Performance and Reliability Monitoring Getting Started Guide for Windows Server 2008

Applies To: Windows Server 2008

Windows Server® 2008 includes Windows Reliability and Performance Monitor, which is a Microsoft Management Console (MMC) snap-in that combines the functionality of previous stand-alone tools including Performance Logs and Alerts, Server Performance Advisor, and System Monitor. It provides a graphical interface for customizing Data Collector Sets and Event Trace Sessions.

It also includes Reliability Monitor, an MMC snap-in that tracks changes to the system and compares them to changes in system stability, providing a graphical view of their relationship.

What is performance and reliability monitoring?

In general terms, performance is the measure of how quickly a computer completes application and system tasks. Overall system performance might be limited by the access speed of the physical hard disks, the amount of memory available to all running processes, the top speed of the processor, or the maximum throughput of the network interfaces.

After identifying hardware performance limitations, IT professionals can monitor individual applications and processes to assess how much of the available resources they use. IT professionals can use a comprehensive analysis of performance of both application impact and overall capacity to help plan for deployment and grow system capacity with increasing demands.

Windows Reliability and Performance Monitor enables you to track the performance impact of applications and services, and to generate alerts or take action when user-defined thresholds for optimum performance are exceeded.

The reliability of a system is the measure of how often the system operates as it is configured and expected to perform. Reliability can be reduced when applications stop responding, services stop and restart, drivers fail to initialize, or in the worst case, when operating systems fail.

Reliability Monitor provides you with a quick, visual view of the average stability of your system. In addition, it tracks events that will help you identify what causes reductions in reliability. By recording not only failures (including memory, hard disk, application, and operating system failures), but also key events regarding the configuration of your system (including the installation of new applications and operating system updates), you can see a timeline of changes in both the system and reliability, and can identify how to get your system back to optimal reliability when it does not behave as expected.

What's new in performance and reliability monitoring?

Key new features for monitoring performance and reliability in Windows Server 2008 include the following.

Data Collector Sets

An important new feature in Windows Reliability and Performance Monitor is the Data Collector Set, which groups data collectors into reusable elements for use with different performance monitoring scenarios. Once a group of data collectors is stored as a Data Collector Set, operations such as scheduling can be applied to the entire set through a single property change. You can schedule repeated collection of a Data Collector Set to create logs, load it in Performance Monitor to see the data in real time, and save it as a template to use on other computers.

Windows Reliability and Performance Monitor also includes default Data Collector Set templates to help you begin collecting performance data immediately.

Wizards and templates for creating logs

You can now add counters to log files and schedule their start, stop, and duration through a wizard interface. In addition, if you save this configuration as a template, you can collect the same log on subsequent computers without repeating the data collector selection and scheduling processes. Performance Logs and Alerts features have been incorporated into the Windows Reliability and Performance Monitor for use with any Data Collector Set.

Resource View

The new Resource View screen provides a real-time graphical overview of CPU, disk, network, and memory usage. By expanding each of these monitored elements, you can identify which processes are using which resources. In previous versions of Windows, this real-time, process-specific data was only available in limited form in Task Manager.

Reliability Monitor

Reliability Monitor calculates a System Stability Index that reflects whether unexpected problems reduced the reliability of the system. A graph of the Stability Index over time quickly identifies dates when problems began to occur. The accompanying System Stability Report provides details to help troubleshoot the root cause of reduced reliability. By viewing changes to the system (installation or removal of applications and updates to the operating system) side by side with failures (application, operating system, or hardware failures), you can develop a strategy for addressing the issues quickly.

Unified property configuration for all data collection, including scheduling

Whether you create a Data Collector Set for one-time use or to log activity on an ongoing basis, the interface for creation, scheduling, and modification is the same. If a Data Collector Set proves to be useful for future performance monitoring, you do not need to recreate it. You can reconfigure or copy it as a template.

User-friendly diagnosis reports

Users of Server Performance Advisor in Windows Server 2003 can now find the same kinds of diagnosis reports in Windows Reliability and Performance Monitor in Windows Server 2008. You can generate reports more quickly and can generate reports from data collected using any Data Collector Set. This allows you to repeat reports and assess how recommended changes have affected performance or modified the report recommendations. Windows Reliability and Performance Monitor also includes preconfigured performance and diagnosis reports for quick analysis and troubleshooting.

