  description = <<DESCRIPTION
  A map of diagnostic settings to create on the Firewall. The map key is deliberately arbitrary to avoid issues where map keys maybe unknown at plan time.

  - `name` - (Optional) The name of the diagnostic setting. One will be generated if not set, however this will not be unique if you want to create multiple diagnostic setting resources.
  - `log_categories` - (Optional) A set of log categories to send to the log analytics workspace. Defaults to `[]`.
  - `log_groups` - (Optional) A set of log groups to send to the log analytics workspace. Defaults to `["allLogs"]`.
  - `metric_categories` - (Optional) A set of metric categories to send to the log analytics workspace. Defaults to `["AllMetrics"]`.
  - `log_analytics_destination_type` - (Optional) The destination type for the diagnostic setting. Possible values are `Dedicated` and `AzureDiagnostics`. Defaults to `Dedicated`.
  - `workspace_resource_id` - (Optional) The resource ID of the log analytics workspace to send logs and metrics to.
  - `storage_account_resource_id` - (Optional) The resource ID of the storage account to send logs and metrics to.
  - `event_hub_authorization_rule_resource_id` - (Optional) The resource ID of the event hub authorization rule to send logs and metrics to.
  - `event_hub_name` - (Optional) The name of the event hub. If none is specified, the default event hub will be selected.
  - `marketplace_partner_resource_id` - (Optional) The full ARM resource ID of the Marketplace resource to which you would like to send Diagnostic LogsLogs.
