# DescribePendingMaintenanceActions
<a name="API_DescribePendingMaintenanceActions"></a>

Returns a list of resources (for example, DB instances) that have at least one pending maintenance action.

This API follows an eventual consistency model. This means that the result of the `DescribePendingMaintenanceActions` command might not be immediately visible to all subsequent RDS commands. Keep this in mind when you use `DescribePendingMaintenanceActions` immediately after using a previous API command such as `ApplyPendingMaintenanceActions`.

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

 **Filters.Filter.N**   
A filter that specifies one or more resources to return pending maintenance actions for.  
Supported filters:  
+  `db-cluster-id` - Accepts DB cluster identifiers and DB cluster Amazon Resource Names (ARNs). The results list only includes pending maintenance actions for the DB clusters identified by these ARNs.

Type: Array of [Filter](API_Filter.md) objects  
Required: No

An optional pagination token provided by a previous `DescribePendingMaintenanceActions` request. If this parameter is specified, the response includes only records beyond the marker, up to a number of records 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 you can retrieve the remaining results.

Type: Integer  
Required: No
