You can now monitor the burst-bucket performance and ensure you have the right volume size for Amazon EBS General Purpose SSD (gp2) volumes using Amazon CloudWatch. Amazon EBS gp2 volumes have the ability to burst to 3,000 IOPS for extended periods of time for workloads that need to burst beyond the baseline performance. Amazon EBS now publishes the Burst Balance metric into Amazon CloudWatch for all gp2 volumes. The vast majority of customers have sufficient burst for their workloads. However, if visibility into the Burst Balance is desired, you now have the ability to monitor and take appropriate action. You can automate Burst Balance monitoring by creating a CloudWatch alarm that notifies you when the Burst Balance falls below a user-specified threshold.

The Burst Balance metric is available to all Amazon EBS customers at no additional cost. CloudWatch alarming is billed at standard CloudWatch rates.

For more information on using Amazon EBS General Purpose SSD (gp2) volumes, please refer to the EBS product documentation. To learn how to get started monitoring your Burst Balance and setting alarms via CloudWatch, please consult the CloudWatch documentation
