Amazon EC2 Spot Instances let you take advantage of unused EC2 capacity in the AWS cloud.
Spot Instances is used for various stateless, fault-tolerant, or flexible applications such as:
- Big data
- Containerized workloads
- CI/CD
- Web servers
- High-performance computing (HPC)
- Other test and development workloads
You can:
- Choose how to launch and maintain your applications running on Spot Instances. This is because Spot Instances are tightly integrated with AWS services such as Auto Scaling, EMR, ECS, CloudFormation, Data Pipeline, and AWS Batch.
- Combine Spot Instances with On-Demand and RIs to further optimize workload cost with performance. Due to the operating scale of AWS, Spot Instances can offer the scale and cost savings to run hyper-scale workloads.
- Hibernate, stop or terminate your Spot Instances when EC2 reclaims the capacity back with two-minutes of notice.
Use the AWS public cloud integration to discover and collect metrics against the AWS service.

Supported metrics
| OpsRamp Metric | Metric Display Name | Unit | Aggregation Type |
|---|---|---|---|
| aws_ec2spot_AvailableInstancePoolsCount The Spot Instance pools specified in the Spot Fleet request. | AvailableInstancePoolsCount | Count | Average |
| aws_ec2spot_BidsSubmittedForCapacity The Spot Instance pools specified in the Spot Fleet request. | BidsSubmittedForCapacity | Count | Average |
| aws_ec2spot_EligibleInstancePoolCount The Spot Instance pools specified in the Spot Fleet request where Amazon EC2 can fulfill bids. Amazon EC2 does not fulfill bids in pools where your bid price is less than the Spot price or the Spot price is greater than the price for On-Demand Instances. | EligibleInstancePoolCount | Count | Average |
| aws_ec2spot_FulfilledCapacity The capacity that Amazon EC2 has fulfilled. | FulfilledCapacity | Count | Average |
| aws_ec2spot_MaxPercentCapacityAllocation Maximum value of PercentCapacityAllocation across all Spot Fleet pools specified in the Spot Fleet request. | MaxPercentCapacityAllocation | Percent | Maximum |
| aws_ec2spot_PendingCapacity The difference between TargetCapacity and FulfilledCapacity. | PendingCapacity | Count | Average |
| aws_ec2spot_PercentCapacityAllocation Capacity allocated for the Spot Instance pool for the specified dimensions. To get the maximum value recorded across all Spot Instance pools, use MaxPercentCapacityAllocation. | PercentCapacityAllocation | Percent | Average |
| aws_ec2spot_TargetCapacity Target capacity of the Spot Fleet request. | TargetCapacity | Count | Average |
| aws_ec2spot_TerminatingCapacity The capacity that is being terminated due to Spot Instance interruptions. | TerminatingCapacity | Count | Average |
