Linux VPS traffic monitoring – iftop installation tutorial and detailed usage explanation

In the top command in the previous article, we can see similar VPS traffic monitoring return data. By the way, we will share an iftop traffic monitoring tool similar to the top command. It cannot be run directly before using the iftop command. We need to install it before it can be used.

If we need to install the official installation package, we need to download it from the official website wget. Official address: http://www.ex-parrot.com/~pdw/iftop/ Of course, there is no need to be so complicated. Use the command to install directly in our centos or debian system.

CentOS system runs: yum install iftop Debian system runs: apt-get install iftop

During the installation process, we need to enter y to continue the steps, and we will be reminded during the installation process. After the installation is complete, we can use the iftop command to activate monitoring.

Detailed explanation of iftop command parameters:

TX: represents the sent traffic; RX: represents the received traffic; TOTAL: represents the total traffic; PEAK: represents the peak traffic data; RATES: represents the average traffic of 2, 10, and 40 seconds.
