11. In the bottom pane of Performance Monitor, notice that the value in the Scale column of the
Processor Queue Length counter is 10. This value means the graph is showing the counter's
actual value multiplied by the scale value. In this case, if the graph shows a value of 30 for
Processor Queue Length, the actual value is 3. To adjust the scale, right-click Processor
Queue Length and click Properties . In the Data tab, you can select the color, width, style,
and scale of the line graph for the counter (see Figure 13-14). Click the Scale list arrow, click
1.0 in the list, and then click OK .

You might want to change the scale value for a counter so that the line
on the graph is more distinct and shows variations in the counter value
more clearly.

Data Collector Sets A data collector set can contain a variety of types of information col-
lected and displayed as a graph or report. Information types you might find in a data collector
set include the following:
• Performance counters —These system performance indicators used to view real-time data
are also used in data collector sets.
• Counter alerts —Events generated when a counter falls below or exceeds a specified thresh-
old. For example, you can create an alert to log an entry in the Application log if the %
Processor Time counter exceeds 90%.
• Event traces —Logs information based on system or application events.
• System configuration —Monitors and records changes to Registry keys.

Recall that a common use of data collector sets is collecting performance data to establish
a baseline. Predefined data collector sets can be run as they are or used as templates to create
