实验十九 网络监视器、性能监视器（Experiment 19 network monitor, performance monitor） Experiment 19 network monitor, performance monitor experiment 19 network monitor, performance monitor return [experimental purpose] 1) application of event viewer and performance monitor. 2) master the installation and usage of Network monitor Network monitor. 3) understand the packaging relationship of each layer of data in the network hierarchy. 4) capture the data packets of the ping command related protocol and analyze the structure. [experimental environment] IIS Windows 2000 Server computer, LAN, Windows 2000 Server installation CD. [key points and difficulties] Key points: grasp the method of network monitor, deeply understand the packaging relation of each layer data in network hierarchy, and learn to analyze the structure of common data packets. [experimental content] Monitoring events Web sites in IIS are implemented by IIS services, such as Web sites that rely on the WWW service, and events such as failed service launches tend to imply that the site is not working properly. In addition, such events as TCP/IP errors, and network hardware devices, are often the main culprit for servers that are not working properly. When a system prompts an error or an IIS occurrence of an exception, an experienced administrator usually checks the events recorded by the event viewer. Click [start], [program], [management tool], [event viewer] open the event viewer like the one shown on the right. All events are saved in three event logs: application log, security log, and system log, The types of events that are included are as follows: For the IIS server, the events recorded in the system log are more important. As shown in the figure, select the system log in the event viewer control tree, and the right pane lists all the events that have been recorded, and the events are divided into: errors, warnings, information, and so on. The list to display only the relevant events took place, origin, classificatio
