Any TCP port
PostgreSQL on 5432, Redis on 6379, SMTP on 25, SSH on 22 — monitor any port on any host.
Connection time tracking
Measure TCP handshake latency over time. Spot network degradation before it causes timeouts.
Database monitoring
Verify your database is accepting connections without needing credentials or query-level access.
Service health checks
Confirm critical infrastructure services are reachable. If the port is closed, you know instantly.
Uptrack vs the alternatives
TCP monitoring should be a baseline feature, not an upsell.

How TCP monitoring works
Uptrack opens a TCP connection to your host and port at every check interval. A successful TCP handshake means the service is accepting connections. A timeout or refused connection triggers an alert. No agents, no credentials, no firewall changes needed — just a reachable port.
