+Azure Cosmos DB DataDog monitors
+================================
+
+How to use this module
+----------------------
+
+```
+module "datadog-monitors-azure-cosmosdb" {
+  source = "git::ssh://git@bitbucket.org/morea/terraform.feature.datadog.git//cloud/azure/cosmosdb?ref={revision}"
+
+  message = "${module.datadog-message-alerting.alerting-message}"
+  environment = "${var.environment}"
+}
+```
+
+Purpose
+-------
+Creates a DataDog monitors with the following checks :
+
+* No request
+* Too many 4xx requests
+* Too many 5xx requests
