Managing External Asset Discovery
In Oracle Cloud Migrations, asset discovery identifies and collects the metadata for the assets from the external environment. It then represents the relevant metadata in the inventory assets to facilitate the migration process.
The discovery process collects historical metrics to Oracle Cloud Infrastructure inventory and real-time metrics to Oracle Cloud Infrastructure monitoring. This data helps in providing meaningful suggestions for sizes of migrated assets based on the current usage of assets.
- Historical metrics: These metrics are collected automatically.
- Monitoring or Real-time metrics: The monitoring metrics are precise when compared to historical metrics and they use the OCI monitoring service. If the usage of monitoring metrics exceeds the capacity of free usage, you incur extra costs.
Install the remote agent appliance VM on a vCenter server and register the agent in an Oracle Cloud Migrations environment. For more information, see:
- Add the required IAM policies.
Create a source environment.
- To import, create, or view assets, create an inventory.Note
This task is required before you start using your tenancy in OCI or if you haven't created an inventory.
Required IAM Policies
You can create policies to allow user groups to access the external asset discovery resources.
View the verb to permission mapping for asset discovery to decide which verb meets the access requirements. For example,
inspect allows users to view the list of all the asset sources in a compartment and
read allows users to view the known connections to the asset source by the asset source ID.
