# CLOUD AZURE EVENTGRID DataDog monitors

## How to use this module

```hcl
module "datadog-monitors-cloud-azure-eventgrid" {
  source      = "claranet/monitors/datadog//cloud/azure/eventgrid"
  version     = "{revision}"

  environment = var.environment
  message     = module.datadog-message-alerting.alerting-message
}

```

## Purpose

Creates DataDog monitors with the following checks:

- Event Grid no successful message
- Event Grid too many failed messages
- Event Grid too many unmatched events
