-- | Specifies the Amazon S3 key prefix that comes after the name of the

-- The maximum length is 200 characters.

-- | Specifies the name of the Amazon SNS topic defined for notification of

utSNSTopicName :: Lens' UpdateTrail (Maybe Text)
utSNSTopicName = lens _utSNSTopicName (\ s a -> s{_utSNSTopicName = a});

-- | Specifies whether log file validation is enabled. The default is false.
--
-- When you disable log file integrity validation, the chain of digest
-- files is broken after one hour. CloudTrail will not create digest files
-- for log files that were delivered during a period in which log file
-- integrity validation was disabled. For example, if you enable log file
-- integrity validation at noon on January 1, disable it at noon on January
-- 2, and re-enable it at noon on January 10, digest files will not be
-- created for the log files delivered from noon on January 2 to noon on
-- January 10. The same applies whenever you stop CloudTrail logging or
-- delete a trail.
utEnableLogFileValidation :: Lens' UpdateTrail (Maybe Bool)
utEnableLogFileValidation = lens _utEnableLogFileValidation (\ s a -> s{_utEnableLogFileValidation = a});

-- | Specifies a log group name using an Amazon Resource Name (ARN), a unique
-- identifier that represents the log group to which CloudTrail logs will
-- be delivered. Not required unless you specify CloudWatchLogsRoleArn.
utCloudWatchLogsLogGroupARN :: Lens' UpdateTrail (Maybe Text)
utCloudWatchLogsLogGroupARN = lens _utCloudWatchLogsLogGroupARN (\ s a -> s{_utCloudWatchLogsLogGroupARN = a});

-- | Specifies the KMS key ID to use to encrypt the logs delivered by
-- CloudTrail. The value can be a 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.
--
-- Examples:
--
-- -   alias\/MyAliasName
-- -   arn:aws:kms:us-east-1:123456789012:alias\/MyAliasName
-- -   arn:aws:kms:us-east-1:123456789012:key\/12345678-1234-1234-1234-123456789012
-- -   12345678-1234-1234-1234-123456789012
utKMSKeyId :: Lens' UpdateTrail (Maybe Text)
utKMSKeyId = lens _utKMSKeyId (\ s a -> s{_utKMSKeyId = a});

-- | Specifies whether the trail is publishing events from global services
-- such as IAM to the log files.
utIncludeGlobalServiceEvents :: Lens' UpdateTrail (Maybe Bool)
utIncludeGlobalServiceEvents = lens _utIncludeGlobalServiceEvents (\ s a -> s{_utIncludeGlobalServiceEvents = a});

-- | Specifies the role for the CloudWatch Logs endpoint to assume to write
-- to a user\'s log group.
utCloudWatchLogsRoleARN :: Lens' UpdateTrail (Maybe Text)
utCloudWatchLogsRoleARN = lens _utCloudWatchLogsRoleARN (\ s a -> s{_utCloudWatchLogsRoleARN = a});

-- | Specifies the name of the Amazon S3 bucket designated for publishing log
-- files. See
-- <http://docs.aws.amazon.com/awscloudtrail/latest/userguide/create_trail_naming_policy.html Amazon S3 Bucket Naming Requirements>.
utS3BucketName :: Lens' UpdateTrail (Maybe Text)
utS3BucketName = lens _utS3BucketName (\ s a -> s{_utS3BucketName = a});

-- | Specifies the name of the trail or trail ARN. If 'Name' is a trail name,
-- the string must meet the following requirements:
--
-- -   Contain only ASCII letters (a-z, A-Z), numbers (0-9), periods (.),
--     underscores (_), or dashes (-)
-- -   Start with a letter or number, and end with a letter or number
-- -   Be between 3 and 128 characters
-- -   Have no adjacent periods, underscores or dashes. Names like
--     'my-_namespace' and 'my--namespace' are invalid.
-- -   Not be in IP address format (for example, 192.168.5.4)
--
-- If 'Name' is a trail ARN, it must be in the format
-- 'arn:aws:cloudtrail:us-east-1:123456789012:trail\/MyTrail'.
