# Azure Storage
## Quick start

Instrumentation can be enabled for Azure Storage by referencing [`Elastic.Apm.Azure.Storage`](https://www.nuget.org/packages/Elastic.Apm.Azure.Storage) package and subscribing to diagnostic events using one of the subscribers:
- If the agent is included by referencing the `Elastic.Apm.NetCoreAll` package, the subscribers will be automatically subscribed with the agent, and no further action is required.
- If you’re using `Azure.Storage.Blobs`, subscribe `AzureBlobStorageDiagnosticsSubscriber` with the agent
  ```csharp
  Agent.Subscribe(new AzureBlobStorageDiagnosticsSubscriber());
  ```
- If you’re using `Azure.Storage.Queues`, subscribe `AzureQueueStorageDiagnosticsSubscriber` with the agent
  ```csharp
  Agent.Subscribe(new AzureQueueStorageDiagnosticsSubscriber());
  ```
- If you’re using `Azure.Storage.Files.Shares`, subscribe `AzureFileShareStorageDiagnosticsSubscriber` with the agent
  ```csharp
  Agent.Subscribe(new AzureFileShareStorageDiagnosticsSubscriber());
  ```

For Azure Queue storage,
- A new transaction is created when one or more messages are received from a queue
- A new span is created when there is a current transaction, and when a message is sent to a queue

For Azure Blob storage, a new span is created when there is a current transaction and when a request is made to blob storage.
For Azure File Share storage, a new span is crated when there is a current transaction and when a request is made to file storage.
