Comprehensive TCP Service Monitoring
TCP monitoring establishes connections to your services and verifies they respond correctly. Monitor databases, mail servers, custom applications, and any service using TCP protocol.
Key Features
Protocol Support
Monitor MySQL, PostgreSQL, Redis, MongoDB, and other TCP-based services.
Response Timing
Measure connection establishment time and service response latency.
Custom Checks
Send custom commands and verify expected responses for advanced validation.
Frequently Asked Questions
TCP monitoring checks if a service can establish a TCP connection on a specific port. Unlike ping (ICMP), TCP monitoring confirms the application layer is working. It verifies the server accepts connections, the service is running, and the network path is clear.
Use TCP monitoring for non-HTTP services: databases (MySQL, PostgreSQL), message queues (RabbitMQ, Redis), email servers (SMTP), FTP servers, SSH, or custom TCP services. HTTP monitoring is better for web applications since it validates response codes and content.
Yes. TCP monitoring measures connection time. If a service is overloaded, it may accept connections slowly or timeout. Monitoring tracks these delays and alerts when connection times exceed thresholds, indicating performance degradation.
Common causes: service crashed and port closed, firewall blocking connections, network routing issues, server resource exhaustion preventing new connections, or service hitting connection limits. TCP monitoring detects all these failure modes.
TCP is connection-oriented and requires handshake confirmation. UDP is connectionless—packets are sent without delivery confirmation. TCP monitoring is more reliable for detecting service availability since it verifies the service responds correctly.
