Viewing Optimized Throughput Reports
The Optimized Throughput report summarizes the throughput for the port, traffic direction, and time period specified.
For details about operating report controls, see Overview.
For details about the Data Store Status information, see the Viewing Performance Details Reports.
The Optimized Throughput report includes Optimized LAN and WAN Link Throughput graphs, that include these statistics that describe data activity for the application and the time period you specify.
Data Series
Description
LAN Average (bps)
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 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 Average (bps)
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 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?
About Report Graphs
Use the mouse to hover over a specific data point to see the y values and exact time stamp were in relation to peaks.
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 the following 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.
For detailed information about data grouping, see Data Grouping.

Control
Description
Time Interval
Select a report time interval of 1 hour (1h), 1 day (1d), 1 week (1w), 30 days (30d), yesterday, last week, or last month.
Time intervals that do not 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 does not 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, the following custom time intervals do not 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 quickly see the newest data and see data points as they are added to the chart dynamically. To display the newest data, click Show newest data.
Port
Select a port from the drop-down list. The list appends the port name to the number where available.
Direction
Select a traffic direction (Bi-directional, WAN to LAN, or LAN to WAN) from the drop-down list.
Group
Select a group from the drop-down list.
