TCP Port Monitoring & Connection Health
Monitor TCP ports, database servers, mail services, and backend infrastructure 24/7. Verify connection health, track availability, and get instant alerts when ports become unreachable or services fail.
Comprehensive TCP Monitoring Features
Everything you need to monitor TCP services and infrastructure
Port Availability
Monitor TCP port availability and connection health. Track open/closed ports and detect unauthorized port changes instantly.
Fast Detection
Get alerts within seconds when TCP ports become unreachable or connections fail. Minimize service disruptions with rapid detection.
Connection Validation
Validate TCP connections and handshakes. Ensure services are accepting connections and responding correctly to requests.
Service Monitoring
Monitor databases, mail servers, FTP, SSH, and custom TCP services. Verify backend infrastructure is accessible and healthy.
Performance Metrics
Track connection times, handshake latency, and response delays. Identify network issues and optimize service performance.
Smart Alerting

TCP Monitoring Use Cases
Essential for any TCP-based infrastructure and services
Database Monitoring
Monitor PostgreSQL, MySQL, MongoDB, Redis, and other database servers. Ensure database ports are accessible and accepting connections. Detect database outages, network issues, and connection pool problems before they impact your applications.
Mail Server Monitoring
Monitor SMTP, IMAP, and POP3 ports to ensure email services remain online. Track mail server availability and connection health. Critical for businesses relying on email infrastructure and preventing email delivery disruptions.
Backend Services
Monitor custom TCP services, microservices, and internal APIs. Verify that backend infrastructure is accessible from your application servers. Essential for maintaining service reliability in distributed architectures.
Infrastructure Monitoring
Monitor SSH, FTP, SFTP, and other infrastructure services. Ensure remote access remains available and track connection health. Perfect for DevOps teams managing servers and network infrastructure.
