# CLOUD AWS ELB DataDog monitors
|
|
|
|
## How to use this module
|
|
|
|
```
|
|
module "datadog-monitors-cloud-aws-elb" {
|
|
source = "git::ssh://git@github.com/claranet/terraform-datadog-monitors.git//cloud/aws/elb?ref={revision}"
|
|
|
|
environment = var.environment
|
|
message = module.datadog-message-alerting.alerting-message
|
|
}
|
|
|
|
```
|
|
|
|
## Purpose
|
|
|
|
Creates DataDog monitors with the following checks:
|
|
|
|
- ELB 4xx errors too high
|
|
- ELB 5xx errors too high
|
|
- ELB backend 4xx errors too high
|
|
- ELB backend 5xx errors too high
|
|
- ELB healthy instances
|
|
- ELB latency too high
|
|
|
|
