Viewing Connection History Reports
The Connection History report shows connection counts for a variety of connection types for the time period specified.
This report includes IPv6 and packet-mode optimized traffic in RiOS 8.5 and later.
For details about the report format, see Overview.
The Connection History report contains these statistics that summarize connection activity.
Connection Type
Description
Optimized
Displays the total connections, including half-open, half-closed (where half-open and half-closed are TCP connection states), idle, established and optimized.
Optimized (Active)
Displays the total active connections that are established and optimized.
Passthrough
Displays the total connections passed through unoptimized.
Forwarded
Displays the total number of connections forwarded by the connection-forwarding neighbor managing the connection.
Optimized (Half Open)
Displays the percentage of half-opened connections represented in the optimized connection total. A half-open connection is a TCP connection that has not been fully established. Half-open connections count toward the connection count limit on the SteelHead because, at any time, they might become a fully open connection.
If you are experiencing a large number of half-opened connections, consider a more appropriately sized SteelHead.
Optimized (Half Closed)
Displays the percentage of half-closed active connections represented in the optimized connection total. Half-closed connections are connections that the SteelHead has intercepted and optimized but are in the process of being disconnected. These connections are counted toward the connection count limit on the SteelHead. (Half-closed connections might remain if the client or server doesn’t close its connections cleanly.)
If you are experiencing a large number of half-closed connections, consider a more appropriately sized SteelHead.
The navigator shadows the optimized series.
What This Report Tells You
The Connection History report answers these questions:
•  How many connections were optimized?
•  How many connections were passed through, unoptimized?
•  What’s the percentage of half-opened connections represented in the total optimized connections?
•  What’s the percentage of half-closed connections represented in the total optimized connections?

About Report Data
The Riverbed system reports on performance for periods up to one month. Due to performance and disk space considerations, the display granularity decreases with time passed since the data was sampled. The data is collected at a 5-minute granularity for the entire month.
