Support for custom metrics

[denniszielke]

For my custom applications I would like to ensure metrics scrapping of my own metrics endpoints in the application (see https://docs.microsoft.com/en-us/azure/azure-monitor/containers/container-insights-prometheus-integration).

End goal would be to gain observability into my applications on both technical and business metrics.

Our team is also striving for such a feature in Container Apps. Our previous APM setup was built on top of Prometheus + Grafana which allowed us to monitor custom metrics with Micrometer and Prometheus. I furthermore noticed, that there already exists a similar integration with AKS. Would it be possible to make this work with Container Apps too?

Our current set of containers already expose these metrics on a generic actuator endpoint (HOST:PORT/actuator/prometheus).

It would be really awesome if Container Apps could automatically forward these metrics to Azure Monitor such that our existing APM use cases could be implemented on Azure too!

I have build a sample on how scrape metrics in Prometheus format using a telegraf sidecar and push them to Azure Managed Prometheus: https://github.com/denniszielke/serverless-job-engine#monitoring-builtin-and-custom-java-metrics-using-micrometer

@SophCarp since you reassigend the issue last week to you, is the container apps team currently actively working on a solution to support container apps metrics via managed prometheus? are there any details that can be shared?
