+
+# Data Source: vra_load_balancer
+
+Provides a data source to retrieve a `vra_load_balancer`.
+
+## Example Usage
+
+This is an example of how to get a load balancer resource by its id.
+
+```hcl
+data "vra_load_balancer" "this" {
+  id = "load-balancer-id"
+}
+
+output "load_balancer_name" {
+  value = data.vra_load_balancer.this.name
+}
+
+## Argument Reference
+
+* `id` - (Required) The id of the load balancer.
+
+## Attribute Reference
+
+* `address` - Primary address allocated or in use by this load balancer. The address could be an in the form of a publicly resolvable DNS name or an IP address.
+
+* `created_at` - Date when the entity was created. The date is in ISO 6801 and UTC.
+
+* `custom_properties` - A set of custom properties that were set on this resource instance. This is a key-value pair where the key is a string and the value can be any string.
+
+* `description` - Description of the load balancer.
+
+* `deployment_id` - The id of the deployment that is associated with this resource.
+
+* `external_id` - External entity Id on the provider side.
+
+* `external_region_id` - The external regionId of the resource.
+
+* `external_zone_id` - The external regionId of the resource.
+
+* `links` - HATEOAS of the entity.
+
+* `name` - Name of the load balancer.
+
+* `organization_id` - The id of the organization this entity belongs to.
+
+* `owner` - Email of the user that owns the entity.
+
+* `project_id` - The id of the project that is associated with this resource.
+
+* `routes` - The load balancer route configuration regarding ports and protocols.
+
+    * `algorithm` - Algorithm employed for load balancing.
+
+    * `algorithm_parameters` - Parameters need for load balancing algorithm.Use newline to separate multiple parameters.
+
+    * `health_check_configuration` - Load balancer health check configuration.
+
+        * `healthy_threshold` - Number of consecutive successful checks before considering a particular back-end instance as healthy.
+
+        * `http_method` - HTTP or HTTPS method to use when sending a health check request.
+
+        * `interval_seconds` - Interval (in seconds) at which the health checks will be performed.
+
+        * `passive_monitor` - Enable passive monitor mode. This setting only applies to NSX-T.
+
+        * `port` - Port on the back-end instance machine to use for the health check.
+
+        * `protocol` - The protocol used for the health check.
+
+        * `request_body` - Request body. Used by HTTP, HTTPS, TCP, UDP.
+
+        * `response_body` - Expected response body. Used by HTTP, HTTPS, TCP, UDP.
+
+        * `timeout_seconds` - Timeout (in seconds) to wait for a response from the back-end instance.
+
+        * `unhealthy_threashold` - Number of consecutive check failures before considering a particular back-end instance as unhealthy.
+
+        * `urlPath` - URL path on the back-end instance against which a request will be performed for the health check. Useful when the health check protocol is HTTP/HTTPS.
+
+    * `member_port` - Member port where the traffic is routed to.
+
+    * `member_protocol` - The protocol of the member traffic.
+
+    * `port` - Port which the load balancer is listening to.
+
+    * `protocol` - The protocol of the incoming load balancer requests.
+
+* `targets` - A list of links to target load balancer pool members. Links can be to either a machine or a machine's network interface.
+
+* `tags` - A set of tag keys and optional values that were set on this resource instance.
+  * `key` - Tag’s key.
+  * `value` - Tag’s value.
+
+* `updated_at` - Date when the entity was last updated. The date is ISO 8601 and UTC.