Who should use Windows Reliability and Performance Monitor

This guide is intended for the following audiences:

  • IT planners and analysts who are evaluating the product.

  • Enterprise IT planners and designers.

  • Early product adopters.

Benefits of Windows Reliability and Performance Monitor

The most significant advantage of Windows Reliability and Performance Monitor over previous individual tools like System Monitor, Performance Logs and Alerts, and Server Performance Advisor is that it combines the functionality of those tools into a single interface with common methods for defining the data to be collected. The Data Collector Set makes a group of counters portable.

Resource View in Windows Reliability and Performance Monitor provides a much more in-depth view of system activity and resource usage than previous tools like Task Manager. The ability to view resource usage by process helps you identify problem applications quickly, isolate and shut down resource-intensive processes, and plan for the distribution of server roles and applications across multiple servers as infrastructure grows.

Reliability Monitor helps you to quickly diagnose potential causes of instability so that you can apply rollback scenarios or updates in a targeted manner, rather than attempting a broad-spectrum update or reconfiguration in response to sudden changes in system behavior.

In this guide

  • The following are key scenarios for monitoring performance and reliability:

    • Scenario 1: Monitoring general system activity using Resource View

    • Scenario 2: Monitoring specific system activity using Performance Monitor

Highlight the counter group or expand the group and highlight the counter you want to add, type the process name in the drop-down below the Instances of selected object box, and click Search. The process name that you type will be available in the drop-down list to repeat the search with other counters.

If no results are returned and you want to clear your search, you must highlight another group. If there are not multiple instances of a counter group or counter, the search function will not be available.

Add only certain instances of a counter

Highlight a counter group or counter in the list, select the process you want from the list that appears in the Instances of selected object box, and click Add.

Multiple processes can create the same counter, but choosing an instance will collect only those counters produced by the selected process.

Note

Unless you select a specific instance, all instances of a counter are collected.

Once you have added counters to the Performance Monitor display, you can change the view to help you identify information that you are looking for.

To monitor current system activity from selected counters in Performance Monitor

  • The default display for Performance Monitor is the Line graph. In this display, two minutes of data appear in a rolling format from left to right, labeled along the X axis. This enables you to observe changes in each counter's activity compared with previous behavior over a short period of time. Hover the mouse pointer over a line in the graph to see details for the counter the line represents.

  • Change the display for the current set of data collectors using the drop-down menu on the toolbar. The Histogram bar displays information in real time, allowing you to observe changes in each counter's activity.

  • The Report display shows current values for each selected counter in text format.

  • Below the display, each counter is listed in a legend with the color of the graph line, its Scale, the Counter, the Instance (in this example, all instances are selected), the Parent (not applicable when all instances are selected), the Object, and the Computer.

    • You can select or clear the check box in each row to toggle whether the counter appears in the current display without removing the counter from the list.

    • Selecting a row in the legend displays specific information about the counter in the area above the legend.

    • While a row is selected in the legend, click the Highlight button on the toolbar to highlight that counter in the graph. To return to normal display, click the Highlight button again.

    • To change the properties of how the counter is displayed, right-click the row in the legend and select Properties from the context menu. The Performance Monitor Properties page will open on the Data tab. Use the drop-down menus to choose your preferences.

To move through the data in collection time increments, click the Forward button on the toolbar.

  • Freezing the display in the Line graph will change the amount of time included in the X axis when observation is resumed.

Note

When finished with this task, do not close Windows Reliability and Performance Monitor. The data collectors in the Performance Monitor view will be used in the next scenario.

Scenario 3: Create a Data Collector Set from Performance Monitor

Overview: Creating a Data Collector Set from Performance Monitor

Real-time viewing of data collectors is just one way to use Performance Monitor. Once you have created a combination of data collectors that show you useful information about your system in real time, you can save them as a Data Collector Set, which is the building block of performance monitoring and reporting in Windows Reliability and Performance Monitor. It organizes multiple data collection points into a single component that can be used to review or log performance.

In this task, you will create a Data Collector Set from counters that are selected in the real-time Performance Monitor view.

Prerequisites for creating a Data Collector Set from Performance Monitor

To complete this task, ensure that you meet the following requirements:

  • Windows Server 2008 is installed.

