      ));

#### Parameters

$args
  `array`
  $arg Associative array containing the following keys (required keys are bold):
  - Name => (string)

    Specifies the name of the trail. The name 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)
  - S3BucketName => (string)

    Specifies the name of the Amazon S3 bucket designated for publishing log files. See Amazon S3 Bucket Naming Requirements.

  - S3KeyPrefix => (string)

    Specifies the Amazon S3 key prefix that comes after the name of the bucket you have designated for log file delivery. For more information, see Finding Your CloudTrail Log Files. The maximum length is 200 characters.

    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.
  - CloudWatchLogsLogGroupArn => (string)

    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.

  - CloudWatchLogsRoleArn => (string)

    Specifies the role for the CloudWatch Logs endpoint to assume to write to a user's log group.

  - KmsKeyId => (string)

    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

# `public `Guzzle\Service\Resource\Model``
`listPublicKeys( array $args = array() )`

Executes the ListPublicKeys operation.

Returns all public keys whose private keys were used to sign the digest files within the specified time range. The public key is needed to validate digest files that were signed with its corresponding private key.

CloudTrail uses different private/public key pairs per region. Each digest file is signed with a private key unique to its region. Therefore, when you validate a digest file from a particular region, you must look in the same region for its corresponding public key.

#### Examples

- Basic formatting example

      $result = $client->listPublicKeys(array(
          'StartTime' => 'mixed type: string (date format)|int (unix timestamp)|\DateTime',

  - StartTime => (string [date format]|int [unix timestamp]|\DateTime)

    Optionally specifies, in UTC, the start of the time range to look up public keys for CloudTrail digest files. If not specified, the current time is used, and the current public key is returned.

  - EndTime => (string [date format]|int [unix timestamp]|\DateTime)

    Optionally specifies, in UTC, the end of the time range to look up public keys for CloudTrail digest files. If not specified, the current time is used.

  - NextToken => (string)

    Reserved for future use.

#### Returns

# `public `Guzzle\Service\Resource\Model``
`lookupEvents( array $args = array() )`

Executes the LookupEvents operation.

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 five different attributes: time range (defined by a start time and end time), user name, event name, resource type, and resource name. All attributes are optional. The maximum number of attributes that can be specified in any one lookup request are time range and one other attribute. 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.

The rate of lookup requests is limited to one per second per account. If this limit is exceeded, a throttling error occurs. Events that occurred during the selected time range will not be available for lookup if CloudTrail logging was not enabled when the events occurred.

#### Examples

- Basic formatting example

      $result = $client->lookupEvents(array(
          'LookupAttributes' => array(
              array(
                  // AttributeKey is required

For a list of resource types supported for event lookup, see Resource Types Supported for Event Lookup.

        - ResourceName => (string)

          The name of the resource referenced by the event returned. These are user-created names whose values will depend on the environment. For example, the resource name might be "auto-scaling-test-group" for an Auto Scaling Group or "i-1234567" for an EC2 Instance.

    - CloudTrailEvent => (string)

      A JSON string that contains a representation of the event returned.

#### Examples

- Basic formatting example

      $result = $client->updateTrail(array(
          // Name is required
          'Name' => 'string',

      ));

#### Parameters

$args
  `array`
  $arg Associative array containing the following keys (required keys are bold):
  - Name => (string)

    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.

  - S3BucketName => (string)

    Specifies the name of the Amazon S3 bucket designated for publishing log files. See Amazon S3 Bucket Naming Requirements.

  - S3KeyPrefix => (string)

    Specifies the Amazon S3 key prefix that comes after the name of the bucket you have designated for log file delivery. For more information, see Finding Your CloudTrail Log Files. The maximum length is 200 characters.

  - SnsTopicName => (string)

    Specifies the name of the Amazon SNS topic defined for notification of log file delivery. The maximum length is 256 characters.

  - IncludeGlobalServiceEvents => (bool)

    Specifies whether the trail is publishing events from global services such as IAM to the log files.

  - EnableLogFileValidation => (bool)

    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.
  - CloudWatchLogsLogGroupArn => (string)

    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.

  - CloudWatchLogsRoleArn => (string)

    Specifies the role for the CloudWatch Logs endpoint to assume to write to a user's log group.

  - KmsKeyId => (string)

    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
