Understanding and monitoring latency for Amazon EBS volumes using Amazon CloudWatch

This article discusses how to monitor and understand latency for Amazon EBS volumes using Amazon CloudWatch, focusing on new performance metrics for ensuring application reliability and performance.

• New CloudWatch metrics provide one-minute granularity for EBS volume performance monitoring
• Metrics cover IOPS, throughput, read/write latency, and performance limit checks
• Demonstrated two scenarios of volume performance monitoring:
  • Normal performance with low latency
  • Degraded performance when exceeding provisioned IOPS/throughput limits
• Users can create CloudWatch alarms to detect and respond to performance issues
• Supports various EBS volume types, including io2 Block Express and gp3

The metrics help users identify performance bottlenecks, right-size resources, and ensure application reliability by providing detailed insights into EBS volume performance.
