## Overview

Coralogix offers RDS enhanced monitoring, an extension to AWS metrics from CloudWatch using the [Amazon RDS API](https://docs.aws.amazon.com/AmazonRDS/latest/APIReference/API_Operations.html) to collect tags and additional metrics.

This approach saves some calls to `resroucegrouptagging` API and adds all the new metrics that are specified in this document under [Collected data](#collected-data).

## Prerequisites

- [AWS Metrics from CloudWatch](https://coralogix.com/docs/integrations/aws/aws-cloudwatch/aws-metrics-via-cloudwatch/index.md) integration
- Policy permissions used for this integration:
- `rds:Describe*`
- `rds:List*`
- `ec2:DescribeInstanceTypes` for getting instance memory and number of cpus

## Configuration

- `RdsEnhancedMonitoring` toggle in the [AWS Metrics from CloudWatch](https://coralogix.com/docs/integrations/aws/aws-cloudwatch/aws-metrics-via-cloudwatch/index.md) integration configuration
