This topic describes how to use Cloud Migration Hub (CMH) to survey your resources on Alibaba Cloud in online mode. This topic helps you collect information about Alibaba Cloud resources from multiple regions and zones at a time.
Video tutorial
In the latest version of the online resource survey feature, you do not need to confirm resources before the resources can be imported to CMH. The system automatically confirms the resources and imports them to the resource list.
Start a survey
Log on to the CMH console. In the left-side navigation pane, choose Assessment > Resource Collection. On the Online Collection tab of the Resource Collection page, click Start in the Import From Alibaba Cloud section. In the Import From Alibaba Cloud dialog box, select the regions and zones from which you want to collect resource information and the types of resources whose information you want to collect. Then, CMH calls Cloud Config in the background to survey resources and collect resource information.
If you use CMH to survey Alibaba Cloud resources for the first time, the service-linked role for CMH is automatically created. If you have not activated the Cloud Config service, the system prompts you to activate the service first. You can click the link in the message to go to the Cloud Config console. After you activate the Cloud Config service, you can use CMH to survey Alibaba Cloud resources.
View survey results
When the progress of your survey task reaches 100%, you can click the task ID to go to the details page of the task and view the survey results. You can also export relevant results for analysis on your on-premises device. After the survey is complete, the resources are automatically imported to CMH and are displayed in the resource list.
The surveyed resources are classified into two types based on the types of Alibaba Cloud service instances: zone-specific resources and region-specific resources. Configurations of some region-specific instances may be related to zone-specific resources. Therefore, the corresponding region-specific resources are displayed in the survey results. If you want to view only the instances in zones, click the Zone Resources tab.
