Reporting › Interface Context Views › Stacked ToS Trend

Stacked ToS Trend

The Stacked ToS Trend views show the interface traffic for the top ToS, including the time the traffic occurred.

The example graphic shows a Stacked ToS Trend view that shows a timeline of rates for each listed ToS value. You can configure the view to display rate, utilization, or volume information.

The view includes the following information:

Identifier

Consists of the router name, interface name, and interface description (under the view title). The interface description consists of the ifDescr value by default, so it may be slightly different than the interface description that is shown in CA Network Flow Analysis.

ToS Bands

Show the data rate, data volume, or interface capacity utilization for each Top N ToS that is associated with traffic on the interface.

Time (All Views)

Point in time during data transmission--expressed in hours and minutes (X-Axis).

Measurement Setting:

• Rate: Data transfer rate at each point in time--for example, expressed in kilobits per second (Y-Axis). The rate is calculated by dividing the data volume by the elapsed transmission time.
• Bytes (Volume): Data volume at each point in time--for example, expressed in kilobytes (Y-Axis).
• Percent (Utilization): Percentage of the total interface capacity that the ToS traffic uses (Y-Axis). The utilization percentage is calculated by dividing the data rate by the data speed.

Depending on the data direction, the measured data is inbound to the interface, outbound from the interface, or both.

Legend

Identifies the ToS for each color band by ToS number and label (bottom of the view).

By default, views and reports show the most recent 24 hours of data.

To see the Stacked ToS Trend views in CA Performance Center, go to one of the following locations:

• Interface Pages (with an interface selected): CBQoS tab
• Custom dashboard

Available Actions for This View

You can perform several actions in this view, including the following actions:

• Change the traffic direction, the type of measurement and the view name by editing the view settings. If the view is on a custom interface context dashboard, you can change the interface.
• Zoom in to narrow the time frame.
• Display only the data for a single ToS: Right-click a ToS in the legend at the bottom of the view and click Focus. This menu is available for a view that has multiple ToS values. (This option is active when the view contains multiple ToS values.)
• Hide data for one of multiple ToS values: Right-click a ToS in the legend at the bottom of the view and click Hide.
• Position your cursor over legend items to display explanatory Tooltips.
• Jump to details on a CA Network Flow Analysis Interfaces page by double-clicking a ToS value in the legend.
