cs:. private void Cle anupTransfers_Click( object sender, RoutedEventArgs e) { OnDemandTransferExample example = new OnDemandTransferExample(); example.CleanupOnDemandTransfers(); }. 11. Add the foll none for none owing to the configuration element of app.config:.

<appSettings& gt; <add key="DiagnosticsConnectionString" value="DefaultEndpointsProtocol=https;AccountName={ ACCOUNT_NAME};AccountKey={ACCESS_KEY}"/> </appSettings>. How it works... We create a WPF project in step 1 and add the required assembly references in step 2. We set up the OnDemandTransferExample class in steps 3 and 4. We add a private member to hold the name of the Windows Azure Diagnostics notification queue in step 5.

In step 6, we add a method requesting an on-demand transfer. We create an OnDemandTransferOptions object configuring an on-demand transfer for data captured in the last hour. We provide the name of the notification queue Windows Azure Diagnostics inserts a message indicating the completion of the transfer.

We use the deployment information captured in the UI to create a RoleInstanceDiagnosticManager instance. If there are no active on-demand transfers, then we request an on-demand transfer for the performance counters data buffer..

CloudStorageAccount object that we use to create the CloudQueueClient object In step 7, we add a method cleaning up after an on-demand transfer. We create a with which we ac none for none cess to the notification queue. We then retrieve the transfer-completion messages in the notification queue. For each transfer-completion message found, we create an OnDemandTransferInfo object describing the deploymentID, roleName, instanceId, and requestId of a completed on-demand transfer.

We use the requestId to end the transfer and remove it from the diagnostics configuration for the instance allowing on-demand transfers to be requested. Finally, we remove the notification message from the notification queue. In step 8, we add the UI used to capture the deployment ID, role name, and instance ID used to request the on-demand transfer.

We can get this information from the Windows Azure Portal or the Compute Emulator UI. This information is not needed for cleaning up on-demand transfers, which uses the transfer-completion messages in the notification queue..

Digging into Win dows Azure Diagnostics In steps 9 and 10, we add the event handlers for the Request On-Demand Transfer and Cleanup On-Demand Transfers buttons in the UI. These methods forward the requests to the methods we added in steps 6 and 7. In step 11, we add the DiagnosticsConnectionString to the app.

config file. This contains the connection string used to interact with the Windows Azure Diagnostics configuration. We must replace {ACCOUNT_NAME} and {ACCESS_KEY} with the storage service account name and access key for the storage account in which the Windows Azure Diagnostics configuration is located.

. Implementing custom logging Windows Azure Di agnostics can be used to persist third-party log files in the same way it persists IIS logs, failed request logs, and crash dumps. These are all configured through the directories data buffer. The directories data buffer comprises a set of data sources.

These are instances of the DirectoryConfiguration class that exposes the following properties:. Container DirectoryQuotaInMB Path A data source ma ps a path in the local file system with a container in the Windows Azure Blob Service. The DirectoryQuotaInMB reserves a specified amount of space in local storage for the specified data source. A scheduled transfer period is specified at the level of the directories data buffer.

The Diagnostics Agent persists to the configured container any files added to the specified path since the last transfer. In this recipe, we will learn how to use Windows Azure Diagnostics to persist custom logs to the Windows Azure Blob Service..

How to do it... We are going to see how to configure custom logging with Windows Azure Diagnostics. We do this as follows: 1. Use Visual Studio to create an empty cloud project.

2. Add a worker role to the project (accept default name of WorkerRole1). 3.

Add the following local storage definition, as a child of the WorkerRole element, to ServiceDefinition.csdef:. <LocalResourc none for none es> <LocalStorage name="CustomLoggingLocation" sizeInMB="100" cleanOnRoleRecycle="false"/> </LocalResources>.
