The built-in role [Monitoring Reader](https://learn.microsoft.com/en-us/azure/azure-monitor/roles-permissions-security#monitoring-reader) is sufficient to access the required Azure Service Bus metrics.
 3. Execute `az account set --subscription {SubscriptionId}`, where `{SubscriptionId}` is a Guid matching the subscription id that contains the Azure Service Bus namespace.
 
 Completing these steps stores credentials that can be used by the tool.

 ## What the tool does
 
-First, the tool uses a `ServiceBusAdministrationClient` to [query the queue names](https://learn.microsoft.com/en-us/dotnet/api/azure.messaging.servicebus.administration.servicebusadministrationclient.getqueueasync?view=azure-dotnet) from the namespace. Next, a `MetricsQueryClient` is used to [query for `CompleteMessage` metrics](https://learn.microsoft.com/en-us/dotnet/api/azure.monitor.query.metricsqueryclient.queryresourceasync?view=azure-dotnet) for the past 30 days from each queue.
