Internet performance monitoring method and tool Dragon Technology 01-6-6 15:20:25
"You cannot management" "You can not manage what you can't measure), the first principle of management tells us:" Effective management is active for effective monitoring. " This management thought was played in GE and Microsoft, and the principle of six Siki Code was the best embodiment of this idea. Today, with the high-speed development of the Internet and the great importance of network applications, there are more and more management time they spend on them. Therefore, there have been various management tools and service methods, which greatly promotes the rapid development of the Internet performance monitoring. Market status and prospects are foreign countries, and Internet performance monitoring this industry has been very developed, and there are many well-known companies that are engaged in Internet performance monitoring, such as CA, Mercury Interactive, Keynote, BMC, Freshwater, etc. These companies' stocks are excellent in Nasdaq, which are favored by investors, and their market values are around $ 5 billion in the medium-sized enterprises like Mercury Interactive. Internet performance monitoring this industry is refining, from the TCP / IP architecture, from the interface layer to the application layer, there are different products for each layer of different protocols; from the web application, from the public network to the server to the server The background database has a monitoring tool for each part; from functional, there is a monitoring means for network security, speed, usability. This market has developed in developed countries with a relatively perfect network infrastructure and relatively mature e-commerce environment. In the global IT market, the total market for products and services on Internet performance monitoring has reached 20 billion US dollars. In my country, due to network bandwidth, the Internet is popular, online trading environment, etc., Internet performance monitoring this industry is relatively late. However, as the current government supports the strong support of the network economy and the continuous improvement of the hardware and software environment, this market has begun to show. The development of multinational companies in China, the development of online transactions in the financial securities industry, the traditional enterprise's touch network and some e-commerce companies have made a preliminary customer base for the development of their competitiveness. Therefore, the third-party Internet performance monitoring service provides merchant travel technology to life, and has obtained a good market reaction. In the next few years, with the popularity of my country's all-in-Internet and the increasingly mature e-commerce trading environment and the increasingly fierce network competition, the market space will be greatly expanded. At that time, I believe that a large number of companies like the present, Sina has a high-visibility, high-growth company. Common Methods and Tools The operating system of the Internet Server includes several major classes, including UNIX, NT, Linux, facing a complicated network condition and a wide variety of measurement tools, it is difficult to say which tool is more suitable for our practical applications; Its technical implementation and function applications can be roughly divided into the following: 1. Common network monitoring tools, Traceroute, bandwidth measuring tools, traffic monitoring tools, statistical analysis tools, etc. Ping is the simplest network test and diagnostic tool, mainly used to test whether the host can reach, network delay, and packet loss rate. Traceroute is mainly used to measure routing information on the upper end of the network. As the Internet multi-gateway interconnects, it is the purpose of tracking each routing line that may pass through. The measurement of bandwidth is mainly based on the algorithm of a congestion avoidance mechanism in the user mode diagnostic tool, representing the software has Treno et al. Tools for traffic monitoring include online real-time monitoring and offline analysis, such as etherman et al. With the complexity of the internet network structure, in order to fully measure network operation, you need to make more detailed, more accurate measurements for network state, and the SNMP protocol has provided strong support for Internet measurement, and MRTG is a typical statistics based on SNMP. analyzing tool. Second, the commonly used monitoring method According to the installation and measurement method of monitoring software, the Internet monitoring method can be divided into two major categories based on server-side monitoring and user-based monitoring.
1. Based on the server-side monitoring, most monitoring software is based on server-side, ie, after users buy the software, install it on the local server, monitor the operating performance of software and hardware such as locals, databases. The benefit of this monitoring software is that users can understand the efficiency of their local machines, and you can understand the local network connection and some e-commerce processes in the local implementation. But the disadvantage is that it is not possible to directly reflect the actual experience of the end user login website and the e-commerce service provided by the website. Currently, there are many companies in this type of software, like Freshwater, BMC, CA, etc. Freshwater developed Sitescope is a typical server-based network monitoring software. This monitoring software is based on Java technology development, mainly for NT and UNIX system platforms. The main monitoring projects include e-commerce processes, file transfer, server ports, CPUs, disk space, memory, etc., which covers most of the network protocols and services. And monitoring, and can provide a visual and detailed report to users. The BMC's SiteAngel 2000 is another typical server-based Web monitoring tool that monitors system performance including online trading processes, customer database, CRM systems, and ERP systems. It is characterized by monitoring and evaluating the actual operating performance of the website from the outside of the firewall, and gives the monitoring result. 2. User-end monitoring with the development of Internet technology and the transformation of operating ideas, there has been a new type of monitoring. This monitoring service is to distribute software on the client, instead of mounting on a network operator's local server. The network performance is monitored and the end user angle is performed from the end user's angle to find the network bottleneck. The principle of using this monitoring service has fundamentally reflects the user-centered business idea, because of the terminal user Still a UNIX operation platform, don't care about the use of Oracle or Microsoft database. The only user is concerned about the surfing experience of the network, that is, log in to a page or completes if an online transaction can be successful, and the time is how long. Currently, companies that provide user-end monitoring services mainly have Dragonflow, Keynote, etc. The following is actions with Dragonflow's DragonWatch as an example to illustrate the working principle of the client monitoring service. The main feature of DragonWatch is that its monitoring software is distributed over the user, and from the user's perspective, it is the only way to understand the performance of the terminal user login website. Since the end user is distributed in different geographic locations, the DragonWatch monitoring software is considering the distribution of network users and the use of ISP status from statistical perspectives. DragonWatch monitoring software simulates users in different locations to monitor the network, website performance status, then transfer the monitoring data to a powerful central control platform, analyze and process these data, show the network operator with graphical interface . They can analyze the network performance based on relevant data and diagnostic tools, find the connection failure causes and network bottlenecks. For e-commerce websites, business processes (referring to the process of purchasing a book online, completing a registration or a online auction process) performance is an indicator that they are very concerned, because it is directly related to the website's cash income. Fortunately, DragonWatch can now provide monitoring for business process performance, helping network operators understand whether the business process of the website can be completed, how much is completed, whether the user can endure, if the business process failed, Then you can know which step fails, what is the reason for failure.
At present, DragonWatch monitoring services have been spread through more than 20 major cities in China, from the user end to the website's response speed and business process performance, to make customers accurately understand the actual experience of online users, and do when there is a problem in the network Timely alarm, minimize the risk and loss of the website due to performance failures. DragonWatch can monitor the performance of ISP, Cache and mirroring effects, can also monitor bandwidth, gateway, route, etc., through analysis of network delay and response time and business process, the network fault problem can be positioned, diagnostic problem is It happened to occur on the website or on the network. With the popularity of multimedia services and the rapid development of e-commerce, Internet performance monitoring tools will become more abundant, and these tools have become an important cornerstone of network system operation, management, maintenance and planning. These Internet Performance Monitoring Tools The evolution and development of modern network architecture is not open. On the basis of existing network monitoring technology, through the research on Internet monitoring methods and software tools, it will eventually emerge. Rich products.
