The Azure Activity Log is the appropriate service for generating a monthly report for all resource deployments in an Azure subscription. This service provides a record of all activities within your Azure subscription, including resource creation, modification, and deletion. It allows users to see a comprehensive history of operations carried out on different resources in the subscription, which is essential for compliance, auditing, and tracking changes over time.

When using the Azure Activity Log, you can query the events related to resource deployments and compile them into a report. The data can be exported to other tools or services for further analysis or reporting, making it a suitable choice for monthly reporting needs.

Other services, while valuable in their own right, do not focus specifically on providing a detailed log of resource deployments. Azure Analysis Services is primarily used for data modeling and analytics, Azure Monitor action groups are used to manage notifications and automated actions in response to alerts, and Azure Advisor provides recommendations on optimizing infrastructure and improving performance, but none of these services deliver the detailed activity logging related to resource deployments as effectively as the Activity Log.
