About Report Data

The Performance - Data Reduction report includes the following table of statistics that describe data reduction for the application and the time period you specify.

Field	Description
Total Data Reduction %	Specifies the total decrease of data transmitted over the
Over Last Week	WAN.
Peak Data Reduction % Over	Specifies the peak decrease in data transmitted over the
Last Week	WAN.
Peak Data Reduction	Specifies the time that the peak data reduction occured.
Occured At
Capacity Increase	Specifies the increase in the amount of the data that can be
	transmitted over the WAN.

The Performance - Data Reduction report answers the following questions:

‹What was the total reduction in the amount of data that can be transmitted for each application?

‹What was the peak reduction in the amount of data transmitted for each application?

‹What was the total capacity increase for the application and time period specified?

In bar-graph and line-graph reports, the x-axis (or tick mark) plots time, according to the interval you select. The y-axis plots the metric of interest, such as gigabytes (GB) of bandwidth, percent (%) of data reduction, connection counts, and the like.

A diamond icon above the top margin of the graph points to the value on the x-axis (the time) at which the peak occurred.

A diamond icon outside the right margin of the graph points to the value on the y-axis (for example, the percent) that is the average value for the time period selected.

Pie chart graphs do not indicate peaks or averages. Pie chart graphs represent the aggregate for the time period selected.

The HP EFS WAN Accelerator system polls bandwidth and connection metrics every second and can report on performance for periods as long as one year. However, due to performance and disk space considerations, data representation in reports for periods longer than the Last 5 Minutes are interpolated from aggregate data points.
