如何使用 logstash 从 csv 输入数据到 elasticsearch？

Question

我正在尝试使用 logstash 将数据插入到 elasticsearch 中，但卡住了。我的配置文件：

logstashCrime.conf
input {
    file {
        path => "C:\elk\sampl.csv"
        start_position => "beginning"
        sincedb_path => "nul"
    }
}

filter {
    csv {
        separator => ","

        columns => ["code","name"]
    }
}

output {
    elasticsearch {
        hosts => ["localhost:9200"]
        index => "crime"
    }
    stdout {
        codec => rubydebug
        }
}

当我尝试使用 logstash-7.2.0\bin\logstash -f c:\elk\logstashCrime.conf:

插入时，我得到了这样的响应

我的 sampl.csv 文件如下所示：

id,name

1,john
2,doe
3,you
4,me

我是 ELK 的新手。任何帮助表示赞赏。另外，我使用 windows 10 作为我的 OS。我使用带有 csv 的 logstash 成功创建了一个索引，但是使用 csv 它没有创建。

我想在Kibana中查看，但是由于没有创建索引，所以在Kibana中看不到索引。

您不能在文件输入的路径选项中使用反斜杠。使用正斜杠。
