Port Monitoring
Monitor port availability for any service.
Databases, mail servers, game servers, custom TCP services -- monitor the availability of any port on any host from 200+ global edge locations.
TCP & UDP Support
Monitor both TCP and UDP ports. Check database connections, mail servers, DNS resolvers, game servers, and more.
Any Service, Any Port
MySQL (3306), PostgreSQL (5432), Redis (6379), SMTP (25/587), SSH (22) -- monitor any port on any host.
Connection Validation
Go beyond simple port checks. Validate that the service behind the port is actually responding correctly.
Latency Tracking
Track connection establishment times across regions. Spot degradation before it becomes an outage.
How it works
Specify host and port
Enter the hostname or IP address and port number. Choose between TCP and UDP protocols.
Connection checks
Edge workers attempt connections from multiple regions and verify port accessibility and response times.
Alert on failures
When consensus confirms a port is unreachable, you get notified via your preferred channels instantly.
