为什么我们需要两个字段才能让 Kibana 知道监控数据在哪里。

但是当我在这些属性中的任何一个上给我的监控集群时，它都可以工作。我认为elasticsearch.hosts是我的实际生产集群，而不是监控集群。

除了why部分，我对这个集成属性的理解是正确的吗？

有什么想法吗？谢谢

Kibana.yml:

server.host: "ip.ad.re.ss"
#elasticsearch.hosts: ["http://host1:9200","http://host2:9200","FewMoreHosts"]
monitoring.ui.elasticsearch.hosts: ["http://MonitoringNode:9200"]

我没有改变监控节点的elasticsearch.yml中的任何部分。

metricbeat.yml：

output.elasticsearch:
   host: ["http://MonitoringNode:9200"]
setup.kibana:
   host: kibanaHost

在 modules.d / elasticsearch-xpack.yml 中，我保留了默认配置。

elasticsearch.yml:

cer.name: es_cer
node.name: master-1
node.data: false
node.master: true
node.ingest: true
node.max_local_storage_nodes: 3
transport.tcp.port: 9300
bootstrap.memory_lock: false
network.host: 0.0.0.0
http.port: 9200
discovery.seed_hosts: ["master1.ip", "master2.ip","master3.ip"]
cer.initial_master_nodes: ["master-1","master-2"]

监控集群 yml：

network.host: 0.0.0.0
discovery.type: single-node

当我在 Kibana.yml 中启用这两个属性时，我在日志中收到以下错误。

}

但是，如果我只设置 monitoring.ui.elasticsearch.hosts，Kibana 显示数据。
