Table: aws_vpc_nat_gateway_metric_bytes_out_to_destination - Query AWS CloudWatch NAT Gateway Metrics using SQL

The AWS NAT Gateway is a service that enables instances in a private subnet to connect to the internet or other AWS services, but prevents the internet from initiating a connection with those instances. It offers high availability and bandwidth, allowing you to operate your workloads with predictable and reliable connectivity. The CloudWatch NAT Gateway Metrics provides detailed monitoring for the data processed by the NAT gateway.

Table Usage Guide

The aws_vpc_nat_gateway_metric_bytes_out_to_destination table in Steampipe provides you with information about the NAT Gateway metrics within AWS CloudWatch. This table allows you, as a DevOps engineer, to query the number of bytes sent out to the destination per NAT gateway in a VPC. You can utilize this table to gather insights on network traffic, such as the volume of data sent to the destination, to monitor the performance and health of the NAT Gateways. The schema outlines the various attributes of the NAT Gateway metrics, including the NAT Gateway ID, timestamp, region, and associated tags.

The aws_vpc_nat_gateway_metric_bytes_out_to_destination table provides you with metric statistics at 5 minute intervals for the most recent 5 days.

Examples

Basic info

Identify instances where the amount of data sent through your network gateway varies significantly. This allows you to analyze network traffic patterns and optimize your AWS VPC NAT gateway usage.

select
  nat_gateway_id,
  timestamp,
  minimum,
  maximum,
  average,
  sample_count
from
  aws_vpc_nat_gateway_metric_bytes_out_to_destination
order by
  nat_gateway_id,
  timestamp;

select
  nat_gateway_id,
  timestamp,
  minimum,
  maximum,
  average,
  sample_count
from
  aws_vpc_nat_gateway_metric_bytes_out_to_destination
order by
  nat_gateway_id,
  timestamp;

Show unused NAT gateways

Explore which NAT gateways within your AWS VPC are not being utilized. This is useful for identifying and eliminating unnecessary costs associated with maintaining unused resources.

select
  g.nat_gateway_id,
  vpc_id,
  subnet_id
from
  aws_vpc_nat_gateway as g
  left join aws_vpc_nat_gateway_metric_bytes_out_to_destination as d on g.nat_gateway_id = d.nat_gateway_id
group by
  g.nat_gateway_id,
  vpc_id,
  subnet_id
having
  sum(average) = 0;

Export

This table is available as a standalone Exporter CLI. Steampipe exporters are stand-alone binaries that allow you to extract data using Steampipe plugins without a database.

You can download the tarball for your platform from the Releases page, but it is simplest to install them with the steampipe_export_installer.sh script:

/bin/sh -c "$(curl -fsSL https://steampipe.io/install/export.sh)" -- aws

You can pass the configuration to the command with the --config argument:

steampipe_export_aws --config '<your_config>' aws_vpc_nat_gateway_metric_bytes_out_to_destination
