Azure Functions not reporting metrics for functions hosted on AKS

Hello,

I have a customer which is trying to run their application using Azure functions hosted on AKS but is not receiving telemetry from Azure monitor for the functions they're deploying. The application is a .Net app hosted on a Linux VM. Specifically they cannot see ServiceBus-triggered functions metrics: **executions count, errors count, latency distribution** are the bare minimum they would expect.

We tested this by deploying an azure function onto an AKS cluster. Azure does not see this as a Function App resource and does not expose any function app related metrics for it under either the AKS resource or within App Services. We used this to create our test: https://learn.microsoft.com/en-us/azure/azure-functions/functions-kubernetes-keda

#### Expected behavior

Reporting of the metrics expected here: https://learn.microsoft.com/en-us/azure/azure-functions/monitor-functions-reference

Start with the Azure Functions on AKS/KEDA deployment described in the issue and compare its behavior with the Azure Monitor metrics listed in the monitoring reference. Confirm whether Service Bus-triggered execution count, error count, and latency distribution are absent, then determine whether the host repository can provide them or whether the behavior belongs to Azure platform integration.
