1 Server Manager Diagnostics Page 653. Information. Audit Success. Audit Failure The view shows the total number of events in the last hour, 24 hours, 7 days, and the total. Each of these nodes can be expanded to show the counts of particular event IDs within each level. Double-clicking on the event ID count shows a detailed list of the events with the matching event ID. This is very useful for drilling on the specific events to see when they are occurring. The Overview and Summary page also has a Log Summary section, which shows a list of all the various logs on the server. This is important, as there are now over 100 different logs in Windows Server 08 R2. In addition to the standard system, security, and application logs, there is a setup log and a forwarded events log. Then there are the numerous application and services logs, which include logs for each application, service, and a huge number of diagnostic and debugging logs. For each of the logs, the Log Summary section shows the log name, current size, maximum size, last modification, if it is enabled, and what the retention policy for the log is. This allows the administrator to quickly see the status of all the logs, which would be a daunting task otherwise. Of course, the logs can be viewed directly by expanding the Windows Logs folder or the Applications and Services Logs folder. The Windows Logs folder contains all the standard application, security, setup, system, and forwarded events logs. The applications and services logs contain all the other ones. Custom views can be created to filter events and combine logs into a coherent view. There is a default Administrative Events view, which combines the critical, error, and warning events from all the administrative logs. There is also a custom view created for each role that is installed on the server. New ones can be created by the administrator as needed. Subscriptions can collect events from remote computers and store them in the forwarded events log. The events to be collected are specified in the subscription. The functionality depends on the Windows Remote Management (WinRM) and the Windows Event Collector (Wecsvc) services, and they must be running on both the collecting and forwarding servers. Server Manager Performance Monitor The Performance monitor is incorporated into Server Manager as well. This diagnostic tool enables the administrator to monitor the performance of the server in real time, generate reports, and also save the performance data to logs for analysis. The top-level folder of the Performance Monitor displays the System Summary. This gives a comprehensive overview of the memory, network interface, physical disk, and processor utilization during the past 60 seconds (shown in Figure.6). The System Summary is organized in a matrix, with a column for each instance of the network interface, disk, and processor. The information is updated every second. Unfortunately, the pane is a fixed height, so it is hard to see all the information at once, and excessive scrolling is needed.

2 654 CHAPTER Windows Server 08 R2 Management and Maintenance Practices FIGURE.6 System Summary in Performance Monitor. The Monitoring Tools contains the Performance Monitor tool. This tool allows you to monitor the performance of the server in more detail. The Performance Monitor has not really changed from previous versions of Windows. It allows you to select performance counters and add them to a graph view for real-time monitoring. The graph can be configured to be a line graph, a bar graph, or even a simple text report of the counters being monitored. The monitor shows the last, average, minimum, maximum, and duration of the windows (1 minute 40 seconds by default). For longer-term tracking, the Data Collector Sets can be used. Data Collector Sets can log data from the following data sources:. Performance counters. Event traces. Registry key values This data can be logged over an extended period of time and then reviewed. The data collected will also be analyzed and presented in reports that are very useful. There are two reports defined by default, the System Diagnostics and System Performance. When roles are added, such as the Active Directory Domain Services role, there might be additional Data Collector Sets defined. These data sets gather data that is presented in reports, which is new to Windows Server 08 R2. There is a new reports folder in the Performance Monitor where the reports are saved. To generate data for a Performance Monitor report, execute the following steps:

3 Server Manager Diagnostics Page Launch Server Manager. 2. Expand the Diagnostics node. 3. Expand the Performance node. 4. Expand the Data Collector Sets node. 5. Expand the System node and select the System Performance Data Collector Set. Note that the Data Collector Set includes an NT Kernel trace and performance counters. 6. Right-click on the NT Kernel trace object and select Properties. Note the events that will be collected. Click Cancel to exit without saving. 7. Right-click on the Performance Counter object and select Properties. Note the performance counters that will be collected. Click Cancel to exit without saving. 8. Right-click on the System Performance Data Collector Set and select Start. The Data Collector Set will start collecting data. 9. Right-click on the System Performance Data Collector Set and select Latest Report. The report will show a detailed analysis of the system performance. The Summary and the Diagnostic Results are shown in Figure.7. The Diagnostic Results indicate that memory is the busy component on the DC1 server. The report contains a wealth of details on the CPU, Network, Disk, Memory, and overall report statistics. FIGURE.7 System Performance Report in Performance Monitor Data Collector Sets. You can also view the performance data that the report is based on directly. This can be done by right-clicking the specific report and selecting View, Performance Monitor. This shows the graph of all the counters selected during the data collection. You can select which counters to show in the graph.

4 656 CHAPTER Windows Server 08 R2 Management and Maintenance Practices The System Performance Data Collector Set only collects for 1 minute, which is not long enough for detailed trend analysis. New Data Collector Sets can be defined in the User Defined folder. For example, to create a duplicate of the System Performance Data Collector Set that will run for an hour instead of a minute, do the following: 1. Launch Server Manager. 2. Expand the Diagnostics node. 3. Expand the Performance node. 4. Expand the Data Collector Sets node. 5. Select the User Defined node. 6. Right-click on the User Defined node and select New, Data Collector Set. 7. Enter System Performance 1 Hour for the name and make sure that the Create from a Template is selected. Click Next. 8. Select System Performance and Click Next. 9. Click Next to keep the default root directory. 10. Select the Open properties for this Data Collector Set and click Finish. 11. Click on the Stop Condition tab. 12. Change the Overall Duration setting to 1 hour. 13. Click OK to save. This Data Collector Set can now be run and will collect the same data as the default System Performance, but for 1 hour instead of just 1 minute. Device Manager The Device Manager node shows the hardware that is installed on the server. It shows the hardware grouped by type of device, such as Disk Drives, Display Adapters, and Network Adapters. Each instance of the device type is listed in a node underneath the device type. The Device Manager can be used to update the device drivers of the hardware, to change settings, and to troubleshoot issues with the hardware. Specifically, you can perform the following tasks:. Scan for new hardware. Identify hardware problems. Adjust configurations. View device driver versions. Update the device drivers. Roll back device driver upgrades. Enable or disable hardware For example, sometimes older video drivers or network card drivers will cause problems with the system. It is easy to check the Microsoft online driver repository using Device

Select the network adapter to check. 3. Select Action, Update Driver Software from the menu. 4. Click on Search Automatically for Updated Driver Software. 5. Click on Yes, Always Search Online (Recommended). 6. Install the update if found. 7. Click Close to exit the wizard. NOTE Many times, the latest version of the driver will already be installed. In these cases, the message The best driver for your device is already installed will be shown. Server Manager Configuration Page The Configuration page in Server Manager is somewhat misleading. This is not the page from which you would configure the server. The Configuration node in Server Manager is simply a container for the following four snap-ins:. Task Scheduler. Windows Firewall with Advanced Security. Services. WMI Control These snap-ins enable the administrator to control some elements of the server configuration and are covered in the next four sections. Task Scheduler One of the greatly expanded features of Windows Server 08 R2 is the Task Scheduler. In previous versions of Windows, this was an anemic service with limited options and auditing features. The Task Scheduler features in Windows Server 08 R2 have been expanded into a more sophisticated tool. The scheduler can start based on a variety of triggers, can take a number of predefined actions, and can even be mitigated by conditions and the settings. Appropriately, there are expanded elements to the Task Scheduler, as follows:. Triggers Tasks run when the trigger criteria are met. This could be a scheduled time, logon, startup, idle, log event, user session connect or disconnect, or workstation lock or unlock. These various triggers give the administrator a wide range of options on when to start a task.
