# CLOUD GCP GCE INSTANCE DataDog monitors

## How to use this module

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

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

```

## Purpose

Creates DataDog monitors with the following checks:

- Compute Engine instance CPU Utilization
- Compute Engine instance Disk Throttled Bps
- Compute Engine instance Disk Throttled OPS
