.NET Framework 3.5
Container for the parameters to the DescribeSpotInstanceRequests operation. Describes the Spot instance requests that belong to your account. Spot instances are instances that Amazon EC2 launches when the bid price that you specify exceeds the current Spot price. Amazon EC2 periodically sets the Spot price based on available Spot instance capacity and current Spot instance requests. For more information, see Spot Instance Requests in the Amazon Elastic Compute Cloud User Guide.

You can use DescribeSpotInstanceRequests to find a running Spot instance by examining the response. If the status of the Spot instance is fulfilled, the instance ID appears in the response and contains the identifier of the instance. Alternatively, you can use DescribeInstances with a filter to look for instances where the instance lifecycle is spot.

The DescribeSpotInstanceRequestsRequest type exposes the following members



Public Property Filters System.Collections.Generic.List<Amazon.EC2.Model.Filter> Gets and sets the property Filters.

One or more filters.

  • availability-zone-group - The Availability Zone group.

  • create-time - The time stamp when the Spot instance request was created.

  • fault-code - The fault code related to the request.

  • fault-message - The fault message related to the request.

  • instance-id - The ID of the instance that fulfilled the request.

  • launch-group - The Spot instance launch group.

  • launch.block-device-mapping.delete-on-termination - Indicates whether the Amazon EBS volume is deleted on instance termination.

  • launch.block-device-mapping.device-name - The device name for the Amazon EBS volume (for example, /dev/sdh).

  • launch.block-device-mapping.snapshot-id - The ID of the snapshot used for the Amazon EBS volume.

  • launch.block-device-mapping.volume-size - The size of the Amazon EBS volume, in GiB.

  • launch.block-device-mapping.volume-type - The type of the Amazon EBS volume (gp2 | standard | io1).

  • - The security group for the instance.

  • launch.image-id - The ID of the AMI.

  • launch.instance-type - The type of instance (for example, m1.small).

  • launch.kernel-id - The kernel ID.

  • launch.key-name - The name of the key pair the instance launched with.

  • launch.monitoring-enabled - Whether monitoring is enabled for the Spot instance.

  • launch.ramdisk-id - The RAM disk ID.

  • - The ID of the network interface.

  • network-interface.device-index - The index of the device for the network interface attachment on the instance.

  • network-interface.subnet-id - The ID of the subnet for the instance.

  • network-interface.description - A description of the network interface.

  • network-interface.private-ip-address - The primary private IP address of the network interface.

  • network-interface.delete-on-termination - Indicates whether the network interface is deleted when the instance is terminated.

  • - The ID of the security group associated with the network interface.

  • - The name of the security group associated with the network interface.

  • network-interface.addresses.primary - Indicates whether the IP address is the primary private IP address.

  • product-description - The product description associated with the instance (Linux/UNIX | Windows).

  • spot-instance-request-id - The Spot instance request ID.

  • spot-price - The maximum hourly price for any Spot instance launched to fulfill the request.

  • state - The state of the Spot instance request (open | active | closed | cancelled | failed). Spot bid status information can help you track your Amazon EC2 Spot instance requests. For more information, see Spot Bid Status in the Amazon Elastic Compute Cloud User Guide.

  • status-code - The short code describing the most recent evaluation of your Spot instance request.

  • status-message - The message explaining the status of the Spot instance request.

  • tag:key=value - The key/value combination of a tag assigned to the resource.

  • tag-key - The key of a tag assigned to the resource. This filter is independent of the tag-value filter. For example, if you use both the filter "tag-key=Purpose" and the filter "tag-value=X", you get any resources assigned both the tag key Purpose (regardless of what the tag's value is), and the tag value X (regardless of what the tag's key is). If you want to list only resources where Purpose is X, see the tag:key=value filter.

  • tag-value - The value of a tag assigned to the resource. This filter is independent of the tag-key filter.

  • type - The type of Spot instance request (one-time | persistent).

  • launched-availability-zone - The Availability Zone in which the bid is launched.

  • valid-from - The start date of the request.

  • valid-until - The end date of the request.

Public Property SpotInstanceRequestIds System.Collections.Generic.List<System.String> Gets and sets the property SpotInstanceRequestIds.

One or more Spot instance request IDs.
