In which configuration ate atomic counters supported?

ACI atomic counters are specifically designed to provide granular visibility into traffic flows, including those that traverse the ACI fabric boundary to or from external destinations, identified by their IP addresses. This allows for detailed performance monitoring and troubleshooting of external connectivity.

Atomic counters can monitor traffic between endpoints in different VRFs, but 'endpoint-to-external IP address' is a more specific and primary use case highlighted for this feature.

Atomic counters are used for monitoring, but the 'endpoint-to-EPG policy in Layer 2 scenario' is not the most precise or complete description of a primary supported configuration for atomic counters compared to external IP traffic.

Atomic counters can monitor traffic between endpoints in different tenants, but 'endpoint-to-external IP address' is a more specific and primary use case for which atomic counters are explicitly supported.
