# CLOUD AZURE REDIS DataDog monitors

## How to use this module

```
module "datadog-monitors-cloud-azure-redis" {
  source = "claranet/monitors/datadog//cloud/azure/redis"
  version = "{revision}"

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

```

## Purpose

Creates DataDog monitors with the following checks:

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