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

Mirror on drop is a network visibility feature which allows monitoring of MPLS or IP flow drops occurring in the ingress pipeline. When such a drop is detected, it is sent to the control plane where it is processed and then sent to configured collectors. Additionally, CLI show commands provide general and detailed statistics and status.

We now support configuration diffs to be generated and to be streamed via OpenConfig.  Please note that there are limitations to using this feature to obtain the correct configuration diff of consecutive configuration changes.  Subsequent sections will explain:

The postcard telemetry (GreenT - GRE Encapsulated Telemetry) feature is used to gather per flow telemetry information like path and per hop latency. For network monitoring and troubleshooting flow related issues, it is desirable to know the path, latency and congestion information for flows at different times.

Prometheus is an open source monitoring and alerting toolkit. It collects and stores metrics from different sources in a time-series database. Prometheus offers a powerful query language, which allows users to analyze and visualize the collected data in real-time. With its robust alerting system, Prometheus can also notify users of potential issues which helps with their timely resolution.

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. The samples are then used to create flow records, which are exported to the configured collectors in the IPFIX format. Egress Flow tracking is supported from EOS-4.29.0F on the DCS-7170B-64C series and supported on 7280, 7500 and 7800 series platforms from EOS-4.31.1".

A DMF fabric consists of a pair of controllers, switches, and managed appliances. This feature allows the user to retrieve the infrastructure metrics (interface counters, CPU usage etc.) associated with all these devices centrally from the controllers using its REST API.
