./Vendor/MSFT/DiagnosticLog/DiagnosticArchive

Root node for archive definition and collection.

The DiagnosticArchive functionality within the DiagnosticLog CSP is used to trigger devices to gather troubleshooting data into a zip archive file and upload that archive to cloud storage.

DiagnosticArchive is designed for ad-hoc troubleshooting scenarios, such as an IT admin investigating an app installation failure using a collection of event log events, registry values, and app or OS log files.

Note

DiagnosticArchive is a "break glass" backstop option for device troubleshooting. Diagnostic data such as log files can grow to many gigabytes. Gathering, transferring, and storing large amounts of data may burden the user's device, the network and cloud storage. Management servers invoking DiagnosticArchive must take care to minimize data gathering frequency and scope.

DiagnosticArchive/ArchiveDefinition

Scope	Editions	Applicable OS
✅ Device ❌ User	✅ Pro ✅ Enterprise ✅ Education ✅ Windows SE ✅ IoT Enterprise / IoT Enterprise LTSC	✅ Windows 10, version 1903 [10.0.18362] and later

./Vendor/MSFT/DiagnosticLog/DiagnosticArchive/ArchiveDefinition

Execute action for this node accepts a Collection XML snippet (as a string) describing what data to gather and where to upload it. The results are zipped and uploaded to the specified SasUrl. The zipped filename format is DiagLogs-{ComputerName}-YYYYMMDDTHHMMSSZ.zip.

With Windows 10 KB5011543 and Windows 11 KB5011563, there is additional support for an extra element that will determine whether the output file generated by the CSP is a flattened folder structure, instead of having individual folders for each directive in the XML. The following example shows a Collection XML:

<Collection>
   <!--NOTE: The value shown here is an example only, for more information see the ID documentation which follows the example -->
   <ID>f1e20cb4-9789-4f6b-8f6a-766989764c6d</ID>
   <!--NOTE: The value shown here is an example only, for more information see the SasUrl documentation which follows the example -->
   <SasUrl><![CDATA[https://myaccount.blob.core.windows.net/mycontainer?sp=aw&st=2020-07-01T23:02:07Z&se=2020-07-02T23:02:07Z&sv=2019-10-10&sr=c&sig=wx9%2FhwrczAI0nZL7zl%2BhfZVfOBvboTAnrGYfjlO%2FRFA%3D]]></SasUrl>
   <RegistryKey>HKLM\Software\Policies</RegistryKey>
   <FoldersFiles>%ProgramData%\Microsoft\DiagnosticLogCSP\Collectors\*.etl</FoldersFiles>
   <Command>%windir%\system32\ipconfig.exe /all</Command>
   <Command>%windir%\system32\mdmdiagnosticstool.exe -out %ProgramData%\temp\</Command>
   <FoldersFiles>%ProgramData%\temp\*.*</FoldersFiles>
   <Events>Application</Events>
   <OutputFileFormat>Flattened</OutputFileFormat>
</Collection>

The XML should include the following elements within the Collection element:

ID: The ID value uniquely identifies this data-gathering request. To avoid accidental repetition of data gathering, the CSP ignores subsequent Set or Execute invocations with the same ID value. The CSP expects the value to be populated when the request is received, so it must be generated by the IT admin or the management server.
SasUrl: The SasUrl value is the target URI to which the CSP uploads the zip file containing the gathered data. It's the responsibility of the management server to provision storage in such a way that the storage server accepts the device's HTTP PUT to this URL. For example, the device management service could:
- Provision cloud storage reachable by the target device, such as a Microsoft Azure blob storage container
- Generate a Shared Access Signature URL granting the possessor (the target device) time-limited write access to the storage container
- Pass this value to the CSP on the target device through the Collection XML as the SasUrl value.

