# CLOUD GCP MEMORYSTORE REDIS DataDog monitors

## How to use this module

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

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

```

## Purpose

Creates DataDog monitors with the following checks:

- Memorystore Redis system memory usage ratio
