RDS / Client / create_event_subscription
create_event_subscription#
- RDS.Client.create_event_subscription(**kwargs)#
Creates an RDS event notification subscription. This operation requires a topic Amazon Resource Name (ARN) created by either the RDS console, the SNS console, or the SNS API. To obtain an ARN with SNS, you must create a topic in Amazon SNS and subscribe to the topic. The ARN is displayed in the SNS console.
You can specify the type of source (
SourceType
) that you want to be notified of and provide a list of RDS sources (SourceIds
) that triggers the events. You can also provide a list of event categories (EventCategories
) for events that you want to be notified of. For example, you can specifySourceType
=db-instance
,SourceIds
=mydbinstance1
,mydbinstance2
andEventCategories
=Availability
,Backup
.If you specify both the
SourceType
andSourceIds
, such asSourceType
=db-instance
andSourceIds
=myDBInstance1
, you are notified of all thedb-instance
events for the specified source. If you specify aSourceType
but do not specifySourceIds
, you receive notice of the events for that source type for all your RDS sources. If you don’t specify either the SourceType or theSourceIds
, you are notified of events generated from all RDS sources belonging to your customer account.For more information about subscribing to an event for RDS DB engines, see Subscribing to Amazon RDS event notification in the Amazon RDS User Guide.
For more information about subscribing to an event for Aurora DB engines, see Subscribing to Amazon RDS event notification in the Amazon Aurora User Guide.

Request Syntax
response = client.create_event_subscription( SubscriptionName='string', SnsTopicArn='string', SourceType='string', EventCategories=[ 'string', ], SourceIds=[ 'string', ], Enabled=True|False, Tags=[ { 'Key': 'string', 'Value': 'string' }, ] )
- Parameters:
SubscriptionName (string) –
[REQUIRED]
The name of the subscription.
Constraints: The name must be less than 255 characters.
SnsTopicArn (string) –
[REQUIRED]
The Amazon Resource Name (ARN) of the SNS topic created for event notification. The ARN is created by Amazon SNS when you create a topic and subscribe to it.
SourceType (string) –
The type of source that is generating the events. For example, if you want to be notified of events generated by a DB instance, you set this parameter to
db-instance
. For RDS Proxy events, specifydb-proxy
. If this value isn’t specified, all events are returned.Valid Values:
db-instance
|db-cluster
|db-parameter-group
|db-security-group
|db-snapshot
|db-cluster-snapshot
|db-proxy
EventCategories (list) –
A list of event categories for a particular source type (
SourceType
) that you want to subscribe to. You can see a list of the categories for a given source type in the “Amazon RDS event categories and event messages” section of the Amazon RDS User Guide or the Amazon Aurora User Guide. You can also see this list by using theDescribeEventCategories
operation.(string) –
SourceIds (list) –
The list of identifiers of the event sources for which events are returned. If not specified, then all sources are included in the response. An identifier must begin with a letter and must contain only ASCII letters, digits, and hyphens. It can’t end with a hyphen or contain two consecutive hyphens.
Constraints:
If
SourceIds
are supplied,SourceType
must also be provided.If the source type is a DB instance, a
DBInstanceIdentifier
value must be supplied.If the source type is a DB cluster, a
DBClusterIdentifier
value must be supplied.If the source type is a DB parameter group, a
DBParameterGroupName
value must be supplied.If the source type is a DB security group, a
DBSecurityGroupName
value must be supplied.If the source type is a DB snapshot, a
DBSnapshotIdentifier
value must be supplied.If the source type is a DB cluster snapshot, a
DBClusterSnapshotIdentifier
value must be supplied.If the source type is an RDS Proxy, a
DBProxyName
value must be supplied.
(string) –
Enabled (boolean) – Specifies whether to activate the subscription. If the event notification subscription isn’t activated, the subscription is created but not active.
Tags (list) –
A list of tags. For more information, see Tagging Amazon RDS Resources in the Amazon RDS User Guide.
(dict) –
Metadata assigned to an Amazon RDS resource consisting of a key-value pair.
For more information, see Tagging Amazon RDS Resources in the Amazon RDS User Guide.
Key (string) –
A key is the required name of the tag. The string value can be from 1 to 128 Unicode characters in length and can’t be prefixed with
