2018/08/07 - Amazon Elastic Compute Cloud - 3 updated api methods
Changes Amazon VPC Flow Logs adds support for delivering flow logs directly to S3
{'DryRun': 'boolean',
'LogDestination': 'string',
'LogDestinationType': 'cloud-watch-logs | s3'}
Creates one or more flow logs to capture information about IP traffic for a specific network interface, subnet, or VPC.
Flow log data for a monitored network interface is recorded as flow log records, which are log events consisting of fields that describe the traffic flow. For more information, see Flow Log Records in the Amazon Virtual Private Cloud User Guide .
When publishing to CloudWatch Logs, flow log records are published to a log group, and each network interface has a unique log stream in the log group. When publishing to Amazon S3, flow log records for all of the monitored network interfaces are published to a single log file object that is stored in the specified bucket.
For more information, see VPC Flow Logs in the Amazon Virtual Private Cloud User Guide .

boolean
Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation . Otherwise, it is UnauthorizedOperation .
string
Unique, case-sensitive identifier that you provide to ensure the idempotency of the request. For more information, see How to Ensure Idempotency.
string
The ARN for the IAM role that's used to post flow logs to a log group.
string
The name of the log group.
list
[REQUIRED]
One or more subnet, network interface, or VPC IDs.
Constraints: Maximum of 1000 resources
(string) --
string
[REQUIRED]
The type of resource on which to create the flow log.
string
[REQUIRED]
The type of traffic to log.
string
Specifies the type of destination to which the flow log data is to be published. Flow log data can be published to CloudWatch Logs or Amazon S3. To publish flow log data to CloudWatch Logs, specify cloud-watch-logs . To publish flow log data to Amazon S3, specify s3 .
Default: cloud-watch-logs
string
Specifies the destination to which the flow log data is to be published. Flow log data can be published to an CloudWatch Logs log group or an Amazon S3 bucket. The value specified for this parameter depends on the value specified for LogDestinationType.
If LogDestinationType is not specified or cloud-watch-logs , specify the Amazon Resource Name (ARN) of the CloudWatch Logs log group.
If LogDestinationType is s3 , specify the ARN of the Amazon S3 bucket. You can also specify a subfolder in the bucket. To specify a subfolder in the bucket, use the following ARN format: bucket_ARN/subfolder_name/ . For example, to specify a subfolder named my-logs in a bucket named my-bucket , use the following ARN: arn:aws:s3:::my-bucket/my-logs/ .

(dict) --
A filter name and value pair that is used to return a more specific list of results from a describe operation. Filters can be used to match a set of resources by specific criteria, such as tags, attributes, or IDs. The filters supported by a describe operation are documented with the describe operation. For example:
DescribeAvailabilityZones
DescribeImages
DescribeInstances
DescribeKeyPairs
DescribeSecurityGroups
DescribeSnapshots
DescribeSubnets
DescribeTags
DescribeVolumes
DescribeVpcs

This value can be between 5 and 1000. If MaxResults is given a value larger than 1000, only 1000 results are returned. You cannot specify this parameter and the flow log IDs parameter in the same request.
