Logstash-将字符串转换为整数 [英] Logstash - Converting String to an Integer

问题描述

在我的Logstash中，我具有以下配置:

In my Logstash I have below configuration:

filter {
   mutate {
        add_field => {
            "doclength" => "%{size}"
        }
        convert => {"doclength" => "integer"}
        remove_field => ["size"]
    }
}

我打算将字段" doclength "作为整数存储到ElasticSearch中.但是以某种方式在ES中，它仅将映射显示为"字符串".

I intend to store the field "doclength" into ElasticSearch as an integer. But somehow in ES, it shows mapping as "string" only.

不确定我在这里缺少什么，预期的行为与实际行为不符.

Not sure what I am missing in here, the expected behavior is not matching up with the actual one.

推荐答案

尝试一下，它可以在我的机器上工作.

Try this one, it worked on my machine.

filter {
   mutate {
        convert => {"size" => "integer"}
        rename => { "size" => "doclength" }
    }
}
