Arista Telemetry Commands

This section assists network administrators in understanding why telemetry alarms exist, and how they are generated. This is not an exhaustive list of interface commands.

Arista EOS uses a few techniques from the EOS SDK API to directly subscribe to event notifications from the switch, for example 'interface down' or 'new route' notifications. When using an event-based notification, you do not have to continually render 'show' commands every few seconds. The EOS SDK gives you the information immediately as soon as the switch has the status.

CAUTION:

Event-based subscription requires the EOSProxySDK agent. For details, see Arista Device Agents.

When the Arista API does not provide information (LLDP statistics), Apstra runs CLI commands at a regular interval to derive telemetry expectations.
