Monitor Azure Functions on Consumption Plans
Azure Functions let you run code without provisioning or managing servers. This deployment model is sometimes referred to as "serverless" or "Function as a Service" (FaaS).
An Azure Function runs in an application on a container managed by Azure. This lets you focus on writing code without worrying about the underlying application or infrastructure.
Azure Functions are ephemeral. This means that the underlying container can be suspended or recycled when there’s no request pending.
For Azure Functions, monitoring consumption is based on Davis data units. See Serverless monitoring for details.
