Warning
AWS WAF Classic support will end on September 30, 2025.
Note
This is AWS WAF Classic documentation. You should only use this version if you created AWS WAF resources, like rules and web ACLs, in AWS WAF prior to November 2019, and you have not migrated them over to the latest version yet. To migrate your web ACLs, see Migrating your AWS WAF Classic resources to AWS WAF.
For the latest version of AWS WAF, see AWS WAF.
Monitoring is an important part of maintaining the reliability, availability, and performance of AWS WAF Classic and your AWS solutions. You should collect monitoring data from all parts of your AWS solution so that you can more easily debug a multi-point failure if one occurs. AWS provides several tools for monitoring your AWS WAF Classic resources and responding to potential events:
- Amazon CloudWatch Alarms
Using CloudWatch alarms, you watch a single metric over a time period that you specify. If the metric exceeds a given threshold, CloudWatch sends a notification to an Amazon SNS topic or AWS Auto Scaling policy. For more information, see Monitoring with Amazon CloudWatch.
- AWS CloudTrail Logs
CloudTrail provides a record of actions taken by a user, role, or an AWS service in AWS WAF Classic. Using the information collected by CloudTrail, you can determine the request that was made to AWS WAF Classic, the IP address from which the request was made, who made the request, when it was made, and additional details. For more information, see Logging API calls with AWS CloudTrail.
