How to use this module
module "datadog-monitors-cloud-aws-elb" {
source = "git::ssh://git@bitbucket.org/morea/terraform.feature.datadog.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 no healthy instances
- ELB 4xx errors too high
- ELB 5xx errors too high
- ELB backend 4xx errors too high
- ELB backend 5xx errors too high
- ELB latency too high
