    Result

    Discovery populates the CMDB with the discovered resources and updates the information on the Resources tab. You can view Discovery results in the Discovery Log tab.
    Note:
    By default, Discovery stores the discovered VM hardware types in the Hardware Type [cmdb_ci_compute_template] table. If you notice an unusually large number of records in this table, use the Cloud Hardware Type [cmdb_ci_cloud_hardware_type] table to store the discovered VM hardware types. For more information, see Enable the Cloud Hardware Type class extension. All Cloud Provisioning and Governance features, such as provisioning, quotas, and so on continue to work as is after you switch to the Cloud Hardware Type table.
