Network In bytes and Idle state / Replica may not go fully into Idle when no requests are made?

[mcrio]

I'm trying to understand when a replica will be in the Idle state.

As per pricing table page: A replica is active when vCPU usage is above 0.01 cores or when data received is above 1,000 bytes per second.

Let's assume vCpu is below 10m.

Having a container app with 1 replica there is always some Network IN traffic shown in the metrics.
I assume this is normal as there must always be some in-cluster traffic to make sure all containers are up.

• When Ingress and Dapr are disabled: Network-In Sum / minute period = ~6.5kB
• When Ingress and Dapr are enabled: Network-In Sum / minute period = ~22kB

Does this traffic (which is internal to the system) count when determining whether a replica is in Idle state? This traffic is produced even with no incoming requests.
