public sealed class Feed : IMessage<Feed>, IEquatable<Feed>, IDeepCloneable<Feed>, IBufferMessage, IMessage
Reference documentation and code samples for the Google Cloud Asset Inventory v1 API class Feed.
An asset feed used to export asset updates to a destinations.
An asset feed filter controls what updates are exported.
The asset feed must be created within a project, organization, or
folder. Supported destinations are:
Pub/Sub topics.
A list of the full names of the assets to receive updates. You must specify
either or both of asset_names and asset_types. Only asset updates matching
specified asset_names or asset_types are exported to the feed.
Example:
//compute.googleapis.com/projects/my_project_123/zones/zone1/instances/instance1.
For a list of the full names for supported asset types, see Resource
name format.
A list of types of the assets to receive updates. You must specify either
or both of asset_names and asset_types. Only asset updates matching
specified asset_names or asset_types are exported to the feed.
Example: "compute.googleapis.com/Disk"
A condition which determines whether an asset update should be published.
If specified, an asset will be returned only when the expression evaluates
to true.
When set, expression field in the Expr must be a valid CEL expression on a TemporalAsset with name
temporal_asset. Example: a Feed with expression ("temporal_asset.deleted
== true") will only publish Asset deletions. Other fields of Expr are
optional.
Required. The format will be
projects/{project_number}/feeds/{client-assigned_feed_identifier} or
folders/{folder_number}/feeds/{client-assigned_feed_identifier} or
organizations/{organization_number}/feeds/{client-assigned_feed_identifier}
The client-assigned feed identifier must be unique within the parent
project/folder/organization.
public RepeatedField<string> RelationshipTypes { get; }
A list of relationship types to output, for example:
INSTANCE_TO_INSTANCEGROUP. This field should only be specified if
content_type=RELATIONSHIP.
If specified:
it outputs specified relationship updates on the [asset_names] or the
[asset_types]. It returns an error if any of the [relationship_types]
doesn't belong to the supported relationship types of the [asset_names] or
[asset_types], or any of the [asset_names] or the [asset_types] doesn't
belong to the source types of the [relationship_types].
Otherwise:
it outputs the supported relationships of the types of [asset_names] and
[asset_types] or returns an error if any of the [asset_names] or the
[asset_types] has no replationship support.
See Introduction to Cloud Asset
Inventory
for all supported asset types and relationship types.
