SSL Monitoring

How It Works

SSL monitors check your hostname’s TLS certificate and alert you before it expires.

Setup

1. Create a monitor with type SSL
2. Enter the hostname (e.g. example.com) — no https:// prefix needed
3. Set SSL Warn Days — how many days before expiry to alert (default 30)
4. Set the check interval (daily is usually sufficient: 24 hours = 86400 seconds)

What’s Checked

• TLS handshake to port 443
• Certificate expiry date
• Alerts when the certificate expires within the configured warn period

Recommendations

• Set warn days to 30 for production domains (gives time to renew)
• Set warn days to 7 for staging/dev (less urgent)
• Check interval of 1 hour is sufficient for SSL monitoring
