Performance objects and counters
obtains performance data from components in your computer as those components are utilized. That data is described as a performance object and is typically named for the component generating the data. For example, the Processor object is a collection of performance data about processors on your system.
A range of performance objects are built into the operating system, typically corresponding to the major hardware components such as memory, processors, and so on. Other programs may install their own performance objects. For example, services such as WINS or server programs such as Microsoft Exchange provide performance objects, and performance graphs and logs can monitor these objects.
Each performance object provides counters that represent data on specific aspects of a system or service. For example, the Pages/sec counter provided by the Memory object tracks the rate of memory paging.
Although your system may typically make available many more objects, following are the most frequently used objects:
The following table describes the services or features of that you may be using in your configuration and their corresponding performance objects.
For a description of the data provided by a particular counter that is associated with a performance object, click Explain in the Add Counters dialog box. For information about adding counters, see To add counters to System Monitor
Although some objects (such as Memory and Server) have only a single instance, some performance objects can have multiple instances. If an object has multiple instances, you can add counters to track statistics for each instance, or for all instances at once.
Depending on how the counter was defined, its value may be:
The combination of computer name, object, counter, instance, and instance index is known as the counter path. The counter path is typically shown in the tools as follows:
The computer_name is optional. If you do not supply a name, will use the name of the local computer by default.
