# 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
|
|
|
|
