You can use it to check
for changes in system status, look for positive gains after optimization, and even use it to troubleshoot
your system (such as when a network card fails to deliver the throughput you anticipated).
WORKING WITH PERFORMANCE INFORMATION 455
Unlike many of the utilities discussed in this chapter, you can perform setups using the command
line utilities, but actual monitoring usually occurs using the Performance console found in
the Administrative Tools folder of the Control Panel. This chapter focuses on the command line
tasks??”those parts of performance monitoring that other books tend to ignore. However, you??™ll
need to augment this information with a usage guide for the Performance console. This book won??™t
tell you how to use the graphical interface. The following sections describe the command line interface
in detail.
Adding Performance Counters with the LodCtr Utility
Performance monitoring relies on the existence of counters. A counter is a special piece of code that
counts something. The count might reflect the number of times a user accesses a file or makes a network
request. No matter what the counter monitors, it provides output that the various performance
monitoring applications can use to report performance data.
