Chart area
The chart provides a graphical representation of the current and peak dispatcher tasks, and the current active and peak active user transactions, over a number of intervals. If enough intervals are available, the chart shows a maximum of 12 intervals: six before and five after the selected interval. Each interval is shown as a separate column in the chart, and shows the time, interval number, and current number of dispatcher tasks. The column for the currently selected interval is shaded. The points on the chart provide an indication of the value, not an actual value. To see the actual values for an interval, hover over a column to display a tooltip that shows actual values.
Data area
The data area shows specific statistical information about the transactions during the selected interval. You can click the columns to change the interval selection.
