# CLOUD GCP LB DataDog monitors

## How to use this module

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

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

```

## Purpose

Creates DataDog monitors with the following checks:

- GCP LB 4xx errors
- GCP LB 5xx errors
- GCP LB bucket backend latency
- GCP LB Requests count increased abruptly
- GCP LB service backend latency
