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 all use the while true "dead loop", every 10

Under Windows we can use the ipconfig command to obtain information about the network card, under Linux command is ifconfig We can obtain more information, including the network card to receive and send traffic, in the C language to achieve this command is not a simple matter, thus, the blogger through the access to relevant information, learned that the

In the rapid development of the network era, the use of network traffic is a lot of system users are very concerned about a problem, especially the use of wireless networks, how to view the use of this traffic system, in the Windows 8 system due to the introduction of a new style, many users of the operation is somewha

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 = $ ($ rx1/1000 )) Rx2 = $ (ifconfig eth0 |

When developing network applications, it's always necessary to capture network traffic. windows CE has built-in sniffer tool, netlog for this purpose. it captures network traffics to a file that can be examined with Wireshark or network monitor. To enable it, we need to sele

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 traffic. the exported file is obtaine

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 the average

1. Get Network card informationunder Windows Enter cmd, enter " typeperf-qx | find "Network Interface" | find "Bytes" > C:\network.txt"Then it will be under the C drive.generate Network.txt files, open files in which you can search for network interface performance-related parameters, and use these performance counter paths to get related performance values.
