Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.

AdvancedEventSelectors

The advanced event selectors to use to select the events for the data store. You can configure up to five advanced event selectors for each event data store.

For more information about how to use advanced event selectors to log CloudTrail events, see Log events by using advanced event selectors in the CloudTrail User Guide.

For more information about how to use advanced event selectors to include AWS Config configuration items in your event data store, see Create an event data store for AWS Config configuration items in the CloudTrail User Guide.

For more information about how to use advanced event selectors to include events outside of AWS events in your event data store, see Create an integration to log events from outside AWS in the CloudTrail User Guide.

Type: Array of AdvancedEventSelector objects

Required: No

BillingMode

The billing mode for the event data store determines the cost for ingesting events and the default and maximum retention period for the event data store.

The following are the possible values:

EXTENDABLE_RETENTION_PRICING - This billing mode is generally recommended if you want a flexible retention period of up to 3653 days (about 10 years). The default retention period for this billing mode is 366 days.
FIXED_RETENTION_PRICING - This billing mode is recommended if you expect to ingest more than 25 TB of event data per month and need a retention period of up to 2557 days (about 7 years). The default retention period for this billing mode is 2557 days.

The default value is EXTENDABLE_RETENTION_PRICING.

For more information about CloudTrail pricing, see AWS CloudTrail Pricing and Managing CloudTrail Lake costs.

Type: String

Valid Values: EXTENDABLE_RETENTION_PRICING | FIXED_RETENTION_PRICING

Required: No

KmsKeyId

Specifies the AWS KMS key ID to use to encrypt the events delivered by CloudTrail. The value can be an alias name prefixed by alias/, a fully specified ARN to an alias, a fully specified ARN to a key, or a globally unique identifier.

Important

Disabling or deleting the KMS key, or removing CloudTrail permissions on the key, prevents CloudTrail from logging events to the event data store, and prevents users from querying the data in the event data store that was encrypted with the key. After you associate an event data store with a KMS key, the KMS key cannot be removed or changed. Before you disable or delete a KMS key that you are using with an event data store, delete or back up your event data store.

CloudTrail also supports AWS KMS multi-Region keys. For more information about multi-Region keys, see Using multi-Region keys in the AWS Key Management Service Developer Guide.

Examples:

alias/MyAliasName
arn:aws:kms:us-east-2:123456789012:alias/MyAliasName
arn:aws:kms:us-east-2:123456789012:key/12345678-1234-1234-1234-123456789012
12345678-1234-1234-1234-123456789012

Type: String

Length Constraints: Minimum length of 1. Maximum length of 350.

Pattern: ^[a-zA-Z0-9._/\-:]+$

Required: No

MultiRegionEnabled

Specifies whether the event data store includes events from all Regions, or only from the Region in which the event data store is created.

Type: Boolean

Required: No

Name

The name of the event data store.

Type: String

Length Constraints: Minimum length of 3. Maximum length of 128.

Pattern: ^[a-zA-Z0-9._\-]+$

Required: Yes

OrganizationEnabled

Specifies whether an event data store collects events logged for an organization in AWS Organizations.

Type: Boolean

Required: No

RetentionPeriod

The retention period of the event data store, in days. If BillingMode is set to EXTENDABLE_RETENTION_PRICING, you can set a retention period of up to 3653 days, the equivalent of 10 years. If BillingMode is set to FIXED_RETENTION_PRICING, you can set a retention period of up to 2557 days, the equivalent of seven years.

CloudTrail Lake determines whether to retain an event by checking if the eventTime of the event is within the specified retention period. For example, if you set a retention period of 90 days, CloudTrail will remove events when the eventTime is older than 90 days.

Note

If you plan to copy trail events to this event data store, we recommend that you consider both the age of the events that you want to copy as well as how long you want to keep the copied events in your event data store. For example, if you copy trail events that are 5 years old and specify a retention period of 7 years, the event data store will retain those events for two years.

Type: Integer

Valid Range: Minimum value of 7. Maximum value of 3653.

Required: No

StartIngestion

Specifies whether the event data store should start ingesting live events. The default is true.

Type: Boolean

Required: No

TagsList

A list of tags.

Type: Array of Tag objects

Array Members: Maximum number of 200 items.

Required: No

TerminationProtectionEnabled

Specifies whether termination protection is enabled for the event data store. If termination protection is enabled, you cannot delete the event data store until termination protection is disabled.

Type: Boolean

Required: No
