Collect diagnostic logs for Azure Stack HCI

Artikkel
03/25/2024

Applies to: Azure Stack HCI, version 23H2

This article describes how to collect diagnostic logs and send them to Microsoft to help identify and fix any issues with your Azure Stack HCI solution.

On-demand log collection

On-demand log collection involves manually collecting and sending diagnostic logs to Microsoft using the Send-DiagnosticData cmdlet from any node within the Azure Stack HCI cluster. When you run this cmdlet, the logs are temporarily copied locally. This copy is parsed, sent to Microsoft, and then deleted from your system. Microsoft retains this diagnostic data for up to 30 days and handles it as per the standard privacy practices.

When to use on-demand log collection

Here are the scenarios in which you can perform on-demand log collection:

Microsoft Support requests for logs based on an open case.
Logs are collected when a cluster is connected and registered.
Logs are collected when the Observability components are operational and installed.
Logs are collected when a cluster is only partly registered.
Logs are collected for issues not related to registration failures.

To explore additional log collection methods in Azure Stack HCI and understand when to use them, see Diagnostics.

Prerequisites

Before you collect on-demand logs, you must complete the following prerequisites:

You must have access to an Azure Stack HCI cluster.
You must have access to Azure.
You must have installed the AzureEdgeTelemetryAndDiagnostics extension to collect telemetry and diagnostics information from your Azure Stack HCI system. For information about the extension, see Azure Stack HCI telemetry and diagnostics extension overview.

Perform on-demand log collection via PowerShell

You can perform on-demand log collection using PowerShell, the recommended method, or Windows Admin Center in the Azure portal, as described later in this article.

Run the Send-DiagnosticData cmdlet from any node on your Azure Stack HCI cluster to perform on-demand log collection.

Here are some important points to consider:

The completion time of the Send-DiagnosticData cmdlet varies depending on factors, such as the roles for which logs are being collected, time duration specified, and the number of nodes in your Azure Stack HCI environment.
If you don't specify any parameters, the Send-DiagnosticData cmdlet collects data from all nodes for the previous one-hour duration.

Here's the syntax of Send-DiagnosticData:

Send-DiagnosticData [[-FilterByRole] <string[]>] [[-FromDate] <datetime>] [[-ToDate] <datetime>] [[-CollectSddc] <bool>] [<CommonParameters>]

For reference information on Send-DiagnosticData, see the Send-DiagnosticData command reference section later in this article.

Examples and sample outputs

Here are some example commands with sample outputs that show how to use the Send-DiagnosticData cmdlet with different parameters.

Send diagnostics data with date filtering

In this example, you send diagnostics data with date filtering for log files for the past two hours:

Send-DiagnosticData -FromDate (Get-Date).AddHours(-2) -ToDate (Get-Date)

Here's a sample output of this command:

PS C:\CloudDeployment\logs> Send-DiagnosticData -FromDate (Get-Date).AddHours(-2) -ToDate (Get-Date)
Converting FromDate and ToDate to UTC
FromDate in UTC is now 12/04/2023 19:14:18. ToDate in UTC is now 12/04/2023 21:14:18
The correlation Id is <Correlation-ID>. This is used to query for this log collection in the diagnostic pipeline.
Provide the below information to the customer support engineer working on your case.

Send diagnostic data for specified roles

In this example, you send diagnostic data with role filtering for BareMetal and ECE:

Send-DiagnosticData -FilterByRole BareMetal, ECE –CollectSddc $false

Here's a sample output of this command:

PS C:\Users\docsuser> Send-DiagnosticData -FilterByRole BareMetal, ECE –CollectSddc $false
FromDate parameter not specified. Setting to default value 12/04/2023 20:41:21

Get a history of log collection

You can get a history of all the log collections that you have performed. This history helps you learn about the kinds of log collections, the sizes of log collections, the times when logs were collected, and the methods of log collection.

To get a history of log collections for the last 90 days, enter:

Get-LogCollectionHistory

Here's a sample output of the Get-LogCollectionHistory cmdlet. Note that the datetime parameters are in the UTC timezone.

PS C:\CloudDeployment\logs> Get-LogCollectionHistory

You can store diagnostic logs on a local Server Message Block (SMB) share if you have network issues or prefer to save data locally instead of sending it to Azure.

Follow these steps to save logs to a local share:

Run the following command to create a share:

New-SMBShare -Name <share-name> -Path <path-to-share> -FullAccess Users -ChangeAccess 'Server Operators'

Run the following commands to create PSCredentials to the share:

$user = "<username>"
$pass = "<password>"
$sec=ConvertTo-SecureString -String $pass -AsPlainText -Force
$shareCredential = New-Object System.Management.Automation.PSCredential ($user, $sec)

Run the following command on each node of the cluster to collect logs and save them locally:
```
Send-DiagnosticData -SaveToPath <path to share> -ShareCredential $shareCredential
```

If you have outbound connectivity from the SMB share where you saved the logs, you can run the following command to send the logs to Microsoft:

Send-DiagnosticData NoLogCollection -SupplementaryLogs <path-to-share> -ShareCredentail $shareCredential

Provide required information in a support case

If you encounter an issue and need help from Microsoft Support, they might ask for specific information to locate your logs.

