You manage an on-premises infrastructure based on VMware vSphere 6.0 with 250 virtual machines (VMs). You are evaluating the possibility of moving those VMs to Azure. You decide to use the Azure…

Azure Migrate requires a higher statistics collection level in vCenter Server to gather the detailed performance data necessary for comprehensive assessments, especially for accurate right-sizing recommendations and performance history. The default level (typically 1) provides basic metrics, so increasing it to level 3 ensures all available information is collected.

While the collector VM needs appropriate permissions, the question implies a data collection completeness issue from vCenter's internal settings, not necessarily an access issue for the collector itself.

Level 2 provides more data than Level 1, but Level 3 is typically specified as the requirement for the most comprehensive data collection needed for detailed Azure Migrate assessments, including historical performance.

A read-only user account is generally sufficient for discovery and assessment in Azure Migrate; changing to it wouldn't resolve missing information if the vCenter statistics collection level is the underlying problem.
