splunk monitor network traffic

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

An intuitive network bandwidth metering device with both digital and graphical display.2. Let you clearly see the data transmission during browsing and uploading and downloading.

Using Iptraf in Linux for network traffic analysis Iptraf is an excellent free software that monitors network traffic in linux, especially installed on the firewall, and works with Iptables, the network that monitors the flow through the firewall is abnormal, and the effect

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

Compared with nload, Iptraf is an excellent free small software that monitors network traffic of specific ports in linux.System Environment: centos6.3Iptraf: iptraf-3.0.0 2. view the dependency package: # rpm-qa | grep gcc # rpm-qa | grep glibc # rpm-qa | grep ncurses if not, please install the corresponding development kit (centos default installation source) # yum installgccglibcncurses III. Installation

Iftop is mainly used to show the local network traffic and the flow of communication between each other, such as the size of the flow between the individual and that machine, is very suitable for proxy server and iptables server use to view network status can use Netstat, nmap and other tools. To view real-time network

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

Can monitor all resource states of the system. Average load, network card traffic, disk status, memory usage, and so on. Unlike other system state monitoring tools, it can print historical information that displays the System state information from 0 o'clock to the current time of the day.

developed to assist in TCP Parameter Optimization, but here we do not want to study the TCP Window Scale and maximum segment length, because this is not the focus of our current discussion. However, when testing a high-throughput AP, you may find it necessary to tune TCP parameters so that you can get a larger throughput on each iPerf client-For details, see DrTCP.