You can obtain this information from either the output of the Send-DiagnosticData cmdlet or directly from the problematic page in the Azure portal.

Provide information from the `Send-DiagnosticData` output

When you use Send-DiagnosticData to collect logs, it also provides key details in its output that you need to share with Microsoft Support. After you collect logs, they're sent to the Kusto database. Microsoft Support can then use the information provided to locate your logs in Kusto and help you in resolving the reported issue.

When requested, share the following information with Microsoft Support. Get this information from the Send-DiagnosticData output.

AEORegion: The location where your device is registered.
AEODeviceARMResourceUri: A unique identifier to locate the resource, for example: /subscriptions/<subscription GUID>/resourceGroups/<Name of Resource group>/providers/Microsoft.AzureStackHCI/clusters/<Name of Cluster>.
AEOClusterNodeArcResourceUri: A unique identifier to locate the ARC resource, for example: /subscriptions/<subscription GUID>/resourceGroups/<Name of Resource group>/providers/Microsoft.HybridCompute/Machines/<machine name>.
CorrelationId: A unique identifier to locate the logs.

Provide information from the Azure portal page where issue occurs

On the problematic page in the Azure portal, press CTRL+ALT+A to download a diagnostic file with the following information: session ID and the URL. In most cases, this information is sufficient to get Microsoft Support started on troubleshooting.

If you're on any of the Azure Stack HCI blades where you're experiencing issues, the current URI has the resource ID needed to debug the service.

`Send-DiagnosticData` command reference

This section provides reference information on Send-DiagnosticData, including its parameters, syntax, and usage examples.

FromDate and ToDate

These parameters enable you to collect logs for a specific time period.

Syntax

Send-DiagnosticData [[-FilterByRole] <string[]>] [[-FromDate] <datetime>] [[-ToDate] <datetime>] [[-CollectSddc] <bool>]  [<CommonParameters>]

Example

$fromDate = Get-Date -Date "11/30/2023 18:35:00"
$toDate = Get-Date -Date "11/30/2023 19:35:00"
Send-DiagnosticData –FromDate $fromDate –ToDate $toDate

Extension version

All

FilterByRole

This parameter lets you choose which roles’ logs you want to collect. You can specify multiple roles. For a list of available roles on which you can filter logs, see Roles available for filtering logs.

Syntax

Send-DiagnosticData [[-FilterByRole] <string[]>]

Example

Send-DiagnosticData –FilterByRole “ALM” -CollectSddc $false

Extension version

All

CollectSddc

Determines whether to include or exclude software-defined data center (SDDC) logs. By default, SDDC logs are included. Set it to $false if you want to exclude them. For more information about using SDDC diagnostic tools, see Collect diagnostic data for clusters.

Syntax

Send-DiagnosticData [-CollectSddc <bool>]

Example

Send-DiagnosticData –CollectSddc $false

Extension version

All

BypassObsAgent

When bypassing the observability agent, logs are collected only on the node where the log collection was initiated. No record of the collection is kept in the history.

Syntax

Send-DiagnosticData [-BypassObsAgent]

Example

Send-DiagnosticData –BypassObsAgent

Extension version

All

SaveToPath

This parameter allows you to save the diagnostic logs to a specified path on the host machine, rather than transmitting them to Microsoft.

Syntax

Send-DiagnosticData -SaveToPath <string> [-FilterByRole <string[]>] [-FromDate <datetime>] [-ToDate <datetime>] [-CollectSddc <bool>] [-SupplementaryLogs <string>] [-ShareCredential <pscredential>] [-BypassObsAgent]  [<CommonParameters>]

Examples

You can provide either a share path or an output path on the host to the SaveToPath parameter.

Send-DiagnosticData –SaveToPath <output path>

Send-DiagnosticData –SaveToPath <share path>

If you’re using a share path that is not mapped, you must also use the -ShareCredential parameter.

Send-DiagnosticData –SaveToPath <share path> -ShareCredential <credentials for share path>

You can use SaveToPath with other parameters, such as FilterByRole, FromDate, ToDate, CollectSddc, SupplementaryLogs, ShareCredential, and BypassObsAgent.

Send-DiagnosticData –SaveToPath <output path> -FIlterByRole <role>

Extension version

Versions 1.0.2.0 and above

NoLogCollection

The NoLogCollection switch parameter allows you to send an ad-hoc set of logs to Microsoft. When using this parameter, consider the following details:

You can combine the SupplementaryLogs, ShareCredential, and BypassObsAgent parameters with the NoLogCollection parameter.
The SupplementaryLogs parameter is mandatory when using NoLogCollection. It specifies the path to the logs that need to be sent to Microsoft.
You have the flexibility to pass either a share path or an output path on the host to the SupplementaryLogs parameter. If you’re using an unmapped share path, you must also use the -ShareCredential parameter.

