EC2 Capacity Manager now includes Spot interruption metrics

Today, AWS announces new Spot interruption metrics for Amazon EC2 Capacity Manager that allow you to better understand Spot capacity across your organization. EC2 Capacity Manager helps you monitor, analyze, and manage your EC2 capacity across On-Demand, Spot, and Capacity Reservations from a single location. With this new capability, you can now track how many Spot instances are running, monitor interruption counts, and calculate interruption rates across regions, availability zones, and accounts. This enables you to make data-driven decisions about your Spot instance strategy.

EC2 Capacity Manager now includes three new metrics: ‘Spot Total Count’, ‘Spot Total Interruptions’, and ‘Spot Interruption Rate. ‘Spot Total Count’ shows the total number of distinct Spot instances or vCPUs that ran during a selected period, ‘Spot Total Interruptions’ tracks how many were interrupted, and ‘Spot Interruption Rate’ calculates the percentage of running instances that experienced interruptions. This data helps you identify patterns, compare across different regions and availability zones, and optimize your Spot instance strategy by diversifying instance types, expanding across availability zones, or using Spot placement score to identify optimal capacity pools with higher availability.

EC2 Capacity Manager with Spot interruption metrics is available in all commercial AWS Regions enabled by default at no additional cost.
