ゲスト検出は、VM インスタンスと物理サーバーをスキャンし、実行中のアプリケーションに関するデータを収集します。このデータには、マシン構成、ハードウェア、ネットワーク、オープンファイル、サービス、プロセスに関する情報が含まれます。ゲスト検出では、オンプレミスと AWS で実行されている Microsoft SQL Server、PostgreSQL、MySQL データベースもスキャンして一覧表示します。
IP 範囲スキャンは、ネットワーク内のすべてのアセットを検出し、認証情報を検証して、検出されたアセットをスキャンします。ゲスト検出を使用してデータを収集します。IP アドレス範囲内に複数のマシンがある場合や、スキャンするインフラストラクチャについてあまり知識がない場合は、IP 範囲スキャンを使用します。
制限事項
mcdc CLI を使用して Migration Center にエクスポートできるのは、最大 10,000 台のマシンのデータのみです。

These asset discoveries scan the physical servers, virtual\nmachine (VM) instances, and databases in your infrastructure to collect\nthe necessary information for a successful migration assessment to\nGoogle Cloud.\n\nMigration Center provides advanced migration\nrecommendations and planning capabilities, however, if you're working with\nsensitive data and don't want to upload it to Google Cloud, you can\nchoose to [run an offline assessment](/migration-center/docs/run-offline-assessment)\ninstead.\n\nThe `mcdc` CLI has the following advantages:\n\n- It doesn't require installation.\n- It runs on Linux and Windows host machines.\n- It creates offline assessment reports.\n\nYou can use the data collected by running a `mcdc` CLI\ndiscovery to perform the following actions:\n\n- [Run an offline assessment](/migration-center/docs/run-offline-assessment).\n- [Export this data to Migration Center](/migration-center/docs/export-collected-data) where you can perform these actions:\n - [View and understand insights](/migration-center/docs/view-and-understand-insights)\n - [Group assets](/migration-center/docs/create-groups).\n - [Generate total cost of ownership (TCO) reports](/migration-center/docs/generate-tco-report)\n\n| **Note:** The `mcdc` CLI doesn't upload the collected data to Google Cloud until you choose to export it to Migration Center.\n\nAvailable collection methods\n----------------------------\n\nUsing the `mcdc` CLI, you can run the following collection\nmethods:\n\n- **Inventory discovery** scans and lists all of the VMware VM instances, Amazon Elastic Compute Cloud (EC2) instances, Amazon Relational Database Service (RDS) and Azure Virtual Machine instances ([Preview](/products#product-launch-stages)).\n- **Guest discovery** scans VM instances and physical servers, collecting data about the running applications. This data includes information about machine configurations, hardware, network, open files, services, and processes. Guest discovery also scans and lists Microsoft SQL Server, PostgreSQL, and MySQL databases that are running on-premises and on AWS.\n- **IP range scan** detects all assets in your network, verifies credentials, and scans the detected assets. It collects data using guest discovery. Use IP range scan when you have several machines in an IP address range or when you are unfamiliar with the infrastructure that you want to scan.\n\nLimitations\n-----------\n\n- The `mcdc` CLI can export data of only up to 10,000 machines to Migration Center.\n\nWhat's next\n-----------\n\n- Review the [requirements for downloading and running `mcdc` CLI](/migration-center/docs/review-collector-cli-requirements).\n- Learn more about the following discovery methods:\n\n - [Inventory discovery](/migration-center/docs/run-inventory-discovery)\n - [Guest discovery](/migration-center/docs/run-guest-discovery)\n - [IP range scan](/migration-center/docs/run-ip-range-scan)"]]
