Port Monitoring FAQ
Common questions about TCP monitoring
Any TCP port from 1 to 65535. Common examples: SSH (22), HTTP (80), HTTPS (443), MySQL (3306), PostgreSQL (5432), MongoDB (27017), Redis (6379), SMTP (25, 587).
TCP monitoring tests basic connectivity only (can we connect?). For protocol-specific checks (can we login? query database?), contact us about custom monitoring.
Port monitoring won't work if your firewall blocks connections from our IPs. You'll need to whitelist our monitoring locations or use internal agent monitoring.
Free plan: every 5 minutes. Pro: every 1 minute. Business/Enterprise: every 1 minute or 30 seconds.
Connection refused, connection timeout, or TCP handshake failure. We don't inspect application-level responses—just TCP connectivity.
Currently no—only TCP ports. UDP monitoring is planned for future release. Contact us if you need it urgently.
Yes! Monitor both IPv4 and IPv6 TCP ports from our dual-stack monitoring locations.
