Azure Diagnostics 1.3 and later configuration schema

Note

The Azure Diagnostics extension is the component used to collect performance counters and other statistics from:

  • Azure Virtual Machines
  • Virtual Machine Scale Sets
  • Service Fabric
  • Cloud Services
  • Network Security Groups

This page is only relevant if you are using one of these services.

This page is valid for versions 1.3 and newer (Azure SDK 2.4 and newer). Newer configuration sections are commented to show in what version they were added.

The configuration file described here is used to set diagnostic configuration settings when the diagnostics monitor starts.

The extension is used in conjunction with other Microsoft diagnostics products like Azure Monitor, Application Insights, and Log Analytics.

Download the public configuration file schema definition by executing the following PowerShell command:

(Get-AzureServiceAvailableExtension -ExtensionName 'PaaSDiagnostics' -ProviderNamespace 'Microsoft.Azure.Diagnostics').PublicConfigurationSchema | Out-File –Encoding utf8 -FilePath 'C:\temp\WadConfig.xsd'  

For more information about using Azure Diagnostics, see Azure Diagnostics Extension.

Example of the diagnostics configuration file

The following example shows a typical diagnostics configuration file:

Reading this page

The tags following are roughly in order shown in the preceding example. If you don't see a full description where you expect it, search the page for the element or attribute.

Common Attribute Types

scheduledTransferPeriod attribute appears in several elements. It is the interval between scheduled transfers to storage rounded up to the nearest minute. The value is an XML “Duration Data Type.”

DiagnosticsConfiguration Element

Tree: Root - DiagnosticsConfiguration

Added in version 1.3.

The top-level element of the diagnostics configuration file.

Attribute xmlns - The XML namespace for the diagnostics configuration file is:
http://schemas.microsoft.com/ServiceHosting/2010/10/DiagnosticsConfiguration

Child Elements Description
PublicConfig Required. See description elsewhere on this page.
PrivateConfig Optional. See description elsewhere on this page.
IsEnabled Boolean. See description elsewhere on this page.

PublicConfig Element

Tree: Root - DiagnosticsConfiguration - PublicConfig

Describes the public diagnostics configuration.

Child Elements Description
WadCfg Required. See description elsewhere on this page.
StorageAccount The name of the Azure Storage account to store the data in. May also be specified as a parameter when executing the Set-AzureServiceDiagnosticsExtension cmdlet.
StorageType Can be Table, Blob, or TableAndBlob. Table is default. When TableAndBlob is chosen, diagnostic data is written twice -- once to each type.
LocalResourceDirectory The directory on the virtual machine where the Monitoring Agent stores event data. If not, set, the default directory is used:

For a Worker/web role: C:\Resources\<guid>\directory\<guid>.<RoleName.DiagnosticStore\

For a Virtual Machine: C:\WindowsAzure\Logs\Plugins\Microsoft.Azure.Diagnostics.IaaSDiagnostics\<WADVersion>\WAD<WADVersion>

Required attributes are:

- path - The directory on the system to be used by Azure Diagnostics.

- expandEnvironment - Controls whether environment variables are expanded in the path name.

WadCFG Element

Tree: Root - DiagnosticsConfiguration - PublicConfig - WadCFG

Identifies and configures the telemetry data to be collected.

DiagnosticMonitorConfiguration Element

Tree: Root - DiagnosticsConfiguration - PublicConfig - WadCFG - DiagnosticMonitorConfiguration

Required

Attributes Description
overallQuotaInMB The maximum amount of local disk space that may be consumed by the various types of diagnostic data collected by Azure Diagnostics. The default setting is 5120 MB.
useProxyServer Configure Azure Diagnostics to use the proxy server settings as set in IE settings.



Child Elements Description
CrashDumps See description elsewhere on this page.
DiagnosticInfrastructureLogs Enable collection of logs generated by Azure Diagnostics. The diagnostic infrastructure logs are useful for troubleshooting the diagnostics system itself. Optional attributes are:

- scheduledTransferLogLevelFilter - Configures the minimum severity level of the logs collected.

- scheduledTransferPeriod - The interval between scheduled transfers to storage rounded up to the nearest minute. The value is an XML “Duration Data Type.”
Directories See description elsewhere on this page.
EtwProviders See description elsewhere on this page.
Metrics See description elsewhere on this page.
PerformanceCounters See description elsewhere on this page.
WindowsEventLog See description elsewhere on this page.
DockerSources See description elsewhere on this page.

CrashDumps Element

Tree: Root - DiagnosticsConfiguration - PublicConfig - WadCFG - DiagnosticMonitorConfiguration - CrashDumps

Enable the collection of crash dumps.

Attributes Description
containerName Optional. The name of the blob container in your Azure Storage account to be used to store crash dumps.
crashDumpType Optional. Configures Azure Diagnostics to collect mini or full crash dumps.
directoryQuotaPercentage Optional. Configures the percentage of overallQuotaInMB to be reserved for crash dumps on the VM.
Child Elements Description
CrashDumpConfiguration Required. Defines configuration values for each process.

The following attribute is also required:

processName - The name of the process you want Azure Diagnostics to collect a crash dump for.

Directories Element

Tree: Root - DiagnosticsConfiguration - PublicConfig - WadCFG - DiagnosticMonitorConfiguration - Directories

Enables the collection of the contents of a directory, IIS failed access request logs and/or IIS logs.

Optional scheduledTransferPeriod attribute. See explanation earlier.

Child Elements Description
