You plan to migrate an on-premises SAP development system to Azure. Before the migration, you need to check the usage of the source system hardware…

The ST06 transaction, also known as the Operating System Monitor, is the standard SAP tool used to analyze the performance and resource consumption of the underlying operating system directly from the SAP GUI. It provides detailed historical and real-time data on key hardware metrics, including CPU utilization, physical and virtual memory usage, disk I/O, and network statistics. This information is fundamental during the assessment phase of a migration to Azure, as it allows architects to accurately size the target Azure Virtual Machines based on the actual workload of the source system.

A. SM51 is used to list and manage the active SAP application server instances within a system, not for detailed OS hardware monitoring.

B. DB01 is a database-specific transaction used to analyze exclusive database lock waits, which is unrelated to general hardware usage.

C. DB12 provides an overview of database backup and recovery logs and is used for data protection management, not performance monitoring.

SAP workload on Azure planning and deployment checklist: In the "Sizing" section

the documentation explicitly recommends using SAP tools for assessment: "Use the SAP OS monitor (transaction ST06) and other SAP tools to determine the resource utilization of your source systems." This directly supports using ST06 for pre-migration hardware checks.
