Performance metrics graphics
Each command in the Graphs menu of the Engine Monitor dialog box opens a graph of a different metric. Although each graph measures a different aspect, all have the same basic design.
The numbers on the left are ranges for the metrics. They are automatically adjusted to show different ranges for the actual numbers. For example, the graph for bytes per second might range from 4000 to 7000, with a horizontal line at every 500.
The numbers at the bottom are times at which the graph is updated, in hh:mm:ss format. These times depend on the interval selected for updates. The breaks differ slightly because of the small amount of time it takes to process the information and change the display.
