Including desktop applications, Linux system management, kernel research, embedded systems, open source, and other basic categories. many articles have introduced how to monitor bandwidth in

I suddenly wanted to monitor the network card Traffic in Linux and didn't want to use cacti. I thought it was very troublesome to Configure SNMP. Ready-made tools seem to be useless. Decide to write a script by yourself. Click (Here) Fold or open #! /Bin/bash Rx1 = $ (ifconfig $1 | grep "RX bytes" | awk '{print $2}' | awk-F: '{print $2 }') Sleep 1 Rxa

Linux with tcpdump network traffic monitoring, export files get windows with wireshark analysis linux command line: tcpdump-ieth1-s0host10121293-woutputtxt-i specified on eth1 listen, this according to different machines, by default, tcpdump is used in eth0 linux to monitor network

Use iftop to monitor network traffic Iftop is a useful tool. The following command monitors the wireless network card of my notebook Iftop-I wlan0 Basic description: 1. the main part of the screen is the data transfer between two machines, with an arrow indicating the direction. The three values on the right are

In linux, tcpdump is used to monitor network traffic, and exported files are obtained to wireshark in windows to analyze the command lines in linux: tcpdump-I eth1-s 0 host 10.12.129.3-w output.txt-I indicates listening on eth1.

The server environment is typically used under Centos7,centos iftop, or nethogs for network traffic monitoring.All 2 tools need to install Epel first, because this library usually does not own the operating System.Then install Epel first, using the following commands:RPM-UVH https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpmAfter the Epel installation is successful, we can install Iftop

Iftop is a useful tool. The following command monitors the wireless network card of my notebookIftop-I wlan0For example, if I play a video of letv, The iftop displays the following information:Basic description:1. the main part of the screen is the data transfer between two machines, with an arrow indicating the direction. The three values on the right are the average traffic of the past 2 seconds, 10 secon

Nload is a simple and easy-to-use bandwidth flow monitoring tool under Linux, and dynamic graphics based on character interface display the current traffic of the NIC. However, CentOS official source does not have it, can not directly use Yum installation. We can download the third party RPM release platform and recommend the following source, which releases multiple RPM packages http://pkgs.repoforge.org/nload/ Installation method: 1. Find the ap

I looked at the/proc/net/dev under Linux to record the number of packets and bytes sent and received by each network card. So initiation thought, wrote one.
