Reporting › Interface Context Views › Stacked Protocol Trend

Stacked Protocol Trend

The Stacked Protocol Trend views in CA Performance Center show the top protocols that are used the most heavily for traffic on the selected interface. The views also show when the traffic occurred.

The example graphic shows a Stacked Protocol 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.

Protocol Bands

Show the data rate, data volume, or interface capacity utilization for each Top N Protocol 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 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 protocol uses (Y-Axis). The utilization percentage is calculated by dividing the data rate by the data speed.

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

Legend

Identifies the protocol for each color band by protocol keyword and tcp/udp port (bottom of the view).

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

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

• Interface Pages (with an interface selected): IP Performance tab or 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 protocol: Right-click a protocol in the legend at the bottom of the view and click Focus. This menu is available for a view that has multiple protocols. (This option is active when the legend contains multiple protocols.)
• Hide data for one of multiple protocols: Right-click a protocol 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 protocol in the legend at the bottom of the view.

Find Protocol Trend Data in NFA Console Views and Reports

You can display protocol volume in the NFA console in trend charts or stacked trend charts for a selected interface:

• Overview -- Report type: Overview. Presentation menu options: Mixed Chart; Volume.

  Views: Stacked Protocol Trend (In and Out) for the Top N Protocols, plus other overview views.

• Top N Protocols, Stacked Trends -- Report type: Protocols. Filter: Top N Protocols. Presentation menu options: Stacked Trend Chart; Volume.

  Views: Stacked Trend for the Top N Protocols (In, Out, and Total).

• Top N Protocols, Trends -- Report type: Protocols. Filter: Top N ToS. Presentation menu options: Trend Chart; Volume.

  Views: Trend (In, Out, and Total) for each of the Top N Protocols.

• Single Protocol -- Report type: Protocols. Filter: Single protocol.

  Views: (Depending on the selected report subtype): trends, stacked trends, trend summaries, and multi-trend summaries for protocols, protocol hosts, and protocols in conversations.
