Performance Monitor Objects and Counters
SNMP MIBS

You can monitor the health and performance of an IAS server using either Windows 2000 Performance Monitor or the Windows 2000 SNMP agent and the built-in support for industry-standard RADIUS MIBs.

Performance Monitor Objects and Counters

Windows 2000 Performance Monitor allows you to monitor the health of your IAS server through a series of counters for the following performance-monitor objects:

  • IAS Accounting Clients Object.

  • IAS Accounting Server Object.

  • IAS Authentication Clients Object.

  • IAS Authentication Server Object.

IAS Accounting Clients Object

The IAS Accounting Clients performance object is installed by the Internet Authentication Service (IAS). IAS uses the Remote Authentication Dial-In User Service (RADIUS) protocol to perform remote authentication. IAS performance objects report activity for servers or clients, including user authentication, authorization, and accounting.

When selecting counters for this object, note that each client represents a separate instance.

SNMP MIBS

Windows 2000 supports objects in the following MIBs:

  • RADIUS Accounting Server MIB: RFC 2621.

  • RADIUS Accounting Client MIB: RFC 2620.

  • RADIUS Authentication Server MIB: RFC 2919.

  • RADIUS Authentication Client MIB: RFC 2618.

SNMP MIB support for RADIUS objects is installed when IAS is installed. For details about the objects within each MIB, see the appropriate RFC.
