Web Service Counters for the WWW Service
Applies To: Windows Server 2003, Windows Server 2003 with SP1
The Web Service counters help you determine how well the World Wide Web Publishing Service (WWW service) processes requests. The WWW service is a user-mode service. These counters also reflect the processing that occurs in the kernel-mode driver, HTTP.sys.
Configure these counters to monitor performance for individual Web sites or for all sites on a server (by using the **_**Total instance). Note that some counters that were included with IIS 5.x are now obsolete and, therefore, return a zero value. Obsolete counters are listed in Table D.8 and Table D.9.
Table D.1 describes the Bytes counters for the Web Service performance object.
Table D.1 Bytes (Sent, Received, and Transferred) Counters
| Counter | Description |
|---|---|
Total Bytes Sent |
The number of data bytes that have been sent by the WWW service since the service started. This counter is new in IIS 6.0. |
Bytes Sent/sec |
The rate, in seconds, at which data bytes have been sent by the WWW service. |
Total Bytes Received |
The total bytes of data that have been received by the WWW service since the service started. This counter is new in IIS 6.0. |
Bytes Received/sec |
The rate, in seconds, at which data bytes have been received by the WWW service. |
Total Bytes Transferred |
The total number of bytes of data that have been sent and received by the WWW service since the service started. This counter is new in IIS 6.0. |
Bytes Total/sec |
The sum of Bytes Sent/sec and Bytes Received/sec. |
Table D.2 describes the Files counters for the Web Service performance object.
Table D.2 Files (Sent, Received, and Transferred) Counters
| Counter | Description |
|---|---|
Total Files Sent |
The number of user-mode files that have been sent by the WWW service since the service started. This counter does not include cache hits. Note that this counter does not increment when files are being served from the kernel-mode cache. For more information, see Kernel: URI Cache Hits in Table D.13. |
Files Sent/sec |
The rate, in seconds, at which files have been sent. |
Total Files Received |
The number of files that have been received by the WWW service since the service started. |
Files Received/sec |
The rate, in seconds, at which files have been received by the WWW service. |
Total Files Transferred |

Files/sec |
The rate, in seconds, at which files have been sent and received by the WWW service. |
Table D.3 describes the Anonymous Users and NonAnonymous Users counters for the Web Service performance object. In this context, nonanonymous users are authenticated users.
Note
With Anonymous and NonAnonymous Users counters, IIS6.0 counts each request as a new user. This behavior differs from IIS5.x, which counted each connection as a new user.

The rate, in seconds, at which users have made anonymous requests to the WWW service. |
Total NonAnonymous Users |
The number of users who have made nonanonymous requests to the WWW service since the service started. For more information, see Kernel: URI Cache Hits in Table D.13. |
