Description

Returns information about reserved cache nodes for this account, or about a specified reserved cache node.

This cmdlet automatically pages all available results to the pipeline - parameters related to iteration are only needed if you want to manually control the paginated output. To disable autopagination, use -NoAutoIteration.

Parameters

-CacheNodeType <String>
The cache node type filter value. Use this parameter to show only those reservations matching the specified cache node type.The following node types are supported by ElastiCache. Generally speaking, the current generation types provide more memory and computational power at lower cost when compared to their equivalent previous generation counterparts.
  • General purpose:
    • Current generation: M6g node types: (available only for Redis engine version 5.0.6 onward and for Memcached engine version 1.5.16 onward): cache.m6g.large, cache.m6g.xlarge, cache.m6g.2xlarge, cache.m6g.4xlarge, cache.m6g.8xlarge, cache.m6g.12xlarge, cache.m6g.16xlargeFor region availability, see Supported Node TypesM5 node types:cache.m5.large, cache.m5.xlarge, cache.m5.2xlarge, cache.m5.4xlarge, cache.m5.12xlarge, cache.m5.24xlargeM4 node types:cache.m4.large, cache.m4.xlarge, cache.m4.2xlarge, cache.m4.4xlarge, cache.m4.10xlargeT4g node types (available only for Redis engine version 5.0.6 onward and for Memcached engine version 1.5.16 onward): cache.t4g.micro, cache.t4g.small, cache.t4g.mediumT3 node types:cache.t3.micro, cache.t3.small, cache.t3.mediumT2 node types:cache.t2.micro, cache.t2.small, cache.t2.medium

Additional node type info
  • All current generation instance types are created in Amazon VPC by default.
  • Redis append-only files (AOF) are not supported for T1 or T2 instances.
  • Redis Multi-AZ with automatic failover is not supported on T1 instances.
  • Redis configuration variables appendonly and appendfsync are not supported on Redis version 2.8.22 and later.
Required?False

Accept pipeline input?True (ByPropertyName)
-Duration <String>
The duration filter value, specified in years or seconds. Use this parameter to show only reservations for this duration.Valid Values: 1 | 3 | 31536000 | 94608000
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Marker <String>
An optional marker returned from a prior request. Use this marker for pagination of results from this operation. If this parameter is specified, the response includes only records beyond the marker, up to the value specified by MaxRecords.
Note: This parameter is only used if you are manually controlling output pagination of the service API call.
In order to manually control output pagination, use '-Marker $null' for the first call and '-Marker $AWSHistory.LastServiceResponse.Marker' for subsequent calls.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesNextToken
-MaxRecord <Int32>
The maximum number of records to include in the response. If more records exist than the specified MaxRecords value, a marker is included in the response so that the remaining results can be retrieved.Default: 100Constraints: minimum 20; maximum 100.
Note: In AWSPowerShell and AWSPowerShell.NetCore this parameter is used to limit the total number of items returned by the cmdlet.
In AWS.Tools this parameter is simply passed to the service to specify how many items should be returned by each service call.
Pipe the output of this cmdlet into Select-Object -First to terminate retrieving data pages early and control the number of items returned.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesMaxItems, MaxRecords
-NoAutoIteration <SwitchParameter>
By default the cmdlet will auto-iterate and retrieve all results to the pipeline by performing multiple service calls. If set, the cmdlet will retrieve only the next 'page' of results using the value of Marker as the start point.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-OfferingType <String>
The offering type filter value. Use this parameter to show only the available offerings matching the specified offering type.Valid values: "Light Utilization"|"Medium Utilization"|"Heavy Utilization"|"All Upfront"|"Partial Upfront"| "No Upfront"
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-PassThru <SwitchParameter>
Changes the cmdlet behavior to return the value passed to the ReservedCacheNodeId parameter. The -PassThru parameter is deprecated, use -Select '^ReservedCacheNodeId' instead. This parameter will be removed in a future version.

Use the -Select parameter to control the cmdlet output. The default value is 'ReservedCacheNodes'. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.ElastiCache.Model.DescribeReservedCacheNodesResponse). Specifying the name of a property of type Amazon.ElastiCache.Model.DescribeReservedCacheNodesResponse will result in that property being returned.

Accept pipeline input?True (ByValue, ByPropertyName)
-EndpointUrl <String>
The endpoint to make the call against.Note: This parameter is primarily for internal AWS use and is not required/should not be specified for normal usage.

Position?Named
Accept pipeline input?True (ByPropertyName)
-NetworkCredential <PSCredential>

Used to specify the name and location of the ini-format credential file (shared with the AWS CLI and other AWS SDKs)If this optional parameter is omitted this cmdlet will search the encrypted credential file used by the AWS SDK for .NET and AWS Toolkit for Visual Studio first. If the profile is not found then the cmdlet will search in the ini-format credential file at the default location: (user's home directory)\.aws\credentials.If this parameter is specified then this cmdlet will only search the ini-format credential file at the location given.As the current folder can vary in a shell or during script execution it is advised that you use specify a fully qualified path instead of a relative path.

Outputs

Amazon.ElastiCache.Model.ReservedCacheNode or Amazon.ElastiCache.Model.DescribeReservedCacheNodesResponse
This cmdlet returns a collection of Amazon.ElastiCache.Model.ReservedCacheNode objects. The service call response (type Amazon.ElastiCache.Model.DescribeReservedCacheNodesResponse) can also be referenced from properties attached to the cmdlet entry in the $AWSHistory stack.
