Web Service Object

The Web Service object counters installed with Internet Information Service monitor file transfer rates, bandwidth usage, and connection rates.

You can view performance data for all instances of this object (using the _Total instance) or for specific instances, such as the Default Web Site or Administration Web Site instances.

In addition to these counters, counters supplied by the Internet Information Services Global performance object combine data for the Web service with the performance data they report for IIS as a whole. For more information, see the Internet Information Services Global object.
