Sending protection pack or web ACL traffic logs to an Amazon Data Firehose delivery stream

This section provides information for sending your protection pack or web ACL traffic logs to an Amazon Data Firehose delivery stream.

Note

You are charged for logging in addition to the charges for using Amazon WAF. For information, see Pricing for logging protection pack or web ACL traffic information.

To send logs to Amazon Data Firehose, you send logs from your protection pack or web ACL to an Amazon Data Firehose delivery stream which you configure in Firehose. After you enable logging, Amazon WAF delivers logs to your storage destination through the HTTPS endpoint of Firehose.

One Amazon WAF log is equivalent to one Firehose record. If you typically receive 10,000 requests per second and you enable full logs, you should have a 10,000 records per second setting in Firehose. If you don't configure Firehose correctly, Amazon WAF won't record all logs. For more information, see Amazon Kinesis Data Firehose quotas.

For information about how to create an Amazon Data Firehose delivery stream and review your stored logs, see What is Amazon Data Firehose?

For information about creating your delivery stream, see Creating an Amazon Data Firehose delivery stream.

Configuring an Amazon Data Firehose delivery stream for your protection pack or web ACL

Configure an Amazon Data Firehose delivery stream for your protection pack or web ACL as follows.

  • Create it using the same account as you use to manage the protection pack or web ACL.

  • Create it in the same Region as the protection pack or web ACL. If you are capturing logs for Amazon CloudFront, create the firehose in US East (N. Virginia) Region, us-east-1.

  • Give the data firehose a name that starts with the prefix aws-waf-logs-. For example, aws-waf-logs-us-east-2-analytics.

  • Configure it for direct put, which allows applications to access the delivery stream directly. In the Amazon Data Firehose console, for the delivery stream Source setting, choose Direct PUT or other sources. Through the API, set the delivery stream property DeliveryStreamType to DirectPut.

    Note

    Do not use a Kinesis stream as your source.
