debian monitor network traffic

Network traffic monitoring tools have a lot of, such as: MRTG, Cacti, Zabbix and so on, they have their own characteristics, different focus, only for different application scenarios for a variety of special needs. In addition to network traffic monitoring tools, there are nagios such a monitoring host State tools, not

Click Monitoring to monitor the client's real-time network traffic, and you can see that the maximum download bandwidth for the client "192.168.

In a class Linux system, you can use top to view information such as system resources, processes, memory consumption, and so on. View network status You can use Netstat, nmap and other tools. To see real-time network traffic, monitor TCP/IP connectivity, and so on, you can use Iftop.First, Iftop What is it? The iftop i

large number of data files to the server, and then use the SAR command to view the network card traffic, found that the sending traffic instantaneous in 120,000 kb/s, converted to B/s basically in 940-950mb/s, means that gigabit network card traffic is basically full , the

Nload is a real-time network traffic monitoring software in Linux. Because I often want to monitor traffic monitoring in Linux, I chose it. Ubuntu installation is very simple. You can install it through sudo apt-get install nload. Input nload directly under shell, and press enter to view the following picture. Instal

, the network adapter will accept all incoming data, whether or not it is sent to itself. --- The Color is displayed on the terminal. of course, only connections via telnet or ssh are allowed. that is, connection via a terminal that does not support Color is certainly not colored. --- Logging generates log files at the same time in the/var/log/Iptraf directory. --- The Activity mode can be set to kbit/sec or kbyte/sec. --- After selecting Source MAC a

Install Nload: # wget http://www.roland-riegel.de/nload/nload-0.7.2.tar.gz# tar zxvf nload-0.7.2.tar.gz # cd nload-0.7.2 #. /configure -- prefix =/usr/local/nload make install. Set the installation directory by yourself. The installation is very simple and basically there will be no errors! Then, it can be used to monitor network card Traffic: #/usr/local/nload/

Article title: use Iptraf in Linux to analyze network traffic. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. Iptraf is an excellent free software for monitoring network traffic in

In the Linux/Unix monitoring system, the real-time traffic of the network card, iftop is a goodIf you select iftop, the source, target, and port are displayed in detail. iftop provides more information than ifstat. However, if you only monitor the network card Traffic, ifsta

data. Therefore, in terms of network management, it is necessary to understand the traffic status of our hosts and limit or increase bandwidth based on traffic.We can download the MRTG software from the http://www.mrtg.org. Go to http://www.stat.ee.ethz.ch/mrtg/to get the output result of the mrtgtraffic monitoring chart.MRTG is written in Perl and uses zlib, Gd, and PNG functions (zlib is used to compress

subnet mask. for example, to represent 192.168.0.0 and a network segment with 256 IP addresses, fill in 192.168.0.0, subnet: 255.255.255.0. Similarly, All is represented by 0.0.0.0, and subnet is also represented by 0.0.0.0. Port: enter the Port number to be filtered in the column. 0 indicates any Port number. The Include/Exclude column must be filled with I or E, I indicates including, and E indicates exclusion. After entering the information, press

Iftop command Installation The code is as follows Copy Code [Root@test iftop-0.9]# make[Root@test iftop-0.9]# make install[Root@test iftop-0.9]# Iftop Instance The default is to monitor the traffic of the first network card Iftop Monitoring eth1 Iftop-i eth1 Direct IP display without DNS reverse resolution Iftop-n Di

, which is automatically changed by default. Note that the capitalization units are different (same as-u).Devices: Custom monitoring of the network card, the default is all monitoring, using the left and right key switch. If only monitor eth0 command: nload eth0 method Two, Iftop tool SOURCE Package Path: Http://www.ex-parrot.com/%7Epdw/iftop/download/iftop-0.17.tar.gz 1, Iftop interface related instruction

There are many open-source network monitoring tools available on the web for Linux operating systems. For example:You can use the command iftop to check bandwidth usage, netstat to view interface statistics reports, and other tools BANDWIDTHD, speedometer, nethogs, Darkstat, Jnettop, Ifstat, Iptraf, Nload and ntop and so on.But these tools are statistical card access data, if you want to find a like 360 security guard on Windows, can be in real-time s
