# CLOUD AWS ELASTICACHE COMMON DataDog monitors

## How to use this module

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

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

```

## Purpose

Creates DataDog monitors with the following checks:

- Elasticache connections
- Elasticache eviction
- Elasticache evictions is growing
- Elasticache free memory
- Elasticache max connections reached
- Elasticache swap

## Requirements

No requirements.
