Windows Performance MonitorYou can use Windows Performance Monitor to examine how programs you run affect your computer's performance, both in real time and by collecting log data for later analysis.

Windows Performance Monitor uses performance counters, event trace data, and configuration information, which can be combined into Data Collector Sets.

Performance counters are measurements of system state or activity. They can be included in the operating system or can be part of individual applications. Windows Performance Monitor requests the current value of performance counters at specified time intervals.

Event trace data is collected from trace providers, which are components of the operating system or of individual applications that report actions or events. Output from multiple trace providers can be combined into a trace session.

Configuration information is collected from key values in the Windows registry. Windows Performance Monitor can record the value of a registry key at a specified time or interval as part of a log file.

Creating Data Collector SetsA Data Collector Set is the building block of performance monitoring and reporting in Windows Performance Monitor. It organizes multiple data collection points into a single component that can be used to review or log performance. A Data Collector Set can be created and then recorded individually, grouped with other Data Collector Set and incorporated into logs, viewed in Performance Monitor, configured to generate alerts when thresholds are reached, or used by other non-Microsoft applications. It can be associated with rules of scheduling for data collection at specific times. Windows Management Interface (WMI) tasks can be configured to run upon the completion of Data Collector Set collection.

Data Collector Sets can contain the following types of data collectors:

l Performance counters

l Event trace data

l System configuration information (registry key values)

You can create a Data Collector Set from a template, from an existing set of Data Collectors in a Performance Monitor view, or by selecting individual Data Collectors and setting each individual option in the Data Collector Set properties.

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.



l Membership in the local Performance Log Users or Administrators group, or equivalent, is the minimum required to complete these procedures.

l If you are adding counters to an existing Data Collector Set that is configured to run as another user, you will be prompted to enter the user name and password each time you modify the properties of the Data Collector Set.

l To add performance counters from a remote computer, the Performance Logs and Alerts firewall exception must be enabled on the remote computer. In addition, members of the Performance Log Users group must also be members of the Event Log Readers group on the remote computer.



Data Collector Set PropertiesTo view or modify the properties of a Data Collector Set after it has been created, you can:

l Select the Open properties for this data collector set check box at the end of the Data Collector Set Creation Wizard.

l Right-click the name of a Data Collector Set, either in the MMC scope tree or in the console window, and click Properties in the context menu.

Tab Details

General

The General tab includes the description and keywords associated with the Data Collector Set. If you created the Data Collector Set from a template that had a description and keywords, they will be included here. If you created a custom Data Collector Set, you can add data here to help you identify it later, or to provide more information to others if you export it as a template.

You can change what user the Data Collector Set will Run As by clicking Change… and entering a user name and password.

Important The Data Collector Set must run as a user with administrative credentials or as a member of the Performance Log Users group.Note If you configure the Data Collector Set to run as a user with a higher level credentials than the currently logged on user, you will be prompted to enter the user name and password of the account the Data Collector Set is configured to run as when you change its properties.

In addition to defining a root directory for storing Data Collector Set data, you can specify a single Subdirectory or create a Subdirectory name format by clicking the arrow to the



Directoryright of the text entry field. The Example directory at the bottom of the page provides a real-time sample of the directory and/or subdirectory where the Data Collector Set data will be stored.

Security

You can change the permissions of groups or users for the Data Collector Set by selecting the Group or User name and then selecting the Allow or Deny check boxes for each permission type. To add, remove, or change permission types, click the Advanced button.

Note These permission changes, including changes implemented in the Advanced section, apply only to the Data Collector Set.

SchedulingThe schedule tab includes options for configuring when data collection begins. For more information, see Scheduling and Managing Data in Windows Performance Monitor. Use the Stop Condition tab to configure stopping data collection.

Stop Condition

A single stop condition, or a combination of multiple criteria, can be used to automatically halt or restart the collection of data from a Data Collector Set.

Select the check boxes to choose one or all of the stop conditions you want to apply to the Data Collector Set. If no stop conditions are selected on this tab, the Data Collector Set will collect data from the time it is started (either manually or automatically) until it is manually stopped.

Overall duration causes the Data Collector Set to stop collecting data when the configured time has elapsed. The overall duration setting takes precedence over any settings defined as limits.

Limits can be used instead of, or in addition to, the overall duration stop condition.

To automatically restart collection of the Data Collector Set when limits for duration, size, or both are reached, select the check box. When used in combination with the overall duration stop condition, configuring automatic restarts will cause the data to be collected in separate log files for each specified time period or size until the overall duration stop condition is met.

TaskYou can run a Windows Management Instrumentation (WMI) task upon completion of the Data Collector Set collection by entering the command in the Run this task when the data collector set stops box. Refer to WMI task documentation for options.
