# CLOUD AWS ELASTICACHE MEMCACHED DataDog monitors

## How to use this module

```hcl
module "datadog-monitors-cloud-aws-elasticache-memcached" {
  source      = "claranet/monitors/datadog//cloud/aws/elasticache/memcached"
  version     = "{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
