+# Remote cluster information
+Introduced 1.0
+{: .label .label-purple }
+
+This operation provides connection information for any remote OpenSearch clusters that you've configured for the local cluster, such as the remote cluster alias, connection mode (`sniff` or `proxy`), IP addresses for seed nodes, and timeout settings.
+
+The response is more comprehensive and useful than a call to `_cluster/settings`, which only includes the cluster alias and seed nodes.
