This class represents one of two things:

Arguments in a call to a service

Use the attributes of this class as arguments to methods. You shouldn't make instances of this class. Each attribute should be used as a named argument in the calls that expect this type of object.

As an example, if Att1 is expected to be a Paws::OpsWorks::CloudWatchLogsLogStream object:

  $service_obj->Method(Att1 => { BatchCount => $value, ..., TimeZone => $value  });

Results returned from an API call

Use accessors for each attribute. If Att1 is expected to be an Paws::OpsWorks::CloudWatchLogsLogStream object:

  $result = $service_obj->Method(...);


Describes the Amazon CloudWatch logs configuration for a layer. For detailed information about members of this data type, see the CloudWatch Logs Agent Reference (


BatchCount => Int

  Specifies the max number of log events in a batch, up to 10000. The
default value is 1000.

BatchSize => Int

  Specifies the maximum size of log events in a batch, in bytes, up to
1048576 bytes. The default value is 32768 bytes. This size is
calculated as the sum of all event messages in UTF-8, plus 26 bytes for
each log event.

BufferDuration => Int

  Specifies the time duration for the batching of log events. The minimum
value is 5000ms and default value is 5000ms.

DatetimeFormat => Str

  Specifies how the time stamp is extracted from logs. For more
information, see the CloudWatch Logs Agent Reference

Encoding => Str

  Specifies the encoding of the log file so that the file can be read
correctly. The default is C<utf_8>. Encodings supported by Python
C<codecs.decode()> can be used here.

File => Str

  Specifies log files that you want to push to CloudWatch Logs.

File can point to a specific file or multiple files (by using wild card characters such as /var/log/system.log*). Only the latest file is pushed to CloudWatch Logs, based on file modification time. We recommend that you use wild card characters to specify a series of files of the same type, such as access_log.2014-06-01-01, access_log.2014-06-01-02, and so on by using a pattern like access_log.*. Don't use a wildcard to match multiple file types, such as access_log_80 and access_log_443. To specify multiple, different file types, add another log stream entry to the configuration file, so that each log file type is stored in a different log group.

Zipped files are not supported.

FileFingerprintLines => Str

  Specifies the range of lines for identifying a file. The valid values
are one number, or two dash-delimited numbers, such as '1', '2-5'. The
default value is '1', meaning the first line is used to calculate the
fingerprint. Fingerprint lines are not sent to CloudWatch Logs unless
all specified lines are available.

InitialPosition => Str

  Specifies where to start to read data (start_of_file or end_of_file).
The default is start_of_file. This setting is only used if there is no
state persisted for that log stream.

LogGroupName => Str

  Specifies the destination log group. A log group is created
automatically if it doesn't already exist. Log group names can be
between 1 and 512 characters long. Allowed characters include a-z, A-Z,
0-9, '_' (underscore), '-' (hyphen), '/' (forward slash), and '.'

MultiLineStartPattern => Str

  Specifies the pattern for identifying the start of a log message.

TimeZone => Str

  Specifies the time zone of log event time stamps.
