Enterprise Library V6 Logging with Azure SDK 2.8 and Azure Diagnostics 1.3

Posted on by

In a previous post I wrote about configuring the Enterprise Library V6 to work with Azure Diagnostics. There have been significant changes (detailed in this very helpful post) to the way the Azure Diagnostics infrastructure works for Azure SDK Versions 2.4/2.5. If the diagnostics infrastructure is not properly configured there will be no WADLogs tables created and/or trace information logged.

The following steps provision diagnostics for a Azure web role or worker role. This “cheat sheet” assumes you already have the Azure Service Management Cmdlets installed.

Add-AzureAccount – This will prompt for Azure credentials

Get-AzureSubscription –Display details about your subscription(s)

SubscriptionId : 15daec19-f6e9-403c-8652-1234567890123
SubscriptionName : MyCompany
Environment : AzureCloud
DefaultAccount : me@mycompany.co.nz
IsDefault : False
IsCurrent : False
TenantId : e07af3b3-10c2-49a5-97cc-123456789012
CurrentStorageAccountName :
SubscriptionId : eba7ed1c-5503-4349-bcc7-123456789012
SubscriptionName : YourCompany
Environment : AzureCloud
DefaultAccount : you@yourcompany.co.nz
IsDefault : True
IsCurrent : True
TenantId : e07af3b3-10c2-49a5-97cc-1234567890
CurrentStorageAccountName :
…

If you have more than one Azure subscription you will need to select the one you want to use.

Select-AzureSubscription -Current -SubscriptionName “MyCompany” (beware names are case sensitive)

Get-AzureService – Displays a list of your Azure services

Get-AzureRole -ServiceName “myDemoApp”

RoleName : WebRole
InstanceCount : 1
DeploymentID : cb4e439907774090be8d123456789012
ServiceName : myDemoApp
OperationDescription : Get-AzureRole

I then modified the role diagnostics config file (diagnostics.wadcfgx) by removing

<DiagnosticsConfiguration xmlns=”http://schemas.microsoft.com/ServiceHosting/2010/10/DiagnosticsConfiguration”&gt;
+
</DiagnosticMonitorConfiguration>

+

<PrivateConfig xmlns=”http://schemas.microsoft.com/ServiceHosting/2010/10/DiagnosticsConfiguration”&gt;
<StorageAccount endpoint=”” />
</PrivateConfig>
<IsEnabled>true</IsEnabled> – Not certain about this

I then uploaded it with the following powershell script
$storage_name = “entlib”
$key = “Storage key goes here==”
$config_path=”C:\..\diagnostics.xml”
$service_name=”myDemoApp”
$storageContext = New-AzureStorageContext -StorageAccountName $storage_name -StorageAccountKey $key
Set-AzureServiceDiagnosticsExtension -StorageContext $storageContext -DiagnosticsConfigurationPath $config_path -ServiceName $service_name -Slot Production -Role WebRole

Repeat for WorkerRole and WebRole
