Burst Bucket Metric Now Available for Amazon EBS General Purpose SSD (gp2) Volumes
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.
