Exchange 2000 is integrally linked to Windows 2000, so many of the tools you use to monitor Exchange Server and the network are part of the Windows 2000 operating system. You can use the Windows 2000 tools Performance console, Netdiag, Task Manager, and Network Monitor to monitor performance.

• Performance Console
  System performance in Exchange is monitored in part by the Performance console, which includes System Monitor and Performance Logs and Alerts.
• System Monitor
  System Monitor displays graph, histogram, or report displays of system data. System Monitor provides short-term viewing of data, and information for troubleshooting and diagnosis. It includes tools such as physical hard disk counters and workload balance tools.
  Performance objects that are associated with a resource or service that you can monitor contain at least one performance counter. You can view selected performance counters individually or in relation to other available counters.

  Note Monitoring large numbers of counters can create overhead. To reduce this burden, you can either display data in report view when collecting information from a large numbers of counters, or direct data to a binary log or view the data in System Monitor as it is written to the log.

• Performance Objects
  When you monitor Exchange 2000 performance, you often rely on data contained in Windows 2000 performance objects, which is collected from components in your computer and monitored in Windows 2000 System Monitor and Performance Logs and Alerts.

  As a component functions in your system, it generates performance data. The data is formulated into performance objects that are typically named for the component generating the data. For example, the Processor object is a collection of performance data about processors on your system.
  A range of performance objects is built into the Windows 2000 operating system and typically corresponds to the major hardware components such as memory, processors, and many more. Other applications might install their own performance objects as will happen with Exchange 2000. Table: Exchange services or resources monitored using System Monitor

  Each Exchange 2000 performance object has at least one associated counter, which you can configure to monitor instances involving any number of server actions.
  For more information about the function of a counter for a specified performance object, click Select Counters from List, select a counter, and then click Explain.
