# CLOUD AWS RDS COMMON DataDog monitors

## How to use this module

```
module "datadog-monitors-cloud-aws-rds-common" {
  source = "git::ssh://git@git.fr.clara.net/claranet/pt-monitoring/projects/datadog/terraform/monitors.git//cloud/aws/rds/common?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
