Explanation:
Step 1: Understand the Requirements
You want to ensure that audit events (such as user actions, project changes, security settings, etc.) from your Azure DevOps organization are logged and available in a Log Analytics workspace in Azure.
This enables centralized monitoring and security compliance.
Step 2: Prerequisites
Before starting, make sure:
* You have an Azure subscription.
* You have permission to create or use a Log Analytics workspace in the Azure portal.
* You are a Project Collection Administrator or Organization Owner in Azure DevOps.
Step 3: Create or Identify a Log Analytics Workspace
* Go to the Azure portal.
* In the search bar, type Log Analytics workspaces and click the service.
* Click + Create to create a new workspace (or select an existing workspace if you have one).
* Provide the following:
* Subscription: your Azure subscription.
* Resource Group: create a new or use an existing one.
* Name: a unique name for the workspace (like DevOpsAuditWorkspace).
* Region: choose the same region as your Azure DevOps organization if possible.
* Click Review + Create, then Create to deploy the workspace.
Step 4: Configure Azure DevOps to Stream Audit Logs
Azure DevOps can stream audit logs to your Log Analytics workspace using the Azure DevOps Audit Stream feature.
* In your browser, go to your Azure DevOps organization:https://dev.azure.com/
{YourOrganizationName}
* In the bottom-left corner, click on the Organization Settings gear icon.
* In the left menu, click on Audit logs.

* Stream type: select Azure Monitor Logs (Log Analytics).
* Azure subscription: select the subscription containing your Log Analytics workspace.
* Resource group: select the resource group.
* Log Analytics workspace: select the workspace created in Step 3.
* Click Save.
Step 5: Validate the Audit Stream Connection
* Go back to the Audit streams page in Azure DevOps to confirm the stream shows as Connected.
* To validate logs:
* In the Azure portal, go to your Log Analytics workspace.
* In the left menu, click on Logs.
* Use the query:
