What is TCP Port Monitoring?

TCP is the most commonly used protocol on the Internet. The Port Availability monitor checks to see if a device is listening for and accepting connections on a specified TCP port.

Monitoring agents attempt to connect to your server through the specified port and then verifies the connection. When a connection to the port cannot be established, our monitoring agents will alert you instantly via email, SMS text, wireless email, phone or through your SNMP console.

Monitor Server Ports via TCP

On your network, server ports are identified by number. Ports are resources allocated to various applications running on the host network that communicates with applications running – on the same host or on other network hosts.

In a typical client-server model an application waits for incoming data (or the connection request, “Listening TCP port”; the role of server), or sends data (or the connection request) to the known TCP port, opened by the application server (client role).

TCP-based port monitoring will let you know whenever port connectivity becomes an issue. You’ll receive an instant alert when a port cannot be reached – along with diagnostic information to help you quickly address the cause of connectivity failure.
