> — HTTP health check, outputs JSON (status, timing, headers)
scripts/check_ssl.sh <domain> — SSL cert check, outputs JSON (issuer, expiry, days remaining)
