The Connection History report provides the following 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 con-
nection in which the connection has not been fully established. Half-opened connections
count toward the connection count limit on the appliance 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 appliance.
Half Closed Specifies the total half-closed active connections. Half-closed connections are connections
which the appliance has intercepted and optimized but are in the process of becoming inac-
tive. These connections are counted toward the connection count limit on the appliance. (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 appliance.
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.
