2016/11/21 - AWS CloudTrail - 2 new 2 updated api methods
Changes This release of AWS CloudTrail supports configuring your trail with event selectors. Use event selectors to specify the type of events that you want your trails to log. You can configure event selectors to log read-only, write-only, or all events. CloudTrail supports logging Amazon S3 object level APIs such as GetObject, DeleteObject, and PutObject. You can configure event selectors for your trail to log object level operations.
Configures an event selector for your trail. Use event selectors to specify the type of events that you want your trail to log. When an event occurs in your account, CloudTrail evaluates the event selectors in all trails. For each trail, if the event matches any event selector, the trail processes and logs the event. If the event doesn't match any event selector, the trail doesn't log the event.
Example
You create an event selector for a trail and specify that you want write-only events.
The EC2 GetConsoleOutput and RunInstances API operations occur in your account.
CloudTrail evaluates whether the events match your event selectors.
The RunInstances is a write-only event and it matches your event selector. The trail logs the event.
The GetConsoleOutput is a read-only event but it doesn't match your event selector. The trail doesn't log the event.
The PutEventSelectors operation must be called from the region in which the trail was created; otherwise, an InvalidHomeRegionException is thrown.
You can configure up to five event selectors for each trail. For more information, see Configuring Event Selectors for Trails in the AWS CloudTrail User Guide .

Specify if you want your event selector to include management events for your trail.
For more information, see Management Events in the AWS CloudTrail User Guide .
By default, the value is true .
DataResources (list) --
CloudTrail supports logging only data events for S3 objects. You can specify up to 50 S3 buckets and object prefixes for an event selector.
For more information, see Data Events in the AWS CloudTrail User Guide .
(dict) --
The Amazon S3 objects that you specify in your event selectors for your trail to log data events. Data events are object level API operations that access S3 objects, such as GetObject , DeleteObject , and PutObject . You can specify up to 50 S3 buckets and object prefixes for an event selector.
Example
You create an event selector for a trail and specify an S3 bucket and an empty prefix, such as arn:aws:s3:::bucket-1/ .
You upload an image file to bucket-1 .
The PutObject API operation occurs on an object in the S3 bucket that you specified in the event selector. The trail processes and logs the event.
You upload another image file to a different S3 bucket named arn:aws:s3:::bucket-2 .
The event occurs on an object in an S3 bucket that you didn't specify in the event selector. The trail doesn’t log the event.
Type (string) --
The resource type in which you want to log data events. You can specify only the following value: AWS::S3::Object .
Values (list) --
A list of ARN-like strings for the specified S3 objects.
To log data events for all objects in an S3 bucket, specify the bucket and an empty object prefix such as arn:aws:s3:::bucket-1/ . The trail logs data events for all objects in this S3 bucket.
To log data events for specific objects, specify the S3 bucket and object prefix such as arn:aws:s3:::bucket-1/example-images . The trail logs data events for objects in this S3 bucket that match the prefix.

{'LookupAttributes': {'AttributeKey': ['EventSource']}}
Response {'Events': {'EventSource': 'string'}}
Looks up API activity events captured by CloudTrail that create, update, or delete resources in your account. Events for a region can be looked up for the times in which you had CloudTrail turned on in that region during the last seven days. Lookup supports the following attributes:
Event ID
Event name
Resource name
Resource type
User name
All attributes are optional. The default number of results returned is 10, with a maximum of 50 possible. The response includes a token that you can use to get the next page of results.
Warning
The rate of lookup requests is limited to one per second per account. If this limit is exceeded, a throttling error occurs.
Warning
Events that occurred during the selected time range will not be available for lookup if CloudTrail logging was not enabled when the events occurred.