Additionally, the XML may include One or more data gathering directives, which may include any of the following:

RegistryKey: Exports all of the key names and values under a given path (recursive).
- Expected input value: Registry path such as "HKLM\Software\Policies".
- Output format: Creates a .reg file, similar to the output of reg.exe EXPORT command.
- Privacy guardrails: To enable diagnostic log capture while reducing the risk of an IT admin inadvertently capturing user-generated documents, registry paths are restricted to those paths that're under HKLM and HKCR.
Events: Exports all events from the named Windows event log.
- Expected input value: A named event log channel such as "Application" or "Microsoft-Windows-DeviceGuard/Operational".
- Output format: Creates an .evtx file.
Commands: This directive type allows the execution of specific commands such as ipconfig.exe. Note that DiagnosticArchive and the Commands directives aren't a general-purpose scripting platform. These commands are allowed in the DiagnosticArchive context to handle cases where critical device information may not be available through existing log files.
- Expected input value: The full command line including path and any arguments, such as %windir%\\system32\\ipconfig.exe /all.
- Output format: Console text output from the command is captured in a text file and included in the overall output archive. For commands that may generate file output rather than console output, a subsequent FolderFiles directive would be used to capture that output. The example XML above demonstrates this pattern with mdmdiagnosticstool.exe's -out parameter.
- Privacy guardrails: To enable diagnostic data capture while reducing the risk of an IT admin inadvertently capturing user-generated documents, only the following commands are allowed:
  - %windir%\system32\certutil.exe
  - %windir%\system32\dxdiag.exe
  - %windir%\system32\gpresult.exe
  - %windir%\system32\msinfo32.exe
  - %windir%\system32\netsh.exe
  - %windir%\system32\nltest.exe
  - %windir%\system32\ping.exe
  - %windir%\system32\powercfg.exe
  - %windir%\system32\w32tm.exe
  - %windir%\system32\wpr.exe
  - %windir%\system32\dsregcmd.exe
  - %windir%\system32\dispdiag.exe
  - %windir%\system32\ipconfig.exe
  - %windir%\system32\logman.exe
  - %windir%\system32\tracelog.exe
  - %programfiles%\windows defender\mpcmdrun.exe
  - %windir%\system32\MdmDiagnosticsTool.exe
  - %windir%\system32\pnputil.exe
FoldersFiles: Captures log files from a given path (without recursion).
- Expected input value: File path with or without wildcards, such as "%windir%\System32", or "%programfiles%\*.log".
- Privacy guardrails: To enable diagnostic log capture while reducing the risk of an IT admin inadvertently capturing user-generated documents, only paths under the following roots are allowed:
  - %PROGRAMFILES%
  - %PROGRAMDATA%
  - %PUBLIC%
  - %WINDIR%
  - %TEMP%
  - %TMP%
- Additionally, only files with the following extensions are captured:
  - .log
  - .txt
  - .dmp
  - .cab
  - .zip
  - .xml
  - .html
  - .evtx
  - .etl
OutputFileFormat: Flattens folder structure, instead of having individual folders for each directive in the XML.
- The value "Flattened" is the only supported value for the OutputFileFormat. If the OutputFileFormat is absent in the XML, or if explicitly set to something other than Flattened, it will leave the file structure in old structure.

./Vendor/MSFT/DiagnosticLog/EtwLog/Channels

Root node of registered "Channel" nodes.

The type of event tracing exports event data from a specific channel. Users can add or delete a channel node using the full name, such as Microsoft-Windows-AppModel-Runtime/Admin.

The DiagnosticLog CSP maintains a log file for each channel node and the log file is overwritten if a start command is triggered again on the same channel node.

For each channel node, the user can:

Export channel event data into a log file (.evtx).
Enable or disable the channel from Event Log service to allow or disallow event data being written into the channel.
Specify an XPath query to filter events while exporting the channel event data.

./Vendor/MSFT/DiagnosticLog/EtwLog/Collectors

Root node of registered "Collector" nodes.

This type of event tracing collects event data from a collection of registered ETW providers. An event collector is a container of registered ETW providers. Users can add or delete a collector node and register or unregister multiple providers in this collector.

