Selection List
The Selection List reflects the item (System, Server, Service),
statistical category, and graph type of each defined data series. These
display in the List’s three columns, described below:
• Items: The specific System, Server, or Service selected in the
Statistics box's Items list.
• Statistics: The statistical category selected in the Statistics box's
Available Statistics list.
• Graph Type: The graph type name selected in the Graph
Options' Style drop down menu.
Window Options
The Window Options box includes the following controls:
• Single Graph: Displays all data series in a single composite
graph.
• Multiple Graphs: Displays each data series in its own graph.
• X Gridlines: Displays the graph's vertical grid lines (the default
is enabled).
• Y Gridlines: Displays the graph's horizontal grid lines (the
default is enabled).
NOTE: Statistics
gathering generates
network overhead, and
increasing the refresh
rate (that is, lowering the
Refresh Intervals value)
increases that overhead. • Refresh Interval(s): The refresh or update rate of the graph in
seconds (the default is five seconds).
• Maximum Data Points: The number of data points displayed in
the graph. After the maximum number of data points is
displayed, new data points are added to the right of the graph and
the oldest data point is displaced off the left side of the graph.
The graph can display between 1 and 1000 data points, and the
default is 100.
