# Customer intent: As a cloud operator, I want to configure and apply diagnostics extensions to Azure Cloud Services roles, so that I can collect enhanced performance metrics and logs for monitoring and troubleshooting.

# Apply the Microsoft Azure diagnostics extension in Cloud Services (extended support)
> [!IMPORTANT]
> As of March 31, 2025, cloud Services (extended support) is deprecated and will be fully retired on March 31, 2027. [Learn more](https://aka.ms/csesretirement) about this deprecation and [how to migrate](https://aka.ms/cses-retirement-march-2025).
You can monitor key performance metrics for any cloud service. Every cloud service role collects minimal data: CPU usage, network usage, and disk utilization. If the cloud service has the Microsoft.Azure.Diagnostics extension applied to a role, that role can collect more points of data. For more information, see [Extensions Overview](extensions.md)
Microsoft Azure Diagnostics extension can be enabled for Cloud Services (extended support) through [PowerShell](deploy-powershell.md) or [ARM template](deploy-template.md)
## Apply Microsoft Azure Diagnostics extension using PowerShell
```powershell
# Create WAD extension object
$storageAccountKey = Get-AzStorageAccountKey -ResourceGroupName "ContosOrg" -Name "contosostorageaccount"
$configFilePath = "<Insert WAD public configuration file path>"
$wadExtension = New-AzCloudServiceDiagnosticsExtension -Name "WADExtension" -ResourceGroupName "ContosOrg" -CloudServiceName "ContosoCS" -StorageAccountName "contosostorageaccount" -StorageAccountKey $storageAccountKey[0].Value -DiagnosticsConfigurationPath $configFilePath -TypeHandlerVersion "1.5" -AutoUpgradeMinorVersion $true
# Add <privateConfig> settings
$wadExtension.ProtectedSetting = "<Insert WAD Private Configuration as raw string here>"
# Get existing Cloud Service
$cloudService = Get-AzCloudService -ResourceGroup "ContosOrg" -CloudServiceName "ContosoCS"
# Add WAD extension to existing Cloud Service extension object
$cloudService.ExtensionProfile.Extension = $cloudService.ExtensionProfile.Extension + $wadExtension
# Update Cloud Service
$cloudService | Update-AzCloudService
```
Download the public configuration file schema definition by executing the following PowerShell command:
```powershell
(Get-AzureServiceAvailableExtension -ExtensionName 'PaaSDiagnostics' -ProviderNamespace 'Microsoft.Azure.Diagnostics').PublicConfigurationSchema | Out-File -Encoding utf8 -FilePath 'PublicWadConfig.xsd'
```
Here's an example of the public configuration XML file
```
<?xml version="1.0" encoding="utf-8"?>
<PublicConfig xmlns="http://schemas.microsoft.com/ServiceHosting/2010/10/DiagnosticsConfiguration">
<WadCfg>
<DiagnosticMonitorConfiguration overallQuotaInMB="25000">
<PerformanceCounters scheduledTransferPeriod="PT1M">
<PerformanceCounterConfiguration counterSpecifier="\Processor(_Total)\% Processor Time" sampleRate="PT1M" unit="percent" />
<PerformanceCounterConfiguration counterSpecifier="\Memory\Committed Bytes" sampleRate="PT1M" unit="bytes"/>
</PerformanceCounters>
<EtwProviders>
<EtwEventSourceProviderConfiguration provider="SampleEventSourceWriter" scheduledTransferPeriod="PT5M">
<Event id="1" eventDestination="EnumsTable"/>
<DefaultEvents eventDestination="DefaultTable" />
</EtwEventSourceProviderConfiguration>
</EtwProviders>
</DiagnosticMonitorConfiguration>
</WadCfg>
</PublicConfig>
```
Download the private configuration file schema definition by executing the following PowerShell command:
```powershell
(Get-AzureServiceAvailableExtension -ExtensionName 'PaaSDiagnostics' -ProviderNamespace 'Microsoft.Azure.Diagnostics').PrivateConfigurationSchema | Out-File -Encoding utf8 -FilePath 'PrivateWadConfig.xsd'
```
Here's an example of the private configuration XML file
```
<?xml version="1.0" encoding="utf-8"?>
<PrivateConfig xmlns="http://schemas.microsoft.com/ServiceHosting/2010/10/DiagnosticsConfiguration">
<StorageAccount name="string" key="string" />
<AzureMonitorAccount>
<ServicePrincipalMeta>
<PrincipalId>string</PrincipalId>
<Secret>string</Secret>
</ServicePrincipalMeta>
</AzureMonitorAccount>
<SecondaryStorageAccounts>
<StorageAccount name="string" />
</SecondaryStorageAccounts>
<SecondaryEventHubs>
<EventHub Url="string" SharedAccessKeyName="string" SharedAccessKey="string" />
</SecondaryEventHubs>
</PrivateConfig>
```
## Apply Microsoft Azure Diagnostics extension using ARM template
```json
"extensionProfile": {
"extensions": [
{
"name": "Microsoft.Insights.VMDiagnosticsSettings_WebRole1",
"properties": {
"autoUpgradeMinorVersion": true,
"publisher": "Microsoft.Azure.Diagnostics",
"type": "PaaSDiagnostics",
"typeHandlerVersion": "1.5",
"settings": "Include PublicConfig XML as a raw string",
"protectedSettings": "Include PrivateConfig XML as a raw stringβ",
"rolesAppliedTo": [
"WebRole1"
]
}
}
]
},
```
## Next steps
- Review the [deployment prerequisites](deploy-prerequisite.md) for Cloud Services (extended support).
- Review [frequently asked questions](faq.yml) for Cloud Services (extended support).
- Deploy a Cloud Service (extended support) using the [Azure portal](deploy-portal.md), [PowerShell](deploy-powershell.md), [Template](deploy-template.md) or [Visual Studio](deploy-visual-studio.md).
