logstash-output-elasticsearch，为elasticsearch创建索引怎么设置主分片？

template:



{

  "template" : "syslog*",

  "version" : 50001,

  "settings" : {

   "index.refresh_interval" : "5s",

   "index.number_of_replicas" : 0,

   "index.number_of_shards" : 1

  },

...

}



logstash: 



output {

  elasticsearch {

    hosts => ["localhost:9200"]

    index => "syslog%{+YYYY.MM.dd}"

    template => "path_to_your_template.json"

    template_name => "syslog*"

    template_overwrite => true

  }

}

PUT /my_temp_index

{

    "settings": {

        "number_of_shards" :   1,

        "number_of_replicas" : 0

    }

}
