# InstanceInformationFilter
<a name="API_InstanceInformationFilter"></a>

Describes a filter for a specific list of managed nodes. You can filter node information by using tags. You specify tags by using a key-value mapping.

Use this operation instead of the [DescribeInstanceInformation:InstanceInformationFilterList](API_DescribeInstanceInformation.md#systemsmanager-DescribeInstanceInformation-request-InstanceInformationFilterList) method. The `InstanceInformationFilterList` method is a legacy method and doesn't support tags.
