To discover VM\ninstances and databases in your on-premises environment, use\n[guest discovery](/migration-center/docs/run-guest-discovery) or an [IP range scan](/migration-center/docs/run-ip-range-scan).\n\nFor VMware VM instances, Amazon EC2 instances, and Azure VM\ninstances, the\n`mcdc` CLI collects data such as the operating system,\nstorage configuration, the number of cores, and performance data.\n\nFor Amazon RDS databases, the `mcdc` CLI captures\ninformation such as the database engine, name, edition, version, and shape,\nalong with the following performance data:\n\n- CPU utilization\n- Memory utilization\n- Disk read and write input/output operations per second (IOPS)\n- Network ingress and egress\n\nBefore you begin\n----------------\n\n1. Review the [requirements for downloading and running the `mcdc` CLI](/migration-center/docs/review-collector-cli-requirements).\n2. Complete the steps to [download `mcdc` CLI](/migration-center/docs/download-collector-cli).\n\nWhat's next\n-----------\n\n- Learn how to [discover VM instances on VMware](/migration-center/docs/discover-vmware-vms).\n- Learn how to [discover EC2 instances and databases in AWS](/migration-center/docs/discover-aws-vms).\n- Learn how to [discover Azure VM instances](/migration-center/docs/discover-azure-vms)."]]
