Inventory discovery lets you scan and list VMware virtual machine (VM)
instances, Amazon Elastic Compute Cloud (EC2) instances, Amazon Relational
Database Service (RDS) databases, and Azure VM instances
by using the Migration Center discovery client CLI. To discover VM
instances and databases in your on-premises environment, use
guest discovery or an IP range scan.
For VMware VM instances, Amazon EC2 instances, and Azure VM
instances, the
mcdc CLI collects data such as the operating system,
storage configuration, the number of cores, and performance data.
For Amazon RDS databases, the mcdc CLI captures
information such as the database engine, name, edition, version, and shape,
along with the following performance data:
CPU utilization
Memory utilization
Disk read and write input/output operations per second (IOPS)
