Network.AWS.ElastiCache.DescribeReservedCacheNodes

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

This operation returns paginated results.

Creating a Request

describeReservedCacheNodes :: DescribeReservedCacheNodes

Creates a value of DescribeReservedCacheNodes with the minimum fields required to make a request.

Use one of the following lenses to modify other fields as desired:

• drcnCacheNodeType - 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: T2 node types: cache.t2.micro , cache.t2.small , cache.t2.medium M3 node types: cache.m3.medium , cache.m3.large , cache.m3.xlarge , cache.m3.2xlarge M4 node types: cache.m4.large , cache.m4.xlarge , cache.m4.2xlarge , cache.m4.4xlarge , cache.m4.10xlarge * Previous generation: (not recommended) T1 node types: cache.t1.micro M1 node types: cache.m1.small , cache.m1.medium , cache.m1.large , cache.m1.xlarge * Compute optimized: * Previous generation: (not recommended) C1 node types: cache.c1.xlarge * Memory optimized: * Current generation: R3 node types: cache.r3.large , cache.r3.xlarge , cache.r3.2xlarge , cache.r3.4xlarge , cache.r3.8xlarge * Previous generation: (not recommended) M2 node types: cache.m2.xlarge , cache.m2.2xlarge , cache.m2.4xlarge Notes: * All T2 instances are created in an Amazon Virtual Private Cloud (Amazon VPC). * Redis (cluster mode disabled): Redis backuprestore is not supported on T1 and T2 instances. * Redis (cluster mode enabled): Backuprestore is not supported on T1 instances. * Redis Append-only files (AOF) functionality is not supported for T1 or T2 instances. For a complete listing of node types and specifications, see Amazon ElastiCache Product Features and Details and either Cache Node Type-Specific Parameters for Memcached or Cache Node Type-Specific Parameters for Redis .
• drcnProductDescription - The product description filter value. Use this parameter to show only those reservations matching the specified product description.
• drcnMarker - 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 .
• drcnMaxRecords - 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: 100 Constraints: minimum 20; maximum 100.
• drcnReservedCacheNodeId - The reserved cache node identifier filter value. Use this parameter to show only the reservation that matches the specified reservation ID.
• drcnOfferingType - 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"
• drcnDuration - 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
• drcnReservedCacheNodesOfferingId - The offering identifier filter value. Use this parameter to show only purchased reservations matching the specified offering identifier.
