TCP Monitoring – Everything you need to know

When you run an online business, you want to be sure that it stays online. So there is no better way than to set up a monitoring service. You can choose different protocols and methods of monitoring. One of the most common ones is TCP Monitoring.

Why should you monitor your server?

The main reason why you should monitor your server is to be sure that it is online. 

It is not uncommon to have different problems like incorrect settings, DDoS attacks, hardware malfunction, and more, and experience downtime (offline time). Unfortunately, if you don’t have an active monitoring system, you won’t get any notification when downtime happens.

During the downtime, your clients won’t be able to use your site, application, or service, which can lead to losses and a damaged reputation.

What is TCP Monitoring?

TCP Monitoring, a.k.a. TCP/IP Monitoring, is a process of checking a device (server or network equipment) by establishing a TCP connection (using the TCP protocol) and gathering statistics about latency and packet loss.

The main reasons to have TCP Monitoring are to surveillance your network or devices for communication problems, find the problems early, and get notified on time. 

Depending on the TCP Monitoring Software, there will be various notification methods. For example, it could send constant notifications to a device or schedule reports after a particular amount of time.

A TCP Monitoring can be used for multiple devices too. You can use it to check all of the connected devices on your network. Imagine if you have a big office with 500+ computers. By using such a monitor, you can see if the connectivity is alright and if you need to fix a problem.

A professional TCP Monitoring on your server can:

Discover incoming connections. It will find new connections, and it can analyze the relationship between the processes and applications. That way, you can understand why a particular application is slow.

View the health status of network hardware. You can see all the available network hardware and its status in one place. You can see if there is a problematic device or if everything is in order. That will help you to pinpoint problems right when they arise. You can later resolve the issue with the gathered information without wasting time troubleshooting.

Determine the communication route. A TCP Monitor can map the network and show you the route each TCP query takes. That way, you can find out if the communication is established through the most efficient channel or not. Then, you can use the information and re-route the network devices to get better performance.


Now you know why a TCP Monitor is so important. It takes little to no resources, but it can help you detect a problem right from the beginning. Thanks to it, you can find out where the problem is and start fixing it as fast as possible. Such a monitor will help you have better uptime.
