Kibana查询字符串长度 [英] Kibana querying for string length

问题描述

是否可以在Kibana中查询某个长度的值?

Is there a way to query for a value of a certain length in Kibana?

例如，给定以下两个KV对:

For example, given the following two KV pairs:

key: "some"
key: "something"

我想搜索key.length> 5并仅检索某物".

I would like to search for key.length > 5 and retrieve "something" only.

我看到的另一个选项是从Logstash添加标签，但是随后我将不得不重新加载数百GB.

The other option I see is to add a tag from logstash, but then I'll have to reload a couple hundred GB.

推荐答案

您可以在 Kibana 中使用脚本查询来执行此操作. Kibana中的脚本查询，有一个示例对于键长度大于5的脚本查询:

You can use script query to do that in Kibana. Script Query in Kibana, There is an example for script query with key's length more than 5:

{
    "query": {
        "filtered": {
            "filter": {
                "script": {
                    "script": "doc['key'].getValue().length() > 5"
                }
            }
        }
    }
}

此外，您还需要在 elasticsearch 中启用脚本搜索，还需要将以下配置添加到 elasticsearch.yml :

And also you need to enable script search in elasticsearch, you need to add the below config into elasticsearch.yml:

 script.engine.groovy.inline.search: on
