Telemetry and Analytics

Visibility is a critical component to a more efficient cloud-like network. Being able to capture what a network is ‘thinking’ or ‘doing’ is the basis for true network automation and analytics. Legacy networking has long suffered from limitations in network visibility largely due to inefficient polling mechanisms that only provide a limited subset of data. As a result, the operators of legacy networks have been essentially blinded when it comes to true network insight.

Today’s cloud networks operate at a scale where visibility is even more important for efficient operations, and legacy visibility solutions do not meet the cloud requirements. In particular, today’s cloud networks require fine-grained visibility into:

  • Network state in real-time
  • Dynamic workloads in virtualized and containerized environments
  • Advanced monitoring and instrumentation for troubleshooting

A true cloud networking operating system, Arista EOS® has been designed for advanced telemetry from the start. The key to Arista’s telemetry solution is the state-based software architecture of Arista EOS. From the beginning, Arista EOS platforms store all real-time state in one common database, SysDB, easily accessible through powerful APIs and SDKs. With the software infrastructure enhancements to NetDBTM, EOS-based devices are now able to stream every state change from every device into an aggregated network-wide view.

With Arista DANZ, organizations that have requirements to perform critical analytical and monitoring functions with increasingly higher data volumes and higher network bandwidths can maintain security, compliance and reporting for all traffic without the addition of proprietary out-of-band monitoring infrastructure or backhaul networks.

  • Meet security, compliance and reporting requirements even for high data traffic and network bandwidth environments
  • Apply advanced filtering and precision time stamping at wire rate in hardware
  • Integrate with any standard 3rd party API and Application/Network management tools

Real-time state streaming and analytics - Arista EOS and CloudVision bring a modern approach to network telemetry and a replacement for legacy polling mechanisms. CloudVision Analytics engines and CloudVision Telemetry Apps take full advantage of the state streaming infrastructure of EOS and NetDB to give Arista customers an unprecedented level of visibility into their network operations.

Telemetry Tracers - VMtracer, MapReduce tracer and Container tracer are a part of Arista's Telemetry solution that bring deeper workload-level visibility by integrating with distributed applications like big data, cloud, container and virtualized environments.

Advanced Monitoring - Arista’s EOS offers an advanced set of tools for proactive monitoring and instrumentation that provides insight into network hotspot detection using LANZ, programmable event triggers with Advanced Event Monitoring and the ability to capture, aggregate and replicate high volumes of traffic for processing using the integrated DANZ feature set.

Partner Eco-system - Arista’s Telemetry solutions are built on the extensible foundation of EOS and CloudVision, which offer a rich set of JSON and RESTful APIs for easy integration with third party systems. Solutions with VMware, Docker, Microsoft System Center, Openstack, Splunk , HPE, and SAP give customers the flexibility to choose from a best-of-breed ecosystem that integrates the state of the cloud network with Arista real-time telemetry.

In addition to cloud platform integrations above, Arista has a broad ecosystem of technology alliances in packet analysis, security and troubleshooting analytics, and network visibility.

Most provisioning and monitoring tools are reactive and fail to provide fine-grained visibility into network state. Utilizing the state-based architecture of Arista EOS®, NetDBTM state streaming provides a modern and granular approach for capturing the state of each network device into an aggregated network-wide view. With state streaming, every state change on the network is streamed instantaneously to a repository for analytics. Arista customers will have access to both real-time and historic telemetry views of the network in one place and at a level of granularity never before achievable.

For a greater impact on today’s cloud network, the CloudVision® platform includes CloudVision Analytics engines and CloudVision Telemetry Apps that take full advantage of the state streaming infrastructure of EOS and NetDB to give Arista customers improved visibility, faster problem isolation and correction, and greater visibility of network performance over time.

Open Framework

The state-streaming architecture is based on an open industry-standard framework for a variety of integration options. Customers have a choice with the ability to stream the EOS state to the Arista CloudVision platform, to a partner application, or directly to their own backend systems. This streaming architecture is the basis for the YANG-based OpenConfig data models, as well.

Partner Integrations

Arista's Network Telemetry application for Splunk combines multiple data sources from EOS into a centralized Splunk application with pre-built dashboards, views, searches and add-ons for visualizing this network telemetry data.

Know More: With Arista LANZ Track Real Time Congestion

  • Know the answer to the question: Is the network slow?
  • Track sources of congestion in real-time
  • Integrate network performance into applications and middleware

 

Featured Video: Overview of LANZ

Arista Latency Analyzer or LANZ is a breakthrough technology from Arista that tracks sources of congestion and latency with real time reporting in microseconds. Historically if 'the network was slow' administrators would attach a probe/collector and hope the problem happened again. No longer. With LANZ you will know when prior congestion happened, track the sources of congestion, and be able to export real-time events to external applications like Solace Systems middleware. This enables the application layer to make intelligent traffic routing decisions with unprecedented visibility into the network.

A key application of integrated LANZ is for the financial services market where trading plant performance is key. With LANZ the network operations teams and administrators will have more visibility than ever before to know if 'microbursts' are really happening or not. With sub-millisecond reporting intervals, congestion can be detected and application-layer messages sent faster than some products can forward a packet.
