+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
+
