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.

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

Table 1: Arista Telemetry Commands
Service	Command
Interface counters	`show interface counters`
Interface error counters	`show interfaces counters errors`
Interface status	`show interfaces status`
LLDP neighbors	`show lldp neighbors detail`
BGP Sessions	`show ip bgp summary`
Hostname	`show hostname`
ARP	ARP collection is done using an event-monitor for performance. `show event-monitor arp` and `show ip arp`
MAC Table	MAC address collection is done using an event-monitor for performance. `show event-monitor mac` and `show mac address-table`
Routing table	`show ip route`
Port-channel	`show port-channel summary`
MLAG	`show mlag` and `show mlag interfaces`
