The Network - QoS Statistics report contains the following Data table of statistics that
summarize current connections.
What This Report
Tells You The Network - QoS Statistics report answers the following questions:
‹ How many bytes transmitted over the WAN for the QoS class?
‹ How many data packets were dropped for the QoS class?
‹ When did the peak data transmission occur for the QoS class?
About Report
Graphs 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.
About Report Data 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.
Field Description
Data Sent Specifies the total amount of data sent over the WAN for the
QoS class.
Data Dropped Specifies the total amount of data packets that were dropped
for the QoS class.
Peak Data % Over Last Week Specifies the peak amount of data transmitted over the last
week.
Pass Data % Occurred At Specifies when the peak data transmission occurred.
