 You should create an Azure resource where the Azure Monitor metrics will be published to. For our sample, we created a VMSS (Virtual Machine Scaleset resource) with 0 Virtual Machines (so there is no compute charge) but a single VM in the deallocated state could also work. Once you do that, you should copy the resource ID and add it to the telegraf.conf file.
