CCELERATOR REPORTS AND
The Connection History report contains the following table of statistics that summarize
connection activity.
What This Report
Tells You
The 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?
Packet Type Description
Total Optimized Specifies the total active connections optimized.
Established 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 connec-
tion 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 con-
nections, 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 pro-
cess 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 con-
nections, 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.