The {CollectorName} must be unique within the CSP and must not be a valid event channel name or a provider GUID.

The DiagnosticLog CSP maintains a log file for each collector node and the log file is overwritten if a start command is triggered again on the same collector node.

For each collector node, the user can:

Start or stop the session with all registered and enabled providers.
Query session status.
Change trace log file mode.
Change trace log file size limit.

The configurations log file mode and log file size limit don't take effect while trace session is in progress. These attributes are applied when user stops the current session and then starts it again for this collector.

For each registered provider in this collector, the user can:

Specify keywords to filter events from this provider.
Change trace level to filter events from this provider.
Enable or disable the provider in the trace session.

The changes on State, Keywords, and TraceLevel takes effect immediately while trace session is in progress.

Note

Microsoft-WindowsPhone-Enterprise-Diagnostics-Provider (GUID - 3da494e4-0fe2-415C-b895-fb5265c5c83b) has the required debug resource files built into Windows, which will allow the logs files to be decoded on the remote machine. Any other logs may not have the debug resources required to decode.

Description framework properties:

Property name	Property value
Format	`node`
Access Type	Get

Example:

To gather diagnostics using this CSP:

Specify a CollectorName for the container of the target ETW providers.
(Optional) Set logging and log file parameters using the following options:
- TraceLogFileMode
- LogFileSizeLimitMB
Indicate one or more target ETW providers by supplying its ProviderGUID to the Add operation of EtwLog/Collectors/CollectorName/Providers/ProviderGUID.
(Optional) Set logging and log file parameters using the following options:
- TraceLevel
- Keywords
Start logging using TraceControl EXECUTE command "START".
Perform actions on the target device that will generate activity in the log files.
Stop logging using TraceControl EXECUTE command "STOP".
Collect the log file located in the %temp% folder using the Reading a log file method described in FileDownload.

./Vendor/MSFT/DiagnosticLog/EtwLog/Collectors/{CollectorName}

Each dynamic node represents a registered 'Collector' node. CSP will maintain an ETW trace session for this collector with its name used as a unique identifier. In a collector, a valid ETW provider can be registered and unregistered. The collector's associated trace session will enable the registered providers in it if the provider's state is 'Enabled'. Each provider's state, trace level and keywords can be controlled separately. The name of this node mustn't be a valid Windows event channel name. It can be a etw provider guid as long as it isn't equal to an already registered 'Provider' node name.

./Vendor/MSFT/DiagnosticLog/FileDownload

Root node of all csp nodes that are related to log file download in csp.

The FileDownload feature of the DiagnosticLog CSP enables a management server to pull data directly from the device. In the FileDownload context, the client and server roles are conceptually reversed, with the management server acting as a client to download the data from the managed device.

Reading a log file:

Enumerate log file under ./Vendor/MSFT/DiagnosticLog/FileDownload/DMChannel.
Select a log file in the Enumeration result.
Set BlockSizeKB per DM server payload limitation.
Get BlockCount to determine total read request.
Set BlockIndexToRead to initialize read start point.
Get BlockData for upload log block.
Increase BlockIndexToRead.
Repeat steps 5 to 7 until BlockIndexToRead == (BlockIndexToRead – 1).

./Vendor/MSFT/DiagnosticLog/Policy/Channels/{ChannelName}/ActionWhenFull

Action to take when the log file reaches maximum size. "Truncate", "Overwrite", "Archive".

If you disable or don't configure this policy setting, the locally configured value will be used as default. Every channel that is installed, whether inbox or by ISVs, is responsible for defining its own local configuration, and that configuration can be changed by any administrator. Values set via this policy override but don't replace local configuration.

