This document describes a new feature of Arista Analytics that combines Netflow and IPFIX records containing application information with Netflow and IPFIX records containing flow information.This feature improves the visibility of data per application by correlating flow records with applications identified by the flow exporter.

A new feature of Arista Analytics offers the ability to upsample traffic volume sampled by NetFlow V9/IPFIX and SFlow.This feature provides a better visibility of traffic volumes by approximating the number of bytes and packets from samples collected by the NetFlow V9/IPFIX or SFlow sampling protocols. It provides those approximation statistics along with the ElasticSearch statistics. The feature bases the approximations on the flow exporter’s sampling rate or a user-provided fixed factor.

Sampled flow tracking with IPFIX export is supported on most of the Arista platforms. User configured sampling rate is used for sampling in ingress and/or egress direction on the configured interfaces. An EOS software agent on CPU processes samples received from hardware, samples are used to create flow records that are exported to IPFIX collectors. Refer to Sampled flow tracking TOI for additional details.

Network administrators require access to flow information that passes through various network elements, for the purpose of analyzing and monitoring their networks. This feature provides access to IP flow information by sampling traffic flows in ingress and/or egress directions on the interfaces on which it is configured.
