# CLOUD AZURE MYSQL DataDog monitors

## How to use this module

```
module "datadog-monitors-cloud-azure-mysql" {
  source = "git::ssh://git@git.fr.clara.net/claranet/cloudnative/projects/datadog/terraform/monitors.git//cloud/azure/mysql?ref={revision}"

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

```

## Purpose

Creates DataDog monitors with the following checks:

- Mysql Server CPU usage
- Mysql Server has total connection
- Mysql Server IO consumption
- Mysql Server memory usage
- Mysql Server storage
