如何在logstash.conf文件中创建多个索引？

问题描述

我使用以下代码在logstash.conf中创建索引

I used the following piece of code to create an index in logstash.conf

output {
    stdout {codec => rubydebug}
    elasticsearch {
        host => "localhost"
        protocol => "http"
        index => "trial_indexer"
    }
}

要创建另一个索引，我通常将索引名称与上述代码中的另一个。有没有办法在同一个文件中创建许多索引？我是ELK的新人。

To create another index i generally replace the index name with another in the above code. Is there any way of creating many indexes in the same file? I'm new to ELK.

推荐答案

您可以根据您的一个字段的值在索引名称中使用模式。这里我们使用类型字段的值来命名索引：

You can use a pattern in your index name based on the value of one of your fields. Here we use the value of the type field in order to name the index:

output {
    stdout {codec => rubydebug}
    elasticsearch {
        host => "localhost"
        protocol => "http"
        index => "%{type}_indexer"
    }
}

您还可以使用几个 elasticsearch 输出到同一个ES主机或不同的ES主机：

You can also use several elasticsearch outputs either to the same ES host or to different ES hosts:

output {
    stdout {codec => rubydebug}
    elasticsearch {
        host => "localhost"
        protocol => "http"
        index => "trial_indexer"
    }
    elasticsearch {
        host => "localhost"
        protocol => "http"
        index => "movie_indexer"
    }
}

或者也许你要路由你的文件基于一些变量的不同索引：

Or maybe you want to route your documents to different indices based on some variable:

output {
    stdout {codec => rubydebug}
    if [type] == "trial" {
        elasticsearch {
            host => "localhost"
            protocol => "http"
            index => "trial_indexer"
        }
    } else {
        elasticsearch {
            host => "localhost"
            protocol => "http"
            index => "movie_indexer"
        }
    }
}

更新

Logstash 2和5中的语法有所改变：

The syntax has changed a little bit in Logstash 2 and 5:

output {
    stdout {codec => rubydebug}
    if [type] == "trial" {
        elasticsearch {
            hosts => "localhost:9200"
            index => "trial_indexer"
        }
    } else {
        elasticsearch {
            hosts => "localhost:9200"
            index => "movie_indexer"
        }
    }
}
