This can be incorporated into the template that deploys the VM itself, too.

@description('Workspace ID of the log analytics workspace to which these VMs are to be onboarded.')
param logAWId string

@description('Workspace key of the log analytics workspace to which these VMs are to be onboarded.')
@secure()
param logAWKey string

var vmArray = split(targetVMs, ',')
