When you power down your VMs in Azure, the Datadog Azure integration still collects the metric azure.vm.status for that VM. This metric is tagged with status:running, status:not_running, or status:unknown.

This is intended, but causes the VM to remain on your infrastructure list. If your VM reports only this metric, it does not count towards your billable host-count. See the Datadog Billing section for more info on billing matters.

If you destroy your Azure VM, it phases out of your infrastructure list within 3 hours.
