Counters Provided by Windows and by IIS

Windows Server 2003 provides hundreds of counters. Frequently used performance objects include cache, memory, process, and server. For more information about Windows performance objects and counters, see "Performance objects and counters" in Help and Support Center for Windows Server 2003.

When you install IIS, you automatically install the IIS performance counters, which include the following:

  • Web Service counters to monitor the World Wide Web Publishing Service (WWW service).

  • Web Service Cache counters to monitor the WWW service cache.

  • FTP Service counters to monitor the File Transfer Protocol (FTP) service.

  • Active Server Pages counters to monitor applications that run as Active Server Pages (ASP pages).

If you use Simple Network Management Protocol (SNMP) services to monitor your Web services, IIS makes available a set of counters by means of SNMP. They include SNMP FTP service counters and SNMP HTTP service counters, which you can use to monitor an SNMP WWW service. However, you cannot view the SNMP counters in System Monitor or Performance Logs and Alerts; you must use Windows Management Instrumentation (WMI) or a management information base (MIB) browser tool instead. For more information about specific IIS counters, including how to locate and view the SNMP counters, see IIS 6.0 Performance Counters.
