Ntopng Introduction:Ntopng is the original ntop next-generation version for real-time network traffic monitoring display. Ntopng is similar to the RMON Remote network Monitoring agent, with built-in Web service capabilities that use the Redis key value service to store statistics on a time series basis. You can install Ntopng on any designated monitoring server, and you can access the

How to crawl HTTP traffic packets under Linux (Httpry)September 5, 2014 North For some reason you need to sniff HTTP web traffic (that is, HTTP requests and responses). For example, you might test the performance of a Web server, or X-Uy debug a Web application or restful service, or try to resolve a PAC (Proxy auto-configuration) problem, or check for any malici
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 solve the performance problem completely.Second

When the access volume of some applications increases, the performance of the entire server cluster can be improved by adding server nodes, which also benefits applications.

I. Introduction
1. ntopng is the next-generation ntop version. It monitors and displays network traffic in real time. Ntop is based on Libpcap and it is written in a portable way to run on UNIX platforms. MacOSX is the same as Win32.

it has been a great success.In order to make scratch with the Gpio interface of the Raspberry Pi, the first thing you have to do is to open the program, enter the editing interface, choose to start the Gpio server. Then you can use the broadcast block to identify the Gpio interface you want to use. In the above, these two broadcast blocks point to Config19out and Gpio19on respectively. And the Gpio 19 is pointing to the red LED light.For more informa

Background knowledgeOften for large data center networks (Networks, or DCN), each server is used very differently, and the average usage is almost nonexistent, and most of the situation is that 70% of usage and traffic requirements are concentrated on a small subset of servers, This is also the problem of building a cloud computing hub through a LAN network.Is the hotspot used by data center servers in most
False flow refers to those in order to cheat advertising costs generated by artificial operation of the flow, (artificial operation may be to click on your ads, visit the landingpage, or to complete a simple task.) The specific situation also depends on different forms of advertising to judge. This type of traffic usually does not produce any transformational behavior on the site.
