-The `Upstream Servers` section defines a group of endpoints, referred to as nodes, which are used by output plugins to distribute data in a round-robin fashion. This is particularly useful for plugins that require load balancing when sending data. Examples of plugins that support this capability include [Forward](https://docs.fluentbit.io/manual/pipeline/outputs/forward) and [Elasticsearch](https://docs.fluentbit.io/manual/pipeline/outputs/elasticsearch).

+Each node in the `upstream_servers` group must specify a `name`, `host`, and `port`.
+Additional settings like `tls`, `tls_verify`, and `shared_key` can be configured for
