Cloud Asset Inventory overview

Cloud Asset Inventory is a global metadata inventory service that lets you view, search, export, monitor, and analyze your Google Cloud asset metadata, with up to 35 days of create, update, and delete history. Assets that haven't changed in the past 35 days report their latest status.

Asset metadata can come from the following places:

Google Cloud resources, such as Compute Engine VM instances, Cloud Storage buckets, and App Engine instances.
Policiesset on Google Cloud resources, such as IAM policies, organization policies, and Access Context Manager policies.
Runtime informationfrom OS inventory management .

Here's how you can work with your assets:

Listyour assets and their relationships in a particular project, folder, or organization, and get asset history up to 35 days in the past .
Searchfor your resources and their IAM allow policies using a custom query language, or query your assets with BigQuery SQL .
Exportyour asset metadata to BigQuery or Cloud Storage .
Analyzewhat would happen if a resource was moved to another project .
Analyzeyour IAM and organization policies on resources, and Viewyour effective IAM policies on resources to see who has access to what.
Monitoryour assets for changes by setting up and subscribing to a feed .
Generate insightsfrom your assets to help improve your security posture.

Asset types, asset names, and content types

Cloud Asset Inventory offers multiple methods to interact with your assets. Depending on the method you use and the response detail you want, you might need to specify asset types, asset names, and content types in your requests.

Asset types

Some Cloud Asset Inventory methods return results based on asset types. Asset types include Google Cloud resources, policies, OS inventory runtime information, and relationships. The available asset types and the Cloud Asset Inventory methods that support them are detailed in Asset types .

Asset names

Some Cloud Asset Inventory methods return results based on asset names. When specifying an asset name, you must use its full resource name. See Asset names for a list of full resource names.

Content types

You can request additional metadata on a resource by specifying a metadata content type. If you don't specify a content type, then only a basic response is returned, containing information such as the asset name, the last time it was updated, and what projects, folders, and organizations it belongs to.

Content type names differ depending on how you interact with Cloud Asset Inventory. The RPC and REST API names are the same. However, the gcloud CLI content type names follow a different pattern. For consistency and ease of explanation, the rest of this documentation refers to content types by their RPC and REST names.

The following table details the content types and their descriptions:

RPC and REST name	gcloud CLI name
`ACCESS_POLICY`	`access-policy`	The Access Context Manager policy set on an asset.
`IAM_POLICY`	`iam-policy`	The IAM policy metadata binding to the resource.
`ORG_POLICY`	`org-policy`	The organization policy metadata set on an asset. This content type outputs legacy organization policy v1. For organization policy v2, try the `resource` content type and a resource type of `orgpolicy.googleapis.com/Policy` .
`OS_INVENTORY`	`os-inventory`	The runtime OS inventory information. To enable OS inventory, complete the relevant steps in Set up VM Manager .
`RELATIONSHIP`	`relationship`	Only available for Security Command Center Premium and Enterprise tier subscribers. Many Google Cloud assets are connected to each other by relationships. For example, a Compute instance group can contain a Compute instance , or a GKE cluster can contain a node . Relationship data is available from May 30th, 2022. A relationship might have its own update timestamp, because it might be inferred at a different time than the source asset updates. See Relationship types for a list of the supported relationships.
`RESOURCE`	`resource`	The resource's metadata.

How responses change with content type

The following examples show how responses change when listing VM instances in a project through Cloud Asset Inventory with different content types.

No content type

If you specify no content type when listing VM instances, you receive only the instance names, the last time they were updated, and what projects, folders, and organizations they belong to.

IAM_POLICY content type

If you specify the IAM_POLICY content type, you also receive the IAM bindings on the VM, if there are any.

If you specify the RESOURCE content type, you also receive all the metadata associated with the VM.
