Which CVM traffic monitoring software is better? It is very important to know how much network bandwidth is consumed, how much traffic is consumed by each process on the CVM, and the activity of opening ports to the outside world. Without dedicated tools, it is not easy to get data. Let's share a few practical monitoring tools in our daily work.

1. Iftop

Iftop is a linux command line program that graphically displays the bandwidth used by network connections in real time. Just like top, iftop updates dynamically every few seconds. Iftop shows the bandwidth of uploads and downloads used by network connections, which is a necessary command tool for operators.

Yum install iftop

two。 Enter iftop directly under the command line to run the program using the

II. Dstat

Dstat is a comprehensive server performance view command. Dstat allows you to view all the resources of the system in real time, for example, or directly compare the number of network bandwidth with disk throughput (at the same time interval).

Installation

Yum install dstat-y

Use

[root@localhost ~] # dstat-cdnrsy

III. Nload

If you want to monitor network throughput in the command line interface, just choose nload! It is a console application that monitors network traffic and bandwidth usage in real time. It separates inbound and outbound traffic and lets users know clearly inbound and outbound traffic.

Installation

Yum install nload-y

Use

Nload-u M

Parameter description
