New Spot Interruption Metrics for EC2 Capacity Manager

AWS has introduced new Spot interruption metrics for Amazon EC2 Capacity Manager, enabling better understanding of Spot capacity across your organization. This feature allows you to monitor, analyze, and manage your EC2 capacity from a single location, including On-Demand, Spot, and Capacity Reservations.

New Metrics

  • Spot Usage Total Count: Total number of distinct Spot instances or vCPUs that ran during a selected period.
  • Spot Total Interruptions: Number of Spot instances that were interrupted.
  • Spot Interruption Rate: Percentage of running instances that experienced interruptions.

These metrics help you make data-driven decisions about your Spot instance strategy by identifying patterns, comparing across regions and availability zones, and optimizing your strategy through diversification and placement scores.

What to do

  • Monitor new metrics in the AWS console.
  • Analyze data to identify patterns and optimize your Spot instance strategy.
  • Visit EC2 Capacity Manager in the AWS console to get started.
