Hi @shaonbean Could you please shut down all nodes, and re-install x-pack on all nodes? Then please re-start the nodes. It could be that you didn't start up the elected master node before other ones. The elected master node is the one that adds the templates to the cluster, which the rest of the local exporters wait to see before running (default\_local). Thanks, Bohyun ---
