Monitor service provider activity
Customers who have delegated subscriptions for Azure Lighthouse can view Azure Activity log data to see all actions taken. This gives customers full visibility into operations that service providers are performing, along with operations done by users within the customer's own Azure Active Directory (Azure AD) tenant.
View activity log data
You can view the activity log from the Monitor menu in the Azure portal. To limit results to a specific subscription, use the filters to select a specific subscription. You can also view and retrieve activity log events programmatically.
Users in a service provider's tenant can view activity log results for a delegated subscription in a customer tenant if they were granted the Reader role (or another built-in role which includes Reader access) when that subscription was onboarded to Azure Lighthouse.
In the activity log, you'll see the name of the operation and its status, along with the date and time it was performed. The Event initiated by column shows which user performed the operation, whether it was a user in a service provider's tenant acting through Azure Lighthouse, or a user in the customer's own tenant. Note that the name of the user is shown, rather than the tenant or the role that the user has been assigned for that subscription.
Users from the service provider appear in the activity log, but these users and their role assignments aren't shown in Access Control (IAM) or when retrieving role assignment info via APIs.
Logged activity is available in the Azure portal for the past 90 days. You can also store this data for a longer period if needed.
Set alerts for critical operations
To stay aware of critical operations that service providers (or users in your own tenant) are performing, we recommend creating activity log alerts. For example, you may want to track all administrative actions for a subscription, or be notified when any virtual machine in a particular resource group is deleted. When you create alerts, they'll include actions performed by users in the customer's own tenant as well as in any managing tenants.
For more information, see Create, view, and manage activity log alerts.
Create log queries
Log queries can help you analyze your logged activity or focus on specific items. For example, perhaps an audit requires you to report on all administrative-level actions performed on a subscription. You can create a query to filter on only these actions and sort the results by user, date, or another value.
For more information, see Log queries in Azure Monitor.
View user activity across domains
To view activity from individual users across multiple domains, use the Activity Logs by Domain sample workbook.
Results can be filtered by domain name. You can also apply additional filters such as category, level, or resource group.
