Monitor asset changes with Pub/Sub

You can receive real-time notifications about resource and policy changes by creating and subscribing to a feed.

When you create the feed, you can specify that you want to monitor changes of supported resource types, IAM policies, access policies, and organization policies in an organization, folder, project. Additionally, you can add conditions to your feed so that you only receive notifications for certain types of changes to an asset.

After creating a feed, you receive notifications through Pub/Sub whenever the specified assets change. The first message published to the Pub/Sub topic is a welcome message in the format of a string, and all following messages are in the format of a TemporalAsset.

Here's a sample Pub/Sub message for the RESOURCE content type.

{
  "asset":{
    "ancestors":[
      "projects/000000000000",
      "folders/000000000000",
      "organizations/000000000000"
    ],
    "assetType":"storage.googleapis.com/Bucket",
    "name":"//storage.googleapis.com/my-bucket",
    "resource":{

  },

      "folders/000000000000",

    ],
    "assetType":"storage.googleapis.com/Bucket",
    "name":"//storage.googleapis.com/my-bucket",

  }
}

To learn more about Pub/Sub or how to set up subscriptions, see the Pub/Sub documentation.

Tip: You can connect real-time notifications to your workloads. For example, you could run a Cloud Run function to reverse a resource change after it has been detected.

Before you begin

1. Enable the Cloud Asset Inventory API in the project you're running Cloud Asset Inventory commands from.

   Enable the Cloud Asset Inventory API

2. Make sure your account has the correct role to call the Cloud Asset Inventory API. For individual permissions for each call type, see Permissions.

3. Create a Pub/Sub topic, if you don't have one already.

Limitations

• It can take up to 10 minutes for any feed creation, update, or deletion to take effect.

• The project where a feed is created must outlive the feed. This is because the service account used to publish to the destination Pub/Sub topic is located in that project. A feed no longer functions and is deleted as soon as project deletion is permanent.

• You can create up to 200 feeds on a parent. This limit only applies to feeds directly following a parent and does not count the feeds of its children. For example, if you have 10 projects in an organization, each project can have up to 200 feeds, and the organization can also have up to 200 feeds.

Create feeds

gcloud

Feed conditions

To view only certain types of changes for a given asset, you can add a condition to your feed. Conditions are written in Common Expression Language (CEL).

Support for conditions is limited. In some cases, creating or updating feeds with conditions might result in a delay.

Limitations

• Condition expressions have a length limit of 3,000 characters.

• Most variable names in condition expressions are represented in lowercase with underscores between each word. For example, example_variable.

  The exception is the variable names of the sub-fields of data in the Resource object. These don't have word separators, and the first character of each word after the first is capitalized. For example, exampleVariable.

• Some validations on condition expressions are performed during feed creation or feed update time. However, such validations are not comprehensive, especially for conditions set on the temporal_asset.asset.resource.data field, which has a dynamic type. Where possible, filter your feed by using the appropriate gcloud CLI or REST API parameters instead.

• Notifications aren't sent if errors happen during evaluation time, however the errors are logged.

• For dynamic types in temporal_asset.asset.resource.data, conditions specified on absent fields trigger runtime errors and notifications aren't published. For example, for the condition temporal_asset.asset.resource.data.name != "my_name", if the name field is missing in an update, the evaluation fails and you don't receive notifications. If your condition only works in the presence of certain fields, add an existence check to the condition to ensure it is properly evaluated.

• Static enum types can be represented as either fully qualified path names or raw integers. For example, the following expressions are valid for prior_asset_state:

  temporal_asset.prior_asset_state == google.cloud.asset.v1.TemporalAsset.PriorAssetState.DOES_NOT_EXIST
  

  and

  temporal_asset.prior_asset_state == 3
  

  Dynamic enum types in temporal_asset.asset.resource.data are represented as raw strings. For example, the following expression is valid for the asset type cloudresourcemanager.googleapis.com/Project:

  temporal_asset.asset.resource.data.lifecycleState == "ACTIVE"
  

Create a condition expression with CEL

In a feed condition, Common Expression Language (CEL) is used to make boolean decisions based on attribute data. A condition expression consists of one or more statements that are joined using logic operators. Each statement expresses an attribute-based control rule that applies to the TemporalAsset to determine whether a notification is sent.

The following CEL features are the most important for feed conditions:

• Variables: Conditions use variables to express a given attribute, such as temporal_asset.deleted (Boolean) or temporal_asset.asset.name (String). These variables are populated with values based on the context at runtime.

• Operators: Every data type, such as String, supports a set of operators that can be used to create a logic expression. Most commonly, operators are used to compare the value contained in a variable with a literal value, such as temporal_asset.asset.name == "//cloudresourcemanager.googleapis.com/projects/12345". In this example, if the input value of temporal_asset.asset.name is //cloudresourcemanager.googleapis.com/projects/12345, then the expression evaluates to true.

