Which tool should an IT manager use to query metadata for all VMs across multiple subscriptions?

Azure Resource Graph is the correct tool because it provides an efficient and performant way to explore Azure resources at scale across multiple subscriptions. It uses a Kusto Query Language (KQL)-based query language to filter, group, and sort resources, making it ideal for querying metadata for all VMs. Azure Advisor offers recommendations for optimizing Azure resources, not a querying mechanism. Azure Cost Management focuses on tracking and optimizing cloud spending. Azure Monitor collects and analyzes telemetry data from Azure resources, but it's not designed for broad metadata queries across subscriptions like Resource Graph.
