添加 requestTimeout 导致 Kibana 启动失败

Question

我正在尝试使用 Elasticsearch-Kibana-Logstash 来处理 Web 日志文件。

有些查询需要一点时间，而 Kibana 很快就会超时，所以我想增加 Kibana 等待 elasticsearch 响应的时间。经过一番搜索，我找到了一些设置 elasticsearch.requestTimeout 的建议。我试图通过将此添加到我的 kibana.yml 文件来增加超时：

elasticsearch.requestTimeout: 5000

这会导致 Kibana 在启动时立即失败并出现以下错误：

这个让我很困惑。我似乎无法在 ElasticSearch 文档中找到对 "payload timeout" 的任何引用。我的网络搜索表明这可能来自 hapijs，但我不确定如何解决这个问题。有人知道吗？

（Kibana、ElasticSearch 和 Logstash 都是 v 6.1.0）

我认为问题在于您将超时值设置得太小，以毫秒为单位，默认值为 30000（请参阅 https://www.elastic.co/guide/en/kibana/6.1/settings.html）：

elasticsearch.requestTimeout:

Default: 30000 Time in milliseconds to wait for responses from the back end or Elasticsearch. This value must be a positive integer.

可能是 elasticsearch.requestTimeout 用于在 hapijs 中设置套接字超时，因为负载超时的默认值似乎是 10 秒（from here）：

route.options.payload.timeout

Default value: to 10000 (10 seconds).

检查负载超时是否小于套接字超时时会失败。但这只是一个假设，我未能在 Kibana 的代码中找到任何证据。
