+  Get information of a Dashboard Grafana.
+---
+
+# Data Source: azurerm_dashboard_grafana
+
+Use this data to access information about an existing Dashboard Grafana.
+
+## Example Usage
+
+```hcl
+data "azurerm_dashboard_grafana" "example" {
+  name                = "example-dg"
+  resource_group_name = "example-resources"
+}
+```
+
+## Arguments Reference
+
+The following arguments are supported:
+
+- `name` - (Required) The name of the Grafana dashboard.
+
+- `resource_group_name` - (Required) The name of the resource group in which the Grafana dashboard is located.
+
+## Attributes Reference
+
+In addition to the Arguments listed above - the following Attributes are exported:
+
+- `api_key_enabled` - Whether the api key setting of the Grafana instance is enabled.
+
+- `auto_generated_domain_name_label_scope` - Scope for dns deterministic name hash calculation. 
+
+- `deterministic_outbound_ip_enabled` - Whether the Grafana instance is enabled to use deterministic outbound IPs.
+
+- `azure_monitor_workspace_integrations` - A `azure_monitor_workspace_integrations` block as defined below.
+
+- `location` - The Azure Region where the Grafana dashboard is located.
+
+- `public_network_access_enabled` - Whether the Grafana instance is enabled to use public network access.
+
+- `sku` - The SKU of the Grafana instance.
+
+- `zone_redundancy_enabled` - Whether the Grafana instance is enabled to use zone redundancy.
+
+- `endpoint` - The endpoint of the Grafana instance.
+
+- `grafana_major_version` - The major version of Grafana deployed.
+
+- `grafana_version` - The full Grafana software semantic version deployed.
+
+- `outbound_ip` - List of outbound IPs if deterministicOutboundIP is enabled.
+
+- `tags` - A mapping of tags assigned to the resource.
+
+---
+
+A `azure_monitor_workspace_integrations` block exports the following:
+
+- `resource_id` - The resource ID of the connected Azure Monitor Workspace.
+
+## Timeouts
+
+The `timeouts` block allows you to specify [timeouts](https://www.terraform.io/docs/configuration/resources.html#timeouts) for certain actions:
+
+- `read` - (Defaults to 5 minutes) Used when retrieving the Dashboard Grafana.
