Customizing CA Network Flow Analysis › Work with Interface Groups and Aggregations

Work with Interface Groups and Aggregations

You can create and manage interface groups in CA Performance Center, once CA Network Flow Analysis is registered as a data source for CA Performance Center. Custom interface groups can help users get the best results from custom reports and analyses. For example, you may want users to be able to set up custom reports for interface groups that are based on geographic location, interface speed, T1 sites, or load balancing.

You can create and manage interface aggregations in the NFA console. An interface aggregation combines traffic from two or more interfaces so the traffic is reported together. For example, suppose that you have two circuits that are load-balanced and you want to report on the interfaces as a single unit. Aggregations let you report on the interfaces as a single unit without requiring you to create a custom report for that purpose. All aggregations appear in the Interface Index under the label Aggregations.

Note: You can aggregate interfaces only when their data is collected by the same Harvester. Do not attempt to aggregate interfaces from multiple Harvesters.
