-- | Defines an association between logging destinations and a web ACL
-- resource, for logging from WAF. As part of the association, you can
-- specify parts of the standard logging fields to keep out of the logs and
-- you can specify filters so that you log only a subset of the logging
-- records.
--
-- You can define one logging destination per web ACL.
--
-- You can access information about the traffic that WAF inspects using the
-- following steps:
--
-- 1.  Create your logging destination. You can use an Amazon CloudWatch
--     Logs log group, an Amazon Simple Storage Service (Amazon S3) bucket,
--     or an Amazon Kinesis Data Firehose.
--
--     The name that you give the destination must start with
--     @aws-waf-logs-@. Depending on the type of destination, you might
--     need to configure additional settings or permissions.
--
--     For configuration requirements and pricing information for each
--     destination type, see
--     <https://docs.aws.amazon.com/waf/latest/developerguide/logging.html Logging web ACL traffic>
--     in the /WAF Developer Guide/.
--
-- 2.  Associate your logging destination to your web ACL using a
--     @PutLoggingConfiguration@ request.
--
-- When you successfully enable logging using a @PutLoggingConfiguration@
-- request, WAF creates an additional role or policy that is required to
-- write logs to the logging destination. For an Amazon CloudWatch Logs log
-- group, WAF creates a resource policy on the log group. For an Amazon S3
-- bucket, WAF creates a bucket policy. For an Amazon Kinesis Data
-- Firehose, WAF creates a service-linked role.
--
-- For additional information about web ACL logging, see
-- <https://docs.aws.amazon.com/waf/latest/developerguide/logging.html Logging web ACL traffic information>
-- in the /WAF Developer Guide/.