Syntax

Send-DiagnosticData -SupplementaryLogs <string> -NoLogCollection [-ShareCredential <pscredential>] [-BypassObsAgent]  [<CommonParameters>]

Examples

Use –NoLogCollection with the mandatory SupplementaryLogs parameter:

Send-DiagnosticData –NoLogCollection –SupplementaryPath <output path>

Use –NoLogCollection with unmapped share path:

Send-DiagnosticData –NoLogCollection –SupplementaryPath <share path>
-ShareCredential <credential to share path>

Extension version

Versions 1.0.2.0 and above

SupplementaryLogs

The SupplementaryLogs parameter allows you to send ad-hoc logs to Microsoft.

Syntax

You can use it in the following ways:

With SaveToPath. In this scenario, both diagnostic logs and ad-hoc logs are collected and saved to a specified path.

Send-DiagnosticData [-SupplementaryLogs <string>] -SaveToPath <path>

With NoLogCollection. Here, only ad-hoc logs are collected and sent to Microsoft. No diagnostic logs are collected.

Send-DiagnosticData -SupplementaryLogs <string> -NoLogCollection

Without SaveToPath or NoLogCollection. This means that both diagnostic logs and ad-hoc logs are collected and sent to Microsoft.

Send-DiagnosticData [-SupplementaryLogs <string>]

When collecting both diagnostic and ad-hoc logs, you can use the SupplementaryLogs parameter with other parameters such as FilterByRole, FromDate, ToDate, and CollectSddc.

Examples

Without SaveToPath or NoLogCollection:

Send-DiagnosticData –SupplementaryLogs <path to adhoc logs to collect>

With SaveToPath:

Send-DiagnosticData –SaveToPath <path> -SupplementaryLogs <path to adhoc logs to collect>

With NoLogCollection:

Send-DiagnosticData –NoLogCollection –SupplemenatryLogs <path to adhoc logs to collect>

Extension version

Versions 1.0.2.0 and above

ShareCredential

This parameter provides the flexibility to either collect logs and save them to a share path or directly send logs from a share path to Microsoft.

Syntax

Save logs to a path:

Send-DiagnosticData [-ShareCredential <pscredential>] -SaveToPath <path>

Send logs on a share path to Microsoft:

Send-DiagnosticData [-ShareCredential <pscredential>] -SupplementaryLogs <path> -NoLogCollection;

Examples

Save logs to a path:

Send-DiagnosticData –SaveToPath <share path> -ShareCredential <credential to share path>

Send logs on a share path to Microsoft:

Send-DiagnosticData –NoLogCollection –SupplementaryLogs <share path> –ShareCredential <credential to the share path>

Extension version

All

(Plan to deprecate) ToSMBShare

This parameter allows you to save logs either to an output path or a share path. If you were using a share path that wasn't mapped, you needed to use the ShareCredential parameter as well. Since this parameter will be removed in future versions of the extension, use the -SaveToPath parameter instead.

Syntax

Send-DiagnosticData –ToSMBShare –SharePath <path> [-ShareCredential <pscredential>]

Examples

Save logs to an output path or share path:

Send-DiagnosticData –ToSMBShare –SharePath <output path or share path>

Save logs to a share path that's not mapped:

Send-DiagnosticData –ToSMBShare –SharePath <share path> -ShareCredential <credential for the share path>

Extension version

Initially accessible across all versions, however, this parameter will eventually be limited to Versions 0.1.42 and earlier.

(Plan to deprecate) FromSMBShare

This parameter allows you to send logs from an output path or share path directly to Microsoft. If you were using a share path that wasn't mapped, you needed to use the ShareCredential parameter as well. Since this parameter will be removed in future versions of the extension, use the -NoLogCollection parameter instead.

Syntax

Send-DiagnosticData –FromSMBShare –SharePath <path> [-ShareCredential <pscredential>]

Examples

Send-DiagnosticData –FromSMBShare –SharePath <output path or share path>

Send-DiagnosticData –FromSMBShare –SharePath <share path>

Extension version

Initially accessible across all versions, however, this parameter will eventually be limited to Versions 0.1.42 and earlier.

(Plan to deprecate) SharePath

The SharePath parameter can be used for one of the following purposes:

Save diagnostic logs to a share path or output path.
Send logs to Microsoft from a share path or output path. If you're using a share path and the share path is not mapped, then the ShareCredential parameter must also be used.

Since this parameter will be removed in future versions of the extension, use the –SaveToPath to save logs to a path, or –SupplementaryLogs when sending ad-hoc logs to Microsoft instead.

Syntax

Send-DiagnosticData –ToSMBShare –SharePath <path> [-ShareCredential <pscredential>];

Send-DiagnosticData –FromSMBShare –SharePath <path> [-ShareCredential <pscredential>];

Examples

Send-DiagnosticData –ToSMBShare –SharePath <output path or share path>

Send-DiagnosticData –ToSMBShare –SharePath <share path> -ShareCredential <credential for the share path>

Send-DiagnosticData –FromSMBShare –SharePath <output path or share path>

Send-DiagnosticData –FromSMBShare –SharePath <share path>

Extension version

Initially accessible across all versions, however, this parameter will eventually be limited to Versions 0.1.42 and earlier.
