Using Performance Monitor to Get More System Stats
You see the Terminal Services Active Sessions and Total Sessions counters
listed on the graph, in addition to the CPU Utilization performance counter.
However, the line graph makes it hard to read these performance counters. The
next section shows you how to customize the performance counter data display.
Viewing the Data
The Performance Monitor enables you to view the data in many different ways.
The default screen is the line graph, as shown in Figure 12-7. This display method
is adequate for a few performance counters, but when you have more than three
or four, figuring out what line is for which counter starts to become a little
confusing. Additionally, for certain counters such as Memory Cache Faults/sec
and Cache Bytes Peak, the line graph doesn’t make it easy to understand the
data. Fortunately, Microsoft provides two other methods for viewing the data.
Another method of viewing the data is to use the Histogram display, as
shown in Figure 12-8. To change to this display method, select Histogram Bar
on the View drop-down list that currently shows Line selected. This method
of displaying the data is not much better than the default, but because it relies
on one scale, the counters that report large numbers dwarf counters that report
small numbers. This limitation makes it almost impossible to read some of the
performance counters.

Monitor mean.
