CloudVision Portal release 2017.2.0 introduces support for the network wide Telemetry framework consisting of the

The  Inband Network Telemetry eXport Data (INT XD) feature is used to gather flow, queue, drop telemetry

For network monitoring and troubleshooting flow related issues, it is desirable to know the path, latency, queue and congestion information for flows at different times. The inband telemetry feature(INT), based on Inband Flow Analyzer RFC draft -IFA 2.0 and IFA 1.0(on some platforms) , is used to gather per flow telemetry information like path, per hop latency and congestion. INT is supported for both IPv4 and IPv6 traffic.

InfluxDB telemetry streaming feature enables telemetry data collection with Telegraf on box, and allows streaming

The postcard telemetry(GreenT - GRE Encapsulated Telemetry) feature is used to gather per flow telemetry information like path and per hop latency.

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.
