Internet Information Server Performance Monitor Counters (143185)
The information in this article applies to:
- Microsoft Internet Information Server 1.0
This article was previously published under Q143185 We strongly recommend that all users upgrade to Microsoft Internet Information Services (IIS) version 6.0 running on Microsoft Windows Server 2003. IIS 6.0 significantly increases Web infrastructure security. For more information about IIS security-related topics, visit the following Microsoft Web site: 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.
