Internet Information Server Performance Monitor Counters

ID: Q143185

The information in this article applies to:

Microsoft Internet Information Server version 1.0

SUMMARY

When you install the FTP Server from the Internet Information Server, four new objects are added to the existing list of objects in Windows NT Performance Monitor. This article describes an object called Internet Information Server which contains 10 counters.

Performance Monitor is a graphical tool for measuring the performance of your own computer or other computers on a network. On each computer, you can view the behavior of objects such as processors, memory, cache, threads, and processes. Each of these objects has an associated set of counters that provide information on such things as device usage, queue lengths, and delays, as well as information used for throughput and internal congestion measurements. It provides charting, alerting, and reporting capabilities that reflect current activity along with ongoing logging. You can also open log files at a later time for browsing and charting as if they were reflecting current activity.
