# CLOUD AWS ELASTICSEARCH DataDog monitors

## How to use this module

```hcl
module "datadog-monitors-cloud-aws-elasticsearch" {
  source      = "claranet/monitors/datadog//cloud/aws/elasticsearch"
  version     = "{revision}"

  environment = var.environment
  message     = module.datadog-message-alerting.alerting-message

  es_cluster_volume_size = 42
}

```

## Purpose

Creates DataDog monitors with the following checks:

- ElasticSearch cluster CPU high
- ElasticSearch cluster free storage space
- ElasticSearch cluster status is not green
