AWS ALB DataDog monitors

How to use this module

module "datadog-monitors-aws-alb" {
  source = "git::ssh://git@bitbucket.org/morea/terraform.feature.datadog.git//cloud/aws/alb?ref={revision}"

  environment = "${var.environment}"
  message = "${module.datadog-message-alerting.alerting-message}"
}

Purpose

Creates DataDog monitors with the following checks :

• ALB no healthy hosts
• ALB latency too high
• ALB http code 5xx percent to high
• ALB http code 4xx percent to high
• ALB target http code 5xx percent to high
• ALB target http code 4xx percent to high
