Whichever of the options you select, the Performance Current Data Viewer window opens (Figure 21 on

page 44). The window displays an empty bar chart at first, but then begins to display data based upon the

default settings for the selected report. You can select an alternate chart type from the Chart Options

section at the bottom of the window. Besides Bar Chart, you can select Line Chart or XY Line Chart.

Below the chart is a table that reports the data collected at each data collection point in the collection

interval. You can modify the collection interval in the Poll Interval field (specified in seconds), which is

near the bottom of the window.

For chart input, you can select from the following parameters, which are in the bottom pane of the window:

• Average: The data collected over the specified time period is added together, and the number of

sampling period values is divided by the added value. The sampling period value is used as the poll

interval for current monitoring. 15 minutes is used for history monitoring.

• Nth Percentile: This function needs two parameters: time period (enter a value in seconds in the

Duration field) and percentile value (enter in the Percentile field). When this function is applied, the

data plotted is the percentile value of the number of samples collected over the specified time period.

• Max Nth Percentile: This function is similar to Nth Percentile, but the sample values collected over the

specified time period are sorted in descending order, and the given Nth percentile value is calculated.

• Min Nth Percentile: This function is similar to Nth Percentile, but the sample values collected over the

specified time period are sorted in ascending order, and the given nth percentile value is calculated.

• Cumulative Data: The data plotted in the graph is the data value at any nth interval, and is the sum of

the data values collected in the previous n – 1 intervals.

• Max Value in Set: The maximum value of the data collected over the specified time period is plotted in

the graph.

• Min Value in Set: The minimum value of the data collected over the specified time period is plotted in

the graph.

• None: The raw data collected from the node is plotted as such.

To start collecting data with a new parameter, click Apply. You can start and stop polling with the Start

Polling/Stop Polling button, which is near the bottom of the window (When polling starts, the Stop Polling

button replaces the Start Polling button.)

Note: The window is divided into three panes. To give more room to the graph, click the triangular

down button located at the top left of one of the two lower panes. You can then expand the lower

panes with the triangular up button.