  • You are logged on as a member of the local Administrators group, or you are logged on as a member of the Performance Log Users group and have completed the procedure to grant the Log on as a batch job user right to the Performance Log Users group.

  • Windows Reliability and Performance Monitor is running.

  • At least one data collector is selected for display in Performance Monitor.

Known issues for creating a Data Collector Set from Performance Monitor

In order to use the Windows Kernel Trace provider, you must be logged on as a member of the local Administrators group. However, many other data collectors including the ones listed in the previous example are accessible to members of the Performance Log Users group.

Steps for creating a Data Collector Set from Performance Monitor

To create a Data Collector Set from Performance Monitor

  1. Begin with the display of counters from the previous procedure. If you no longer have these settings, start Performance Monitor and add counters to create a custom view you want to save as a Data Collector Set.

  2. Right-click anywhere in the Performance Monitor display pane, point to New, and click Data Collector Set. The Create New Data Collector Set Wizard starts. The Data Collector Set created will contain all of the data collectors selected in the current Performance Monitor view.

  3. Type a name for your Data Collector Set and click Next.

  4. The Root Directory will contain data collected by the Data Collector Set. Change this setting if you want to store your Data Collector Set data in a different location than the default. Browse to and select the directory, or type the directory name.

Note

If you enter the directory name manually, you must not enter a back slash at the end of the directory name.

  1. Click Next to define a user for the Data Collector Set to run as, or click Finish to save the current settings and exit.

  2. After clicking Next,you can configure the Data Collector Set to run as a specific user. Click the Change button to enter the user name and password for a different user than the default listed.

Note

If you are a member of the Performance Log Users group, you must configure Data Collector Sets that you create to run under your own credentials.

  1. Click Finish to return to Windows Reliability and Performance Monitor.

    • To view the properties of the Data Collector Set or make additional changes, select Open properties for this data collector set. You can get more information about the properties of Data Collector Sets by clicking the Help button in the Properties page.

    • To save the Data Collector Set without starting collection, click Save and close.

Scenario 4: Create and schedule logs from a Data Collector Set

Overview: Create and schedule logs from a Data Collector Set

Once you have chosen data collectors that provide you with meaningful information about your system performance, you can store the data as logs for later review.

Note

Log files created from Data Collector Sets in Windows Server 2008 are not backward-compatible with earlier versions of Windows. However, logs created in earlier versions of Windows can be viewed in Windows Server 2008.

Prerequisites for creating logs from a Data Collector Set

To complete this task, ensure that you meet the following requirements:

  • Windows Server 2008 is installed.

  • You are logged on as a member of the local Administrators group, or you are logged on as a member of the Performance Log Users group and have completed the procedure to grant the Log on as a batch job user right to the Performance Log Users group.

  • Windows Reliability and Performance Monitor is running.

  • At least one Data Collector Set has been created and saved (you can use the Data Collector Set that you created in Scenario 3).

Steps for creating logs from a Data Collector Set

By default, a Data Collector Set generates a log file. After creating a Data Collector Set, you can use the Data Management procedures to configure the storage options for each Data Collector Set to include information about the log in the file name, choose to overwrite or append data, and limit the file size of individual logs.

To schedule the Start condition for a Data Collector Set

  1. In Windows Reliability and Performance Monitor, expand Data Collector Sets and click User Defined.

  2. In the console pane, right-click the name of the Data Collector Set that you want to schedule and click Properties.

  5. If you do not want to collect new data after a certain date, select Expiration date and choose a date from the calendar.

Note

Selecting an expiration date will not stop data collection in progress on that date. It will prevent new instances of data collection from starting after the expiration date. You must use the Stop Condition tab to configure how data collection is stopped.

  1. When finished, click OK.

To schedule the Stop condition for a Data Collector Set

  1. In Windows Reliability and Performance Monitor, expand Data Collector Sets and click User Defined.

  2. In the console pane, right-click the name of the Data Collector Set that you want to schedule and click Properties.

  3. Click the Stop Condition tab.

  4. To stop collecting data after a period of time, select the Overall duration check box and choose the quantity and units. Note that your overall duration must be longer than the interval at which data is sampled in order to see any data in the report. Do not select an overall duration if you want to collect data indefinitely.

  5. Use limits to segment data collection into separate logs by selecting the When a limit is reached, restart the data collector set check box. If both limit types are selected, data collection will stop or restart when the first limit is reached.

