Amazon EC2 provides Amazon CloudWatch metrics that you can use to monitor your Spot Fleet.

Important

To ensure accuracy, we recommend that you enable detailed monitoring when using these metrics. For more information, see Enable or Disable Detailed Monitoring for Your Instances.

For more information about CloudWatch metrics provided by Amazon EC2, see Monitoring Your Instances Using CloudWatch.

Spot Fleet Metrics

The AWS/EC2Spot namespace includes the following metrics, plus the CloudWatch metrics for the Spot Instances in your fleet. For more information, see Instance Metrics.

The AWS/EC2Spot namespace includes the following metrics.

Metric Description

AvailableInstancePoolsCount

The Spot Instance pools specified in the Spot Fleet request.

Units: Count

BidsSubmittedForCapacity

The capacity for which Amazon EC2 has submitted bids.

Units: Count

EligibleInstancePoolCount

Units: Count

FulfilledCapacity

The capacity that Amazon EC2 has fulfilled.

Units: Count

MaxPercentCapacityAllocation

The maximum value of PercentCapacityAllocation across all Spot Instance pools specified in the Spot Fleet request.

Units: Percent

PendingCapacity

The difference between TargetCapacity and FulfilledCapacity.

Units: Count

PercentCapacityAllocation

The capacity allocated for the Spot Instance pool for the specified dimensions. To get the maximum value recorded across all Spot Instance pools, use MaxPercentCapacityAllocation.

Units: Percent

TargetCapacity

The target capacity of the Spot Fleet request.

Units: Count

TerminatingCapacity

The capacity that is being terminated due to Spot Instance interruptions.

Units: Count

If the unit of measure for a metric is Count, the most useful statistic is Average.

Spot Fleet Dimensions

To filter the data for your Spot Fleet, you can use the following dimensions.

Dimensions Description

AvailabilityZone

Filter the data by Availability Zone.

FleetRequestId

Filter the data by Spot Fleet request.

InstanceType

Filter the data by instance type.

View the CloudWatch Metrics for Your Spot Fleet

You can view the CloudWatch metrics for your Spot Fleet using the Amazon CloudWatch console. These metrics are displayed as monitoring graphs. These graphs show data points if the Spot Fleet is active.

Metrics are grouped first by namespace, and then by the various combinations of dimensions within each namespace. For example, you can view all Spot Fleet metrics or Spot Fleet metrics groups by Spot Fleet request ID, instance type, or Availability Zone.

To view Spot Fleet metrics

  1. Open the CloudWatch console at https://console.aws.amazon.com/cloudwatch/.

  2. In the navigation pane, under Metrics, choose the EC2 Spot namespace.

  3. (Optional) To filter the metrics by dimension, select one of the following:

    • Fleet Request Metrics — Group by Spot Fleet request

    • By Availability Zone — Group by Spot Fleet request and Availability Zone

    • By Instance Type — Group by Spot Fleet request and instance type

    • By Availability Zone/Instance Type — Group by Spot Fleet request, Availability Zone, and instance type

  4. To view the data for a metric, select the check box next to the metric.
