Cacti is a set of graphical analysis tools for network traffic monitoring based on PHP, MySQL, SNMP and RRDtool. If you want to use CACTI to monitor the Linux server's network card traffic, you need to install Net-snmp-utils-related packages on the monitored

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

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

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

I. Introduction of NethogsShare a check on the bandwidth usage of the detection system process under Linux. Open source tools from GitHub.It does not rely on modules in the kernel. When our server network is abnormal, you can run the Nethogs program to detect that the program is taking up a lot of bandwidth. Find time saved.Second, installation method1. You can install the Yum directly in the Epel sourceYum

First, introduce Linux under the nload is a very useful tool, the function is very strong, but relatively single, can only view the total flow. Can monitor the traffic of the network card in real time, divide incoming,outgoing two parts, namely flow of inflow and outflow At the same time statistics current, average, smallest, largest, total flow value official
