As you know, Resource Monitor can perform
some of the basic performance monitoring you want on a server. The Reliability
and Performance Monitor is basically an extension of the Performance Monitor that was
available in previous Windows versions. This tool still allows you to gather performance
metrics, but it also has the ability to track server reliability and stability statistics. When
you launch the Reliability and Performance Monitor (by choosing Start | Administrative
Tools | Reliability and Performance Monitor), you see a Resource Overview (Figure 7-21),
a summary view of your server??™s major performance metrics. It displays in realtime the

CPU utilization, memory hard fault statistics, as well as disk and network activity and
utilization. You can drill down further to get more specifics by double-clicking the desired
category under the graphs. For example, to find out what processes are taking up
CPU cycles, double-click CPU and you will see a process list similar to what you would
see in Task Manager (Figure 7-22).
As with Performance Monitor, the Resource Monitor in WSRM lets you add performance
counters and track them as you normally would, except in the Reliability and
Performance Monitor, the selected counters can also be used to create data collector sets
(discussed later in the chapter).
