Arista offers a next-generation approach to TAP Aggregation -- network observability -- that enables, pervasive network visibility, zero-trust security monitoring and contextual analytics for high density, non-blocking 10/25/40/50/100GbE networks at any scale– all powered by Arista Data ANalyZer (DANZ) monitoring software solutions to deliver cloud-scale visibility with Ethernet economics

Arista Network Observability Product portfolio comprises of:

  • DANZ Monitoring Fabric (DMF) - is a next-generation, controller-based network packet broker (NPB) with integrated advanced services, predictive analytics and scale-out packet capture.
  • DANZ EOS - enables a switch-based tap aggregation solution with familiar Arista EOS® and Arista CloudVision® operational model.

CloudVision Universal Network ObservabilityTM(CV UNOTM) is Arista’s modern, multi-domain network observability platform that integrates application visibility with CloudVision’s already powerful network telemetry base in providing unparalleled insights into application and workload performance across data centers, campuses, and wide area networks. It harnesses the power of NetDL architecture and AVA-driven proactive analysis and prescriptive recommendations, accelerating root-cause identification and propelling rapid issue resolution. This innovative solution proactively reduces human error, streamlines issue resolution for unforeseen events and provides precise root cause analysis of network events and their impact on application delivery.

Key CV UNO benefits:

  1. Integrated Workload Application and Infrastructure Visibility
    CV UNO constructs a composite picture of the entire network and application environment - essentially an application-to-network graph. This graph is continually refreshed and stored in a time-series database, providing a dynamic, historical account of the environment's evolution and state, ensuring deep visibility and understanding of application flows through the network at any given moment.
  2. Proactive Risk Analysis
    CloudVision’s change control workflows (including AVD) leverages CV UNO’s application intelligence, empowering organizations to scrutinize potentially disruptive network changes rigorously before their deployment into production and mission-critical networks, ensuring operational resilience and stability.
  3. Realtime Impact Analysis
    When an application performance is impacted, CV UNO, without deploying any host-based agents, is able to quickly help the operator or engineer answer the critical question “is the issue on the network or in the application?” by driving to the accurate root cause of the issue, thereby reducing the resolution time and simplifying cross-functional coordination for the operations team.

CV UNO - Arista’s Platform for Network Observability

CloudVision® Universal Network Observability™ Enabling Self-Diagnostic Networks

Available as a premium feature set on Arista CloudVision as-a-Service(CVaaS), CV UNO leverages one or more CV UNO Sensor VMs, strategically deployed on-premises to collect, normalize, and meticulously curate flow/SNMP data from diverse sources such as physical/virtual compute and third-party network devices. This holistic data is then coupled with CloudVision’s deep view of the networking state and stored into NetDL. CV UNO then harnesses machine intelligence-based analysis on this composite NetDL data to identify application and topology-aware correlations across events, application behavior changes, and application flow anomalies. This advanced functionality accelerates impact analysis and expedites issue resolution with unprecedented efficiency delivering a comprehensive, 360o observability powered by the following key feature highlights:

  • Private cloud visibility, leveraging API integration with VMware vCenter to augment application, flow and event information into NetDL data
  • Application Discovery workflows to discover and classify applications
  • Application Dashboard page, that shows all the applications, application health, performance, services, critical events, top bandwidth consumers and more
  • Application Dependency Mapping topology overlaid with flow metrics (like latency, data usage etc) to not only visualize interaction between application services but also enable faster root cause analysis
  • Application Flow graph, that visualizes directional, bandwidth-aware, inter-service application flows
  • DANZ Monitoring Fabric (DMF) as a Data source to support collection of end-to-end TCP analysis and flow data generated from DMF
  • Enhanced 3rd Party Device Visibility to also support flow data collection from 3rd party devices into NetDL. This extends CV’s SNMP based 3rd Party Device support.
  • End-to-End Visualization that elevates CV’s network topology visualization to now display physical / virtual end hosts in the topology, showing how applications are connected to the network and also identifying application flow-level potential bottlenecks or performance issues.
  • Enhanced CV’s Fault / Anomaly Detection, Event Correlation, Inference and Alerting algorithms to also take application context, application events, end-to-end TCP analysis events in consideration in addition to CV’s network-centric events.

Predictive, App-aware, Flow Intelligence for Pervasive Observability

DANZ Monitoring Fabric (DMF) is a next-generation network packet broker (NPB) architected for pervasive, organization-wide visibility and security, delivering multi-tenant monitoring-as-a-service. DMF enables IT operators to pervasively monitor all user, device/IOT and application traffic (north-south and east-west) by gaining complete visibility into physical, virtual and container environments. Deep hop-by-hop visibility, predictive analytics and scale-out packet capture — integrated through a single dashboard — enables simplified network performance monitoring (NPM) and SecMon workflows for real-time and historical context, delivering a one-stop visibility solution for on-premise data centers, enterprise campus/branch and 4G/5G mobile networks.