• Functions: A function is a compound operator for data types that support more complex operations. In condition expressions, there are predefined functions that can be used in conjunction with a given data type. For example, temporal_asset.asset.name.contains("keyword") uses a function called contains to check if the value of temporal_asset.asset.name contains "keyword". If so, it evaluates to true.

• Logical operators: Conditions support logical operators that can be used to build complex logic expressions from basic expression statements: && (AND) and || (OR). These logical operators make it possible to use multiple input variables in a condition expression. For example: temporal_asset.deleted && temporal_asset.window.start_time.getFullYear() > 2020 joins two basic statements, and requires both statements to be met in order to produce a true evaluation result.

For more information about CEL features, see the language definition.

Using condition variables

Condition variables allow you to create conditions on different attributes. Supported condition variables are:

• temporal_asset: The most recent asset change in TemporalAsset format. If the condition evaluates to true, the TemporalAsset is sent to the configured destination.

Example condition expressions

The following condition expression sends notifications on creation events:

temporal_asset.deleted == false &&
temporal_asset.prior_asset_state == google.cloud.asset.v1.TemporalAsset.PriorAssetState.DOES_NOT_EXIST

The following condition expression sends notifications for resources that are located in folders 12345 and 23456:

"folders/12345" in temporal_asset.asset.ancestors ||
"folders/23456" in temporal_asset.asset.ancestors

The following condition expression sends notifications when new allowed rules are added to firewalls, assuming the asset type is already set to compute.googleapis.com/Firewall in the feed:

size(temporal_asset.asset.resource.data.allowed) >
size(temporal_asset.prior_asset.resource.data.allowed)

The following condition expression sends notifications for VM instances with n1-standard-1 machine type, assuming the asset type is already set to compute.googleapis.com/Instance in the feed:

temporal_asset.asset.resource.data.machineType.endsWith('/machineTypes/n1-standard-1')

The following condition expression sends notifications for storage buckets with any IAM policies for allUsers, assuming the asset type is set to storage.googleapis.com/Bucket, and the content type is set to IAM_POLICY in the feed:

temporal_asset.asset.iam_policy.bindings.exists(b, b.members.exists(m, m == "allUsers"))

The following condition expression sends a notification when a storage bucket with the test key in its label is deleted:

temporal_asset.deleted == true && temporal_asset.prior_asset_state == google.cloud.asset.v1.TemporalAsset.PriorAssetState.PRESENT && "test" in temporal_asset.prior_asset.resource.data.labels

Troubleshooting

If you're not receiving notifications for resource or IAM policy updates, the following steps can help you to troubleshoot:

• Make sure that the metadata has changed on your assets. The real-time feed only sends updates when the metadata of the supported resource types has changed. Operations such as uploading a new file to your Cloud Storage bucket does not trigger a metadata change.

• Make sure your assets match one of the asset names or types you specified in the feed.

• For project deletions, keep in mind that when you shut down a project you have 30 days to undo the operation. Because of this, the deleted field in the asset metadata is not set until the project is permanently deleted. To monitor projects that are pending deletion, you can set a condition on the project's lifecycleState field instead. For example: temporal_asset.asset.resource.data.lifecycleState == "DELETE_REQUESTED".

• Check the logs to see if there are errors when publishing updates to your topic.

Cloud Logging

When real-time feeds fail to send resources or IAM policy updates through Pub/Sub, Cloud Asset Inventory logs the error status and message in Logging. Logging is enabled by default, and belongs to Google Cloud Observability. Learn about Google Cloud Observability pricing.

Viewing real-time feed logs

The real-time feed log is indexed by a Pub/Sub topic. To see all logs:

1. Go to the Logs Explorer page in the Google Cloud console.

   Go to Logs Explorer

2. Click the Resource list, which is near to the Search all fields box.

3. Search for Cloud Pub/Sub Topic, and then click the Cloud Pub/Sub Topic resource type.

4. Click the topic ID you want to view.

5. Click Apply.

UTF-8 encoding is enforced for log fields. Characters that are not UTF-8 characters are replaced with question marks.

Logged information

Real-time feed log entries contain following types of information:

• General information shown in most Google Cloud logs, such as severity, project ID, project number, or timestamp.

• Real-time feed log fields in jsonPayload, which contains asset name, feed output config, and error status when publishing resource or IAM policy updates.

The following table shows what kind of information each field contains.

Field	Type and description
name	string Full Name of the feed. The format is one of the following: projects/PROJECT_ID/feeds/FEED_ID folders/FOLDER_ID/feeds/FEED_ID organizations/ORGANIZATION_ID/feeds/FEED_ID
asset_name	string Full name of the asset to receive updates. For example: //compute.googleapis.com/projects/my_project_123/zones/zone1/instances/instance1 See Resource names for more info.
condition	Expr Feed condition which determines whether an asset update should be published.
error_status	Status Status when there's a failure to publish asset updates to a feed.
feed_output_config	FeedOutputConfig Feed output configuration defining where the asset updates are published to.
