Determining the Status of Your Spot Instances - Leveraging Amazon EC2 Spot Instances at Scale

Determining the Status of Your Spot Instances

By reviewing Spot status, you can see why your Spot requests state has or has not changed, and you can learn how to optimize your Spot requests to get them fulfilled. To find the Spot status, you can use the DescribeSpotInstanceRequests API action or the describe-spot-instance-requests using the AWS Command Line Interface (CLI).

The AWS Management Console makes a detailed billing report available, which shows Spot Instance start and termination times for all instances. You can check the billing report against historical Spot prices via the API to verify that the Spot price billed was correct.
