# CLOUD AZURE REDIS DataDog monitors

## How to use this module

```
module "datadog-monitors-cloud-azure-redis" {
  source = "git::ssh://git@bitbucket.org/morea/terraform.feature.datadog.git//cloud/azure/redis?ref={revision}"

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

```

## Purpose

Creates DataDog monitors with the following checks :

- Redis {{name}} is down
- Redis too many evictedkeys
- Redis processor time too high
- Redis server load too high
