# 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
