Viewing Outbound QoS reports
The Outbound QoS report summarizes the number of bits per second or packets per second transmitted for either a set of QoS classes (up to seven) or an aggregate total of all classes for the time period specified.
Upgrading from RiOS 8.0.x (or earlier) to version 9.0 or later changes the QoS statistics data. The Outbound QoS report will not show any statistics from a previous configuration.
For details about the report format, see Overview.
What this report tells you
The Outbound QoS report answers these questions:
• Is outbound QoS working correctly?
• How many bits or packets per second were transmitted over the WAN for the QoS classes?
• How many bits or packets per second were sent and dropped for the QoS classes?
The Outbound QoS report might display this message for a traffic class even when QoS is shaping it.
This is because the report limits the data sample display to only the first 1000 classes. When a class falls beyond the first 1000 lines of classes, the report displays no data.
About report graphs
Mouse over a specific data point to see what 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. Due to performance and disk space considerations, the display granularity decreases with time passed since the data was sampled with a granularity of 5 minutes for the day, 1 hour for the last week, and 2 hours for the rest of the month.
To view the Outbound QoS report
1. Choose Reports > Networking: Outbound QoS to display the Outbound QoS page.

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, the following 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.
Units
Select either packets/sec or bps from the drop-down list.
Classes
Select Total or Selected classes from the drop-down list. Selected classes lets you narrow the report by choosing from drop-down lists of classes and remote sites (up to seven). You can’t select a class or a class @ site more than once.
Click Update to change the QoS class selection without updating the chart.
When the report display includes the total classes, the data series appear as translucent; selected classes appear as opaque.
When the report display includes the total classes, the navigator shadows the total sent series. When the report display includes selected classes and remote sites, the navigator shadows the first nonempty sent series. A data series can be empty if you create a QoS class but it has not seen any traffic yet.
Selecting a parent class displays its child classes. For example, the report for an HTTP class with two child classes named WebApp1 and WebApp2 displays statistics for HTTP, WebApp1, and WebApp2.
When a selected class has descendant classes, the report aggregates the statistics for the entire tree of classes. It displays the aggregated tree statistics as belonging to the selected class.
