SSL Monitoring
exit1.dev automatically monitors SSL/TLS certificates for all HTTPS checks.
Automatic Monitoring
SSL monitoring is enabled by default for any check using an https:// URL. No additional configuration is required.
What’s Monitored
Certificate Details
exit1.dev tracks the following certificate information:
| Field | Description |
|---|---|
| Issuer | The Certificate Authority that issued the certificate |
| Subject | The domain the certificate is issued for |
| Valid From | Certificate start date |
| Valid To | Certificate expiration date |
| Serial Number | Unique certificate identifier |
| Fingerprint | Certificate fingerprint for verification |
Validation Checks
Each SSL check verifies:
- Certificate validity - Is the certificate currently valid?
- Certificate chain - Is the full chain of trust intact?
- Expiration - Is the certificate approaching expiration?
- Domain match - Does the certificate match the monitored domain?
Refresh Cycle
SSL certificate information is refreshed every 6 hours. This means:
- Certificate changes are detected within 6 hours
- Expiration warnings update every 6 hours
- New certificates are recognized after the next refresh cycle
SSL Alerts
SSL-related alerts include:
| Event | Description |
|---|---|
ssl_error | Certificate is invalid, expired, or has chain issues |
ssl_warning | Certificate is approaching expiration |
These alerts are sent through your configured alert channels (email, SMS, webhooks, Slack, Discord).
Best Practices
- Monitor all production HTTPS endpoints
- Set up alert channels to receive SSL warnings before certificates expire
- Use Domain Intelligence for additional domain expiration tracking
- Review certificate details periodically in the dashboard
