Introduction to Cloud Asset Inventory

Cloud Asset Inventory provides inventory services based on a time series database. This database keeps a five week history of Google Cloud asset metadata. The Cloud Asset Inventory export service allows you to export all asset metadata at a certain timestamp or export event change history during a timeframe.

Features

Export asset metadata at a timestamp

The Cloud Asset Inventory export service allows you to export all the asset metadata at a given timestamp to a Cloud Storage file.

Export asset history

The Cloud Asset Inventory export service allows you to export the event change history of multiple assets during a given timeframe. The exported event change history shows you all the create, delete, and update events for the specifed assets over time.

Supported resource types

Important: When exporting certain resources, some response field names have changed. See the mapping table for more information.

Cloud Asset Inventory currently supports and returns the following resource types. You need to use the correct resource name format when using Cloud Asset Inventory.

Key Concepts

Asset

An asset refers to a Google Cloud resource or policy. Examples of resources include Compute Engine virtual machines (VMs), Cloud Storage buckets, and App Engine instances. Examples of policies include Cloud Identity and Access Management (Cloud IAM) policies and org policies (currently not supported).

Asset content type

Cloud Asset Inventory supports the following asset types:

• Resource: Resource metadata of a Google Cloud asset.

• IAM Policy: Metadata of the Cloud IAM Policy set on a Google Cloud asset.

• Org Policy: Metadata of the Organization Policy set on a Resource Manager asset.

• Access Policy: Metadata of the Access Context Manager Policy (VPC Service Controls Policy) set on an organization.

Asset snapshot

An asset snapshot is the set of available assets under a Cloud Asset Inventory project, folder, or organization at a timestamp.

Asset history

For a given asset, asset history includes all metadata create, delete, and update events between timestamp T₁ and T₂.
