You need to deliver an interactive, shareable view to an application team that combines: 1) metrics charts (CPU, requests), 2) KQL query results from Log Analytics, 3) parameters to select resource group and time range, and 4) the ability to export and version-control the artifact for deployment to other subscriptions. What should you build?

An Azure Monitor Workbook is the correct choice because it directly supports all specified requirements. Workbooks allow you to combine metrics charts, KQL query results from Log Analytics, and interactive parameters (like resource group and time range) into a single, shareable report. They can also be exported as JSON templates for version control and deployment across subscriptions. An Azure Dashboard with metrics tiles can display metrics and some KQL results but lacks the rich interactivity and parameterization of Workbooks, and its export/versioning capabilities are more limited. A Metrics Explorer saved chart is too specialized, focusing only on metrics, and doesn't integrate KQL or advanced parameters. A Power BI report could connect to Azure Monitor data but would require more setup, external tooling, and wouldn't be as natively integrated for interactive Azure monitoring as a Workbook.
