Use python to create a network card Traffic chart !!! Project Background: Using python to implement an automated network card Traffic chart, which gives us a deeper understanding of how to implement an automated O M platform, It will also help us to implement some of the existing monitoring software. Implementation environment: Virtual Machine VMwareWorkstation12 player

Article title: use Mrtg to monitor network traffic (for Linux ). 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. 　　 Although mrtg has been used to monitor the traffic of network devices, I still want to write an article about this. Mrtg is a powerful software, in additio

Determine the mode of the network type and the type of virtual Connect network design (active/standby vs active/active)When faced with choosing which virtual Connect network design type (active/active (a/a)Vs. Active/standby (A/S) uplinks), you need to consider the types of enclosure internal needs to support network traffic, for exampleFor example, if there is more server-to-

IP address on the Router.If your Linux machine has installed Perl, you can also copy the Movie Maker to Linux, use Linux for configuration files, and then copy the configuration files back to Windows. Otherwise, the third method is to manually create a configuration file. The MRTG kit provided by the municipal network center contains the mrtg. cfg sample configuration file that has been modified by me. Let's take this file as an example to understand the significance of the configuration file p

First, verify that the server hardware is sufficient to support the current traffic. Ordinary P4 servers generally support up to 100,000 independent IPs per day, if the traffic is larger than this, Then you must first configure a higher-performance dedicated server to solve the problem , otherwise optimization will not

In addition to the panel provided by the service provider, we can also install vnStat to monitor the upstream and downstream traffic of your VPS or server on a daily basis. the vnStat installation method is simple, which can be divided into compilation and installation or direct installation through the source. 1. Compile and install this method for all Linux releases. first, download vnStat: wgethttp: // h

Use Qt to develop a traffic graph for multiple devices (with a project diagram ), I. Description: In actual projects, we mainly use Qt to develop CS programs, of course, mainly clients. In the company project, this requirement is to display the traffic curves of multiple devices in real time. The devices send the traffic information to the

Writing this article, not only for the sake of backwardness, mainly expresses to those who cheat the traffic seller's hatred! It's been 5 years since the website was built, from the previous free space station to the current server to do, everything is built around the site in the work, all work, the most important thing is the flow of this problem, now the industry is fierce competition, there is a new ide

This article mainly introduces how to use PHP to solve the problem of large traffic and high concurrency, has a certain reference value, and now share to everyone, the need for friends can refer to Ordinary P4 server can generally support up to 100,000 independent IPs per day, if the traffic is larger than this, then you must first configure a higher performance

blocked. The system software can be Windows2000, WindowsNT, or Windows XP. Wireless Network advantages 1. It not only saves IP resources, but also uses the Cache Technology on the Proxy server, so that resources accessed by computers on each campus network are stored on the hard disk of the Proxy server, in the future, machines can access the same resources directly from the Proxy

(mostly using iptables to do the tagging) function.Currently, the TC can be used by the filter has: Fwmark classifier, u32 classifier, based on the routing of the Classifier and RSVP classifier (for IPV6, IPV4), etc., wherein the fwmark classifier allows us to use the Linux netfilter code to select the traffic, The U32 classifier allows us to select the traffic based on any header. It should be noted that