Description framework properties:

Property name	Property value
Format	`chr` (string)
Access Type	Add, Delete, Get, Replace

Allowed values:

Value	Description
Truncate	When the log file reaches its maximum file size, new events aren't written to the log and are lost.
Overwrite	When the log file reaches its maximum file size, new events overwrite old events.
Archive	When the log file reaches its maximum size, the log file is saved to the location specified by the "Archive Location" policy setting. If archive location value isn't set, the new file is saved in the same directory as current log file.

Comparing FileDownload and DiagnosticArchive

Both the FileDownload and DiagnosticArchive features can be used to get data from the device to the management server, but they're optimized for different workflows.

FileDownload enables the management server to directly pull byte-level trace data from the managed device. The data transfer takes place through the existing OMA-DM/SyncML context. It's used together with the EtwLogs feature as part of an advanced monitoring or diagnostic flow. FileDownlod requires granular orchestration by the management server, but avoids the need for dedicated cloud storage.
DiagnosticArchive allows the management server to give the CSP a full set of instructions as single command. Based on those instructions, the CSP orchestrates the work client-side to package the requested diagnostic files into a zip archive and upload that archive to cloud storage. The data transfer happens outside of the OMA-DM session, via an HTTP PUT.

How to review ArchiveResults

The zip archive that is created and uploaded by ArchiveResults contains a folder structure like the following example:

PS C:\> dir C:\DiagArchiveExamples\DiagLogs-MYDEVICE-20201202T182748Z

    Directory: C:\DiagArchiveExamples\DiagLogs-MYDEVICE-20201202T182748Z

Mode                 LastWriteTime         Length Name
----                 -------------         ------ ----
la---            1/4/2021  2:45 PM                1
la---            1/4/2021  2:45 PM                2
la---           12/2/2020  6:27 PM           2701 results.xml

Each data gathering directive from the original Collection XML corresponds to a folder in the output. For example, the first directive was:

<Collection HRESULT="0">
     <RegistryKey HRESULT="0">HKLM\Software\Policies</RegistryKey>
</Collection>

Then, folder 1 will contain the corresponding export.reg file.

The results.xml file is the authoritative map to the output. It includes a status code for each directive. The order of the directives in the file corresponds to the order of the output folders. Using results.xml the administrator can see what data was gathered, what failures may have occurred, and which folders contain which output. For example, the following results.xml content indicates that registry export of HKLM\Software\Policies was successful and the data can be found in folder 1. It also indicates that netsh.exe wlan show profiles command failed.

<Collection HRESULT="0">
    <ID>268b3056-8c15-47c6-a1bd-4bc257aef7b2</ID>
    <RegistryKey HRESULT="0">HKLM\Software\Policies</RegistryKey>
    <Command HRESULT="-2147024895">%windir%\system32\netsh.exe wlan show profiles</Command>
</Collection>

Administrators can apply automation to 'results.xml' to create their own preferred views of the data. For example, the following PowerShell one-liner extracts from the XML an ordered list of the directives with status code and details.

Select-XML -Path results.xml -XPath '//RegistryKey | //Command | //Events | //FoldersFiles' | Foreach-Object -Begin {$i=1} -Process { [pscustomobject]@{DirectiveNumber=$i; DirectiveHRESULT=$_.Node.HRESULT; DirectiveInput=$_.Node.('#text')} ; $i++}

This example produces output similar to the following output:

DirectiveNumber DirectiveHRESULT DirectiveInput
--------------- ---------------- --------------
              1 0                HKLM\Software\Policies
              2 0                HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall
              3 0                HKLM\Software\Microsoft\IntuneManagementExtension
              4 0                HKLM\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall
              5 0                %windir%\system32\ipconfig.exe /all
              6 0                %windir%\system32\netsh.exe advfirewall show allprofiles
              7 0                %windir%\system32\netsh.exe advfirewall show global
              8 -2147024895      %windir%\system32\netsh.exe wlan show profiles

The next example extracts the zip archive into a customized flattened file structure. Each file name includes the directive number, HRESULT, and so on. This example could be customized to make different choices about what information to include in the file names and what formatting choices to make for special characters.
