Unable to find log analytics workspace key

Question

Unable to find log analytics workspace key

Mike 25

The Logic App send data action requires the Log Analytics workspace key. Workspace keys are no longer visible in the Azure portal. I found this information, The “Primary Key” and “Secondary Key” fields were part of the older Log Analytics Agent (MMA) configuration model. With the introduction of the Azure Monitor Agent (AMA), the authentication mechanism has changed: but it doesn't address what to do in this case.

I tried using the Get-AzOperationalInsightWorkspaceSharedKeys command in Cloud Shell, but it failed stating that it couldn't find the Resource Group, even though I used the same Resource Group name that was returned with the command Get-AZOperationalInsightsWorkspace.

Any suggestions?

The AI agent suggested using the command Update-AzOperationalInsightsWOrkspaceSharedKey to regenerate the keys. That command resulted in the following error.

Update-AzOperationalInsightsWorkspaceSharedKey: HTTP Status Code: BadRequest

Error Message: keyType value must equal primarySharedKey or secondarySharedKey. Operation Id: 'a7f24848fe97cf6f3631c1836eb12c49'

Hi Mike,

Thanks for reaching out to Microsoft Q&A.

You can use below command to fetch Log Analytics workspace keys using azure cli:

az monitor log-analytics workspace get-shared-keys --resource-group <ResourceGroup> --workspace-name <loganalyticsname> --query "{primaryKey: primarySharedKey, secondaryKey: secondarySharedKey}"

I tried the same and able to fetch both Primary Key and Secondary Key of log analytics workspace as below:

Hope it helps!

Thank you, Pravallika KV. I expect that will work. I'm getting a different error that the Resource Group name is not being recognized (Resource group 'xxxx' could not be found, despite the fact that the same Resource Group name is returned by the command 'Get-AzOperationalInsightsWorkspace.'

Hi Mike,

The error Resource group 'xxxx' could not be found usually happens when the context or subscription in your PowerShell session is not the one where the resource group exists, even if Get-AzOperationalInsightsWorkspace returns it.

Check below steps:

Verify the current subscription

Get-AzContext

Make sure the Subscription matches the subscription where the resource group actually exists, if it doesn't, switch to the correct subscription:

Set-AzContext -Subscription "Your-Subscription-Name-or-ID"

Azure resource group names are case-insensitive, but sometimes extra spaces or invisible characters i.e., copy-paste can cause issues. Ensure you are using exactly the same name.

Sometimes there may be a workspace with the same name in another subscription, so specify both resource group and subscription:

Get-AzOperationalInsightsWorkspace -ResourceGroupName "xxxx" -Name "workspace-name"

If using Update-AzOperationalInsightsWorkspaceSharedKey, make sure your PowerShell session is using the same subscription and context as the one returned by Get-AzOperationalInsightsWorkspace.

Example:

Set-AzContext -Subscription "Your-Subscription-ID" Update-AzOperationalInsightsWorkspaceSharedKey -ResourceGroupName "xxxx" -Name "YourWorkspaceName"

Thank you. I was aware of that and first verified that I was in the correct context.
