Uncover new performance insights using Amazon detailed performance statistics on Windows
Compute Blog
This article explains how to use detailed performance statistics for Amazon EBS and EC2 Instance Store on Windows environments to monitor storage performance in real-time.
- Access sub-minute granularity metrics for latency, throughput, and IOPS directly from NVMe devices using nvme_amzn.exe tool
- Identify unresponsive EBS volumes by monitoring Total Read/Write Ops and Queue Length changes over time intervals
- Detect performance bottlenecks when workloads exceed provisioned IOPS or throughput limits on volumes or instances
- Use IO histograms to identify which block sizes cause latency issues in mixed workloads
- Requires EC2 Nitro instances with AWS NVMe driver version 1.7.0 or later
These granular metrics enable proactive troubleshooting and optimization of storage configurations for latency-sensitive applications running on EC2.
