Windows NT Server 4.0 includes a Performance Monitor tool which is used for monitoring computer performance. When you monitor a system, you actually monitor its parts. A set of counters exists for the processor, memory, cache, hard disk, processes, and other parts that produce statistical information. Certain counters are standard; others are added with the installation of new software.

You can choose to chart performance when you want to, or you can set system alerts for any specific counters. By setting alerts, you can choose to have any of the following responses occur when a counter reaches a predefined limit:

• The active monitoring view for Performance Monitor changes to the Alert view and the Alert window displays information about the reason for the alert.
• The event that caused the alert status is logged in the Application log of the Event Viewer.
• An alert message is broadcast over the network by the server.

You do not need special privileges to open Performance Monitor. However, you do need to be logged on as a member of the Administrators group to use the diskperf command.

The diskperf command turns the counters for disk activity on and off. Diskperf works for a local or a remote computer. After restarting the computer, you can use Performance Monitor to view disk performance data.

To activate the physical and logical disk counters:

1. Log on as a member of the Administrators group.
2. At the command prompt, type diskperf to view Help information on how to turn diskperf on and off and how to specify a remote computer's name.
3. Follow the instructions to turn diskperf on or off.
4. To activate the disk performance counters, reboot the server.

NOTE

Activating object counters for performance monitoring will increase disk access time. When you are finished with diskperf you should turn it off.

To start Performance Monitor, use this procedure:

1. From the Start Menu, choose Programs.
2. Choose the Administrative Tools program group, then select Performance Monitor.

To view counters, follow these steps:

1. Choose File, New Chart.
2. Choose Edit, Add to Chart. The Add to Chart dialog box appears.
3. Select an object from the Object list. For example, you might select WinSock Proxy Server. The counters for that object appear in the Counter list.
4. Select a counter from the Counter list, and then choose Add.
5. Repeat Steps 2, 3, and 4 to add additional counters.
6. When all counters have been added, choose Done.

The display returns to the Performance Monitor and information about the selected counters is displayed.

Each component will have its own list of performance counters. Following are lists of the counters broken down by server. Each counter is accompanied by a brief description of its function.

Table B.1 lists all the .htx variables available for statistics. The Content Index performance object variables begin with CiAdminIndex while Http Content Index object variables begin with CiAdminCache.

The role of the Membership System is to provide support services for MSIC components such as the Microsoft Commercial Internet System News Server, Internet Address Book Server, and Microsoft Commercial Internet System Mail Server. Therefore, many of the necessary performance monitor counters are provided by these applications rather than Membership System. Membership System includes performance counters for the Membership Agent on the Membership Backend, for Membership Broker, and for the Membership Simulator.

The Membership Agent maintains counters under the Membership Agent Object, which utilizes the following Performance Counters (see Table B.11).
