Top Protocols (Table)

The Top Protocols (Table) views show rate, volume, or utilization for the top 10 highest-volume IP protocols for traffic on a particular interface. A table shows data for the protocols--and therefore, the applications--that account for the most traffic on the selected interface. For example, use this information to compare the amounts of data or level of utilization for particular applications on the interface.

The example graphic shows a Top Protocols (Table) view that is set to show the volume of flow for each listed protocol. You can configure the view to display rate, utilization, or volume information.

The view contains an interface identification string and a table. The table contains a row for each protocol with the protocol name (keyword and TCP/UDP port assignment) and the following rate, volume, or utilization information (by default):

• Rate: Maximum rate of outbound data (Maximum From) and inbound data (Maximum To) for each protocol; average rates of total data (Average Total), outbound data (Average From), and inbound data (Average To) for each protocol.
• Volume: Number of bytes/megabytes of outbound data (From), inbound data (To), and all data (Total) for each protocol.
• Utilization: Maximum percentage of interface capacity that is utilized by the outbound data (Maximum From) and inbound data (Maximum To) for each protocol; and the average utilization by inbound data (Average From), outbound data (Average To), and total data (Average Total) for each protocol.

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

To see a Top Protocols (Table) view in CA Performance Center, add it to a custom dashboard.

Available Actions for This View

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

• Change the type of measurement, the view name, and the interface by editing the view settings.
• Re-sort the table data by clicking a column heading. Click again to toggle between descending and ascending order.
• Change the Max Per Page value to show more or fewer items on each table page.
• Change the columns that are shown in the table: Click near a column border, click Columns, then choose the columns that you want to display.
• Click a name to jump to a pre-filtered Interfaces report in CA Network Flow Analysis.

Find Protocol Tables in the NFA Console

You can display tables of protocol volume data in the NFA console for a selected interface:

• Top N Protocols -- Report type: Protocols. Filter: Top N Protocols. Presentation menu options: Summary Table; Volume.

  View: Protocol Summary Table for the Top N Protocols, plus other overview views.

• Protocols for a Single Host -- Report type: Hosts. Filter: Single host. Report subtype: Protocols. Presentation menu options: Summary Table; Volume.

  View: Host Protocol Summary Table for the single host.

• Protocols for a Single Conversation -- Report type: Conversations. Filter: Single conversation. Report subtype: Protocols. Presentation menu options: Summary Table; Volume.

  View: Conversation Protocol Summary Table for the single conversation.
