# CLOUD AWS RDS DataDog monitors

## How to use this module

```
module "datadog-monitors-cloud-aws-rds" {
  source = "git::ssh://git@bitbucket.org/morea/terraform.feature.datadog.git//cloud/aws/rds?ref={revision}"

  environment = "${var.environment}"
  message     = "${module.datadog-message-alerting.alerting-message}"
}

```

## Purpose

Creates DataDog monitors with the following checks:

- RDS instance CPU high
- RDS instance free space
