Viewing Optimized Throughput reports
The Optimized Throughput report summarizes the throughput for the port, traffic direction, and time period specified.
For details about the report format, see Overview.
You can view optimization statistics for SaaS applications. This report lists the optimized traffic by SaaS application instead of by port number, and the ID for the SaaS application is listed in the Port column. To configure SaaS applications for optimization by the SteelHead, see Configuring the Legacy Cloud Accelerator and Activating SaaS applications.
SaaS application statistics are not included with the overall statistics for port 443 and port 80.
When using a role-based management (RBM) user, ensure that the RBM user has at least Read-Only permissions for the Cloud Optimization role, or the user will not be able to view the SaaS application names.
To find the definition of the application ID that is listed in the Port column, open the Optimization > Cloud Accelerator page. The ID (for example, SFDC) and application name (for example, Salesforce.com) are listed in the Application ID and SaaS Application Control fields.
The Optimized Throughput report includes LAN and WAN link throughput graphs that include these statistics describing data activity for the port, traffic direction, and the time period you specify.
Data series
Description
LAN Peak
Displays the peak data activity.
LAN P95
Displays the 95th percentile for data activity. The 95th percentile is calculated by taking the peak of the lower 95 percent of inbound and outbound throughput samples.
LAN Average
Displays the average throughput.
RiOS calculates the LAN average at each data point by taking the number of bytes transferred, converting that to bits, and then dividing by the granularity.
For instance, if the system reports 100 bytes for a data point with a 10-second granularity, RiOS calculates:
100 bytes * 8 bits/byte / 10 seconds = 80 bps
This calculation means that 80 bps was the average throughput over that 10-second period.
The average that appears below the LAN Average is an average of all displayed averages.
WAN Peak
Displays the peak data activity.
WAN P95
Displays the 95th percentile for data activity. The 95th percentile is calculated by taking the peak of the lower 95 percent of inbound and outbound throughput samples.
WAN Average
Displays the average throughput.
RiOS calculates the WAN average at each data point by taking the number of bytes transferred, converting that to bits, and then dividing by the granularity.
For instance, if the system reports 100 bytes for a data point with a 10-second granularity, RiOS calculates:
100 bytes * 8 bits/byte / 10 seconds = 80 bps
This calculation means that 80 bps was the average throughput over that 10-second period.
The average that appears below the WAN Average is an average of all displayed averages.
The navigator shadows the WAN Peak series.
What this report tells you
The Optimized Throughput report answers these questions:
• What was the average WAN and LAN throughput?
• What was the peak WAN and LAN throughput?
• Which SaaS applications are being optimized? (RiOS 9.5 and later)
About report graphs

About report data
The Riverbed system reports on performance for periods up to one month. 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. The Optimized Throughput report displays these data granularities:
• Last 1 hour's worth of data is available at 10-second granularity.
• Last 1 day's worth of data is available at 5-minute granularity.
• Last 1 week's worth of data is available at 1-hour granularity.
• Last 1 month's worth of data is available at 2-hour granularity.

Description
Time interval
Select a report time interval of 5 minutes (5m), 1 hour (1h), 1 day (1d), 1 week (1w), All, or type a custom date. All includes statistics for the last 30 days.
Time intervals that don’t apply to a particular report are dimmed.
For a custom time interval, enter the start time and end time using the format YYYY/MM/DD HH:MM:SS.
Because the system aggregates data on the hour, request hourly time intervals. For example, setting a time interval to 08:30:00 to 09:30:00 from 2 days ago doesn’t create a data display, whereas setting a time interval to 08:00:00 to 09:00:00 from 2 days ago will display data.
When you request a custom time interval to view data beyond the aggregated granularity, the data is not visible because the system is no longer storing the data. For example, these custom time intervals don’t return data because the system automatically aggregates data older than 7 days into 2-hour data points:
• Setting a 1-hour time period that occurred 2 weeks ago.
• Setting a 75-minute time period that occurred more than 1 week ago.
You can view the newest data and see data points as they’re added to the chart dynamically. To display the newest data, click Show newest data.
Direction
Select a traffic direction from the drop-down list:
• Bi-Directional—traffic flowing in both directions
• WAN to LAN—inbound traffic flowing from the WAN to the LAN
• LAN to WAN—outbound traffic flowing from the LAN to the WAN
Port
Select a port or All to display all of the TCP ports on which the SteelHead has seen traffic. The list appends the port name to the number where available.
If your SteelHead appliance is SaaS-enabled, select the SaaS application from the drop-down list. To see the definition of the SaaS application (for example, SFDC in the drop-down list refers to Salesforce.com), log in to the Cloud Portal. The application names and acronyms are listed in the SaaS Services Summary pane.
