​Get familiar with TCP monitoring

Being online is not something to be taken for granted. Different factors can make your business fall. You have to permanently check the condition of your complete infrastructure to avoid interruptions. TCP monitoring can give you a hand!

Definition of TCP monitoring

TCP (Transmission Control Protocol) monitoring is a procedure to check network equipment, like a server, by establishing a TCP connection and collecting statistics about packet loss and latency. There are different monitoring methods based on the use of protocols. However, the use of TCP protocol is one of the most common. The reason is the Transmission Control Protocol (TCP) allows an effective detection of communication issues on network devices. Additionally, TCP monitoring can check multiple devices on large networks.

Why do you have to monitor the server?

You have to monitor the server because it is vital for your business to keep operating online. Your business could be offline due to an issue on your server, but if you don’t realize that, you won’t fix it quickly. That can cause money loss and disappoint clients.

Monitoring your server allows you to detect if something is wrong and to identify the cause. You need this information to fix the problem. Downtime can happen due to different causes. If you are a network administrator, you know about common issues. Human errors while defining settings, hardware or software failures, cyber-attacks, you name it!

A good solution for you to be constantly notified about the server’s status is to have Transmission Control Protocol monitoring working on your side.

TCP monitoring abilities

  1. Checking of transaction delays.

If processing a specific data packet takes longer than expected, TCP monitoring will detect it and notify you.

  1. Monitoring network hardware status.

TCP monitoring can check the status of multiple machines on a network. It will monitor the connectivity and confirm that everything is working ok or detect issues on a specific machine malfunctioning to notify you.

  1. Identifying communication routes.

TCP monitoring can map the network and point out the route TCP queries take. Each of them! So you can evaluate if the communication is getting established through the most efficient channels or if there is room for improvement there. With this information, you can easily boost a much better performance by rerouting network devices.

  1. Finding incoming connections.

It can find them and monitor the processes of applications to detect issues like sluggishness.

  1. Monitoring the CICSplex.

It can track the work across the CICSplex, which is a cluster for enabling multiple CICS (Customer Information Control System) regions to communicate between them and collaborate in handling inbound work requests.

  1. Getting performance data.

This is very important. While monitoring, TCP can collect data that you can use not only to detect and fix current issues but also to plan ahead. You can scale your capacity and improve efficiency and performance before having problems.
