The Arista Networks Telemetry Application for Splunk is the latest addition to the suite of Telemetry applications available for EOS. Arista EOS provides visibility into network traffic via such mechanisms as Latency Analyzer (LANZ), Data Analyzer (DANZ), sFlow, Path Tracer, VM Tracer, MapReduce Tracer as well as tools like Advanced Event Monitor (AEM) that provides an on-switch record of data-plane forwarding changes.

Arista’s Network Telemetry Application for Splunk augments these with additional network telemetry data pushed to a centralized Splunk server. The Arista Network Telemetry App for Splunk provides pre-built dashboards, views, searches and addons for visualizing this network telemetry data.

As enterprises and service providers evolve from traditional static networks to virtualized on-demand cloud networks, troubleshooting and monitoring toolsets also need to evolve to provide fine-grained visibility into application performance and network wide monitoring capabilities that integrate with both industry standards and customer specific dev/ops solutions. The Arista Networks Telemetry Application for Splunk provides such a solution.

Empowering Deep Insight and Visualization

Traditional syslog and SNMP provide standard interfaces for collection and visualization, but are difficult to scale, index, correlate and visualize in the data center context. The Network Telemetry Application for Splunk proactively exports rich information and statistics in a format that is indexed and stored by the Splunk server. Ad hoc or prebuilt queries provide alerting based on the wealth of data indexed in real-time. This provides network operators the power to automate sifting through large data sets, alerting and pinpointing specific indicators of failure or health degradation.

Product Highlights

Why is the Telemetry Application needed?

  • Monitoring and visualization at scale requires intelligent indexing of large data sets
  • Standard system logging provides minimal device state information
  • Consolidation of rich data from EOS provides real time and historical analytics of network state and performance
  • Centralized, proactive alerting of key events is vital to always on operations
  • Topology and health visualization provides deep insight into current network operations to minimize downtime

What does the telemetry app index?

  • System logging data (syslog)
  • Network topology via LLDP
  • Switch health and inventory data (modules and transceivers) including power consumption, optical light levels and switch capacity
  • Latency Analysis data (LANZ)

Leverages Arista EOS

  • Direct EOS CLI integration for Splunk Universal Forwarder configuration
  • eAPI based Telemetry App gathers system state for export to Splunk
  • Provides rich metrics of network health and performance directly from EOS Sysdb


  • Modular design permits custom Splunk Universal Forwarder configurations for data export
  • Custom data export and facts can be developed by customers or EOS Consulting Services

Supported EOS Platforms and Versions

  • All 1 and 2RU fixed Arista platforms
  • Arista modular systems
