+
+# Data Source: azurerm_eventhub
+
+Use this data source to access information about an existing EventHub.
+
+## Example Usage
+
+```hcl
+data "azurerm_eventhub" "example" {
+  name                = "search-eventhub"
+  resource_group_name = "search-service"
+  namespace_name      = "search-eventhubns"
+}
+
+output "eventhub_id" {
+  value = data.azurerm_eventhub.example.id
+}
+```
+
+## Arguments Reference
+
+The following arguments are supported:
+
+* `name` - (Required) The name of this EventHub.
+
+* `resource_group_name` - (Required) The name of the Resource Group where the EventHub exists.
+
+* `namespace_name` - (Required) The name of the EventHub Namespace where the EventHub exists.
+
+## Attributes Reference
+
+In addition to the Arguments listed above - the following Attributes are exported: 
+
+* `id` - The ID of the EventHub.
+
+* `partition_count` - The number of partitions in the EventHub.
+
+* `partition_ids` - The identifiers for the partitions of this EventHub.
+
+## 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 EventHub.
