- `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.

- `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.

  description = <<DESCRIPTION
A map of role assignments to create on the <RESOURCE>. The map key is deliberately arbitrary to avoid issues where map keys maybe unknown at plan time.

- `role_definition_id_or_name` - The ID or name of the role definition to assign to the principal.
- `principal_id` - The ID of the principal to assign the role to.
- `description` - (Optional) The description of the role assignment.
- `skip_service_principal_aad_check` - (Optional) If set to true, skips the Azure Active Directory check for the service principal in the tenant. Defaults to false.
- `condition` - (Optional) The condition which will be used to scope the role assignment.
- `condition_version` - (Optional) The version of the condition syntax. Leave as `null` if you are not using a condition, if you are then valid values are '2.0'.
- `delegated_managed_identity_resource_id` - (Optional) The delegated Azure Resource Id which contains a Managed Identity. Changing this forces a new resource to be created. This field is only used in cross-tenant scenario.
- `principal_type` - (Optional) The type of the `principal_id`. Possible values are `User`, `Group` and `ServicePrincipal`. It is necessary to explicitly set this attribute when creating role assignments if the principal creating the assignment is constrained by ABAC rules that filters on the PrincipalType attribute.

> Note: only set `skip_service_principal_aad_check` to true if you are assigning a role to a service principal.
