This spring Facebook and its products Instagram and WhatsApp suffered a serious downtime accident. Facebook users around the world responded that they had encountered problems with Facebook, Instagram and WhatsApp, and could not post. Subsequently, engineers from a foreign network security management company thought that the downtime might be caused by a BGP routing error, which led to a brief abnormality in the service of visiting some well-known Internet Co. However, cloud Monitor Company ThousandEyes believes that this is caused by internal errors, because Facebook returns the "500 internal server error code". Facebook then issued a message that the service interruption was not related to DDoS, which was caused by the change of server configuration.
Although the problem of server system failure has been solved quickly, the downtime accident has aroused widespread concern. The following is an understanding of Microsoft's operating system resource monitor. The resource monitor is a system application already installed in Microsoft Windows Server 2008 R2 operating system. It can display the usage of hardware (CPU, memory, disk and network) and software (file handle and module) in real time. The resource monitor comes in the operating system of Windows Vista and later (in Windows Vista, it is part of the reliability and performance monitor). The user can execute resmon.exe to start the program (only perfmon.exe in Windows Vista). The resource monitor has made great use of the Windows event tracking (ETW) mechanism introduced by Windows 7, and the counter setup (event tracking session) has also been used by the resource monitor to provide logs.
The R2 in the Windows Server 2008 R2 operating system is called Release 2, that is, the second release version, which is an improved version of the first version of the 2008 system. Windows Server 2008 R2 continues to enhance the application of virtualization, system management flexibility, network access mode, information security and other fields, and strengthens PowerShell's management instructions for each server role.
Next, share the steps and methods of how Windows Server 2008 R2 can view the use of computers through resource monitors for small partners.
The first step is to start the Windows Server 2008 R2 operating system, as shown in the figure. Click the start button of the taskbar to start the menu.
The second step, as shown in the diagram, is to enter task manager in search box. Displays the closest match and clicks "use task manager to view the run process" icon.
The third step is to evocate the "Windows task manager" program window, as shown in the figure. Select the "performance" tab, and the next step will be to view the operation of the computer through the resource monitor.
The fourth step, as shown in the figure, is to evocate the "performance" option interface. Click the "resource monitor..." button below to open the resource monitor dialog box.
The fifth step is to display the resource monitor dialog box, as shown in the figure. Select the "Overview" tab and click the down arrow on the right side of CPU, disk, network and memory, respectively.
The sixth step, as shown in the diagram, is to complete the operation of using the resource monitor to see the use of the computer. The end of this case, I hope we can help.
