Enable Cloud OS Image discovery

task australia Updated Sep 10, 2026 1 min read enable-cloud-os-image-discovery-pattern.md

Enable the Cloud OS Image [cmdb_ci_cloud_os_image] table to store the cloud OS image records for Amazon AWS Cloud, Microsoft Azure Cloud, Google Cloud Platform (GCP), Oracle Cloud Infrastructure (OCI), and IBM Cloud.

Before you begin

Ensure that the latest versions of the following applications are installed:
- Discovery and Service Mapping Patterns
- CMDB CI Class Models
Ensure that the application scope is the CMDB CI Class Models application.

Note: Cloud Provisioning and Governance (CPG) doesn’t support the New Cloud Image (cmdb_ci_cloud_os_image) table. If you’re currently utilizing CPG Provisioning flows or have intentions to do so, don’t migrate to the new Image Model.

Role required: admin

About this task

Each cloud service provider offers OS images to launch a Compute/VM instance. Cloud Discovery stores the discovered Image [cmdb_ci_os_template] table. This table is a dependent class on [cmdb_ci_logical_datacenter] or [cmdb_ci_cloud_service_account]. The new Image model creates one record for each public Image (object id) irrespective of the service account and populates them in the Cloud Image [cmdb_ci_cloud_os_image] table. There for, the new model reduces the number of records in the CMDB

Note: If you have Discovery and Service Mapping Patterns version 1.10.0- November 2023, proceed to the following procedure. If you have an earlier version, see the Knowledge Base article KB1000183.

Procedure

In the navigation filter, enter sys_properties.list.
In the Name field, search for sn_cmdb_ci_class.use_single_cloud_os_image.
Select the sn_cmdb_ci_class.use_single_cloud_os_image property.
In the Value field, enter true.
Select Update.

What to do next

Clean up the Image records. For more information, see the Knowledge Base article KB1537376.
Rerun the Cloud Discovery.
