Azure IOT Hubs DataDog monitors
============================

How to use this module
----------------------

```
module "iothubs" {
  source = "git::ssh://git@bitbucket.org/morea/terraform.feature.datadog.git//cloud/azure/iothubs?ref=MON-80-azure-hub-iot-monitors"
  
  message         = "${module.datadog-message-alerting.alerting-message}"
   
  environment     = "${var.environment}"
  stack           = "${var.stack}"
  client_name     = "${var.client_name}"
  subscription_id = "${var.subscription_id}"
}
```

Purpose
-------
Creates a DataDog monitors with the following checks :

* Service status check
* Jobs failed average check
* Query Jobs failed average check
* List Jobs failed average check
* Total devices count check
* C2D methods failed average check
* C2D twin read failed average check
* C2D twin update failed average check
* D2C twin read failed average check
* D2C twin update failed average check
* D2C telemetry egress dropped count check
* D2C telemetry egress orphaned count check
* D2C telemetry egress invalid count check
* D2C telemetry egress fallback count check
* D2C telemetry ingress no sent count check
