TCP Port monitoring allows you to check Internet services using monitoring agents from all over the world. ServerView Monitoring™ attempts to connect to your server on a specified port and verifies the connection. Whenever a connection to the port cannot be established, you are instantly notified.
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).
ServerView's 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.
