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

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 default value is eth0,This is not specified at the beginning, and the traffic of a cert

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

This article introduces how to use Python to view network traffic information of the system. if you need it, you can refer to it for reference. Let's take a look. Preface The traffic information can be directly stored in/proc/net/devTo view, the program implemented by the author uses the command:

Sometimes we need a more real-time view of the network card traffic on the server, here I wrote two small script, one with the shell (first, only one network card can be viewed at a time), another in Python (after writing, can view more than one network card). In the script
