AWS ElasticSearch - Kibana 仪表板未加载

如何解决AWS ElasticSearch - Kibana 仪表板未加载

我配置了一个 AWS ElasticSearch 域。我在 EC2 中安装了 LogStash，它用于将数据推送到 ES 域中，我可以在 Kibana discover 中查看它们。从昨天开始，discover 无法正常加载。当我在主屏幕中单击“发现”时，它会加载一段时间然后停止，但屏幕全是空白。

在 EC2 服务器内部，当我检查 LogStash 状态 (service logstash status) 时，我看到多个错误和警告。

我无法弄清楚它们是否与 Kibana discover 的无响应有关。

解决方法

对我有用的是在 EC2 上本地安装和启动 Kibana。
