# CLOUD AWS ELASTICACHE MEMCACHED DataDog monitors

## How to use this module

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

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

```

## Purpose

Creates DataDog monitors with the following checks:

- Elasticache memcached cache hit ratio
- Elasticache memcached CPU