    • Select Duration to configure a time period for data collection to write to a single log file.

    • Select Maximum Size to restart the Data Collector Set or to stop collecting data when the log file reaches the limit.

Note

If an overall duration is configured, it will override limits.

  1. If you have configured an overall duration, you can click the Stop when all data collectors have finished check box to allow all data collectors to finish recording the most recent values before the Data Collector Set is stopped.

  2. When finished, click OK.

Important

Larger log files result in longer report generation times. If you review your logs frequently to see recent data, we recommend that you use limits to automatically segment your logs. You can use the relog command to segment long log files or combine multiple short log files. For more information about the relog command, type relog /? at a command prompt.

After you have saved the properties for your schedule, the display in the snap-in window changes to show the name of the log, the type of data the log collects, and the output directory and file name where the log is stored. You can double-click the name of the log to add or remove data collectors from it or change the file name, name format, and whether the log overwrites or appends when the data collector is restarted.

Important

Report generation time increases with the size of the log file created by the Data Collector Set. If you review your logs frequently to see recent data, we recommend that you use limits to automatically segment your logs. You can use the relog command to segment long log files or combine multiple short log files.

Next, you can configure how data is archived for the Data Collector Set.

To configure data management for a Data Collector Set

  1. In Windows Reliability and Performance Monitor, expand Data Collector Sets and click User Defined.

To view the System Diagnostics report

  1. Start Windows Reliability and Performance Monitor.

  2. In the navigation tree, expand Data Collector Sets and expand System.

  3. Right-click System Diagnostics and click Start. Data Collection will begin.

  4. In the navigation tree, expand Reports, expand System, expand System Diagnostics, and click the current date.

  5. When data collection and report generation are complete, the System Diagnostics report will appear in the console pane.

Note

This report collects data for 60 seconds. It may take up to an additional 60 seconds for the report to be generated.

Scenario 7: View system stability with Reliability Monitor

Overview: View system stability with Reliability Monitor

Reliability Monitor is a snap-in for the Microsoft Management Console (MMC) that provides a system stability overview and trend analysis with detailed information about individual events that may affect the overall stability of the system. It will begin to collect data at the time of system installation.

In this task, you will review the System Stability Chart and become familiar with the detailed event information that Reliability Monitor uses to calculate the stability index.

Prerequisites for viewing system stability with Reliability Monitor

To complete this task, ensure that you meet the following requirements:

  • Windows Server 2008 is installed.

  • Your computer has been running for a minimum of 24 hours since the installation of the operating system.

  • The RACAgent scheduled task is running (it runs by default on a new installation unless it is manually disabled).

Known issues for viewing system stability with Reliability Monitor

The following known issues may affect your ability to complete this task:

  • Your Windows installation must run for at least 24 hours before data will be displayed in the System Stability Chart.

  • If you perform this task on a new system, you may see only minimal data regarding reliability events. Repeat the task after installing applications and adding hardware to learn more.

Steps for viewing system stability with Reliability Monitor

To start Reliability Monitor

  1. Start Windows Reliability and Performance Monitor.

  2. In the navigation tree, expand Monitoring Tools and click Reliability Monitor.

System Stability Chart

Based on data collected over the lifetime of the system, each date in the System Stability Chart includes a graph point showing the System Stability Index rating for that day. The System Stability Index is a number from 1 (least stable) to 10 (most stable) and is a weighted measurement derived from the number of specified failures recorded over a rolling historical period. Reliability Events in the System Stability Report describe the specific failures. Reliability Monitor maintains up to a year of history for system stability and reliability events. The System Stability Chart displays a rolling graph organized by date.

The top half of the System Stability Chart displays a graph of the System Stability Index. In the lower half of the chart, five rows track Reliability Events that either contribute to the stability measurement for the system or provide related information about software installation and removal. When one or more Reliability Events of each type are detected, an icon appears in the column for that date.

  • For Software Installs and Uninstalls, an Information icon indicates a successful event of that type occurred, or a Warning icon indicates a failure of that type occurred.

  • For all other Reliability Event types, an Error icon indicates a failure of that type occurred.

If more than 30 days of data are available, you can use the scroll bar at the bottom of the System Stability Chart to find dates outside the visible range.

Reliability Events

The Reliability Events recorded in the System Stability Report are as follows:

System Clock Changes
