TCP monitoring: Definition & Details

What is the purpose of TCP monitoring?

The TCP monitoring report displays the cumulative efficiency of all TCP connections over time. It will wait for the TCP connection to be established for any TCP application before sending the request string and watching for the server to deliver the desired content. The health check will be successful as soon as a TCP connection has been established, even if no client request and server response are defined. 

In addition, application, internal host, and external host categories are all options for the report data. You may dive down onto certain hosts or apps to see how well they handle a certain type of traffic.

This report provides answers to issues like:

  • Do TCP inefficiencies cause the network delays we’re seeing?
  • Is a specific host or application experiencing issues as a result of retransmissions?

How does TCP monitoring perform?

Interoperable communication via the Internet between physically distinct computer systems is made possible by TCP/IP protocols. A TCP Monitor ensures the smooth operation of this communication process. Typically, the Transmission Control Protocol Monitoring process consists of the following three steps:

  1. Finding: To get a good view of your network traffic, you must first become familiar with your network, devices, and IP addresses. A network map can be made using tools like Server & Application Monitor.
  2. The following action is to regularly check your applications’ network connections to find any performance concerns.
  3. Troubleshooting: Now is the time to address any issues that arise using the knowledge that your TCP Monitoring system has gathered.

Which TCP Port to choose?

A device is connected to the network if we can ping it. The next step is to confirm that the device’s services are active. On a network device known as a port, all standard apps execute. These ports are either TCP or UDP.

You may determine whether the service is active on the network device by activating a TCP Check. For instance, a web server serves as the host for all websites. These web servers run on TCP Port 80 by default. So, by configuring a TCP Check on Port 80, we are determining whether the network device’s web server service is active. In addition, several TCP Ports are used for file transfers, such as File Transfer Protocol ports 20 and 21, SMTP port 25 and IMAP port 143 for emails, and Secure Shell port (22).

Most apps operating on a network device can be configured with TCP monitoring using a list of regularly used TCP and UDP port numbers.
