SNMP Counters
Applies To: Windows Server 2003, Windows Server 2003 with SP1
IIS exposes the following counters for Simple Network Management Protocol (SNMP) services. These counters are defined in more detail in three .mib files — Inetsrv.mib, Http.mib and Ftp.mib — which you can find in the Windir\System32 folder. Inetsrv.mib is a container object for the other two files and, therefore, does not contain counters. To view the contents of the .mib files, open the files by using Notepad.
You cannot view the SNMP counters in System Monitor or Performance Logs and Alerts. Use WMI or a management information base (MIB) Browser tool instead.
For information about installing and using the SNMP service, see Checklist: Implementing the SNMP service in Help and Support Center for Microsoft® Windows® Server 2003.
