Properties

Name	Type	Description
Filters	System.Collections.Generic.List<Amazon.EC2.Model.Filter>	Gets and sets the property Filters.

You can use the `` wildcard to match zero or more characters, or the `?` wildcard to match zero or one character. `zone-id` - The ID of the Availability Zone (for example, `usw2-az2`) or Local Zone (for example, `usw2-lax1-az1`) that the instance is in.
GroupNames	System.Collections.Generic.List<System.String>	Gets and sets the property GroupNames. The name of the placement group that each instance is in. Constraints: Maximum 100 explicitly specified placement group names.
InstanceIds	System.Collections.Generic.List<System.String>	Gets and sets the property InstanceIds. The instance IDs. Default: Describes all your instances. Constraints: Maximum 100 explicitly specified instance IDs.
MaxResults	System.Int32	Gets and sets the property MaxResults. The maximum number of items to return for this request. To get the next page of items, make another request with the token returned in the output. For more information, see Pagination. You can't specify this parameter and the instance IDs parameter in the same request. Default: `20`
