## Overview{% #overview %}

[Alibaba Cloud NAT Gateway](https://www.alibabacloud.com/product/nat-gateway) is an enterprise-class gateway that provides Network Address Translation (NAT) services for Virtual Private Clouds (VPCs). It supports SNAT and DNAT, allowing instances within a VPC to access or be accessed from the internet without exposing private IP addresses.

This integration allows you to monitor and alert on SNAT connection usage and rate-limit drops for your NAT gateways by collecting metrics from the `alibabacloud.nat_gateway` namespace.

## Setup{% #setup %}

### Installation{% #installation %}

After you set up the [Alibaba Cloud](https://docs.datadoghq.com/integrations/alibaba_cloud.md) integration, metrics for NAT Gateway are collected automatically.

## Data Collected{% #data-collected %}
