To use PowerShell for log collection, run the Send-DiagnosticData
cmdlet from any node within the Azure Local instance. This cmdlet temporarily copies the logs locally. The copied logs are parsed, sent to Microsoft, and then deleted from your system.
Here are some important points to consider when collecting logs using PowerShell:
- The completion time of the
Send-DiagnosticData
cmdlet varies depending on factors, such as the roles for which logs are being collected, the time duration specified, and the number of nodes in your Azure Local 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.

Save logs to a local file share
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 system 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
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.

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 systems.
Syntax
Send-DiagnosticData [-CollectSddc <bool>]
Example
Send-DiagnosticData –CollectSddc $false
Extension version
All

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 isn't 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 –SupplementaryLogs <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 isn't 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.
