# CLOUD GCP LB DataDog monitors
|
|
|
|
## How to use this module
|
|
|
|
```
|
|
module "datadog-monitors-cloud-gcp-lb" {
|
|
source = "git::ssh://git@git.fr.clara.net/claranet/pt-monitoring/projects/datadog/terraform/monitors.git//cloud/gcp/lb?ref={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
|
|
|
|
