The Network - Connection History report contains the following table of statistics that
summarize connection activity.
What This Report
Tells You The Network - Connection History report answers the following questions:
‹ How many connections were optimized?
‹ How many connections were passed through, unoptimized?
‹ How many connections were half-opened?
‹ How many connections were half-closed?
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.
Packet Type Description
Optimized Connections Specifies the total active connections optimized.
Flowing Connections Specifies the total established active connections.
Half Opened Specifies the total half-opened active connections. A half-
opened connection is a TCP connection in which the
connection has not been fully established. Half-opened
connections count toward the connection count limit on the
HP EFS WAN Accelerator because, at any time, they might
become a fully-opened connection.
If you are experiencing a large number of half-opened
connections, you might consider a more appropriately sized
HP EFS WAN Accelerator.
Half Closed Specifies the total half-closed active connections. Half-
closed connections are connections which the HP EFS WAN
Accelerator has intercepted and optimized but are in the
process of becoming inactive. These connections are
counted toward the connection count limit on the HP EFS
WAN Accelerator. (Half closed connections might remain if
the client or server does not close their connections cleanly.)
If you are experiencing a large number of half-closed
connections, you might consider a more appropriately sized
HP EFS WAN Accelerator.
Active Optimized Specifies the total number of optimized connections with
traffic in the last 60 seconds.
Pass-Through Specifies the total connections passed through, unoptimized,
when the connection limit has been reached.
