# DescribeDBInstances


Returns information about provisioned instances, and supports pagination.

**Note**  
This operation can also return information for Amazon RDS instances and Amazon DocDB instances.

## Request Parameters


 For information about the parameters that are common to all actions, see [Common Parameters](CommonParameters.md).

 ** DBInstanceIdentifier **   
The user-supplied instance identifier. If this parameter is specified, information from only the specific DB instance is returned. This parameter isn't case-sensitive.  
Constraints:  
+ If supplied, must match the identifier of an existing DBInstance.
Type: String  
Required: No

 **Filters.Filter.N**   
A filter that specifies one or more DB instances to describe.  
Supported filters:  
+  `db-cluster-id` - Accepts DB cluster identifiers and DB cluster Amazon Resource Names (ARNs). The results list will only include information about the DB instances associated with the DB clusters identified by these ARNs.
+  `engine` - Accepts an engine name (such as `neptune`), and restricts the results list to DB instances created by that engine.
For example, to invoke this API from the Amazon CLI and filter so that only Neptune DB instances are returned, you could use the following command:  
Type: Array of [Filter](API_Filter.md) objects  
Required: No

 ** Marker **   
 An optional pagination token provided by a previous `DescribeDBInstances` request. If this parameter is specified, the response includes only records beyond the marker, up to the value specified by `MaxRecords`.  
Type: String  
Required: No

 ** MaxRecords **   
 The maximum number of records to include in the response. If more records exist than the specified `MaxRecords` value, a pagination token called a marker is included in the response so that the remaining results can be retrieved.  
Default: 100  
Constraints: Minimum 20, maximum 100.  
Type: Integer  
Required: No

## Response Elements


The following elements are returned by the service.

 **DBInstances.DBInstance.N**

Type: Array of [DBInstance](API_DBInstance.md) objects

 ** Marker **   
 An optional pagination token provided by a previous request. If this parameter is specified, the response includes only records beyond the marker, up to the value specified by `MaxRecords` .  
Type: String
