What tool should you use to see the sizes of your SQL Server databases running in an Azure virtual machine?

To determine the sizes of SQL Server databases running in an Azure virtual machine, the most suitable tool is the SQL virtual machine resource provider. This tool is specifically designed to manage SQL Server deployments on Azure, providing insights into the resources and performance metrics of the SQL Server instances running on virtual machines.

The SQL virtual machine resource provider allows you to access detailed information regarding your SQL Server databases, including sizes and growth metrics. This data can be critical for managing storage allocations, optimizing performance, and ensuring your databases are running efficiently.

While other tools like Azure Metrics Explorer and SQL Database Management Studio might provide useful information about resource usage or database management, they do not specifically focus on the SQL Server instance metrics in the context of Azure virtual machines. Azure Data Factory Monitoring is primarily concerned with data integration and workflow monitoring rather than database sizes. Hence, for the specific task of checking SQL Server database sizes on Azure virtual machines, using the SQL virtual machine resource provider is the most effective choice.
