filebeat 6.1 配置问题

请问新的filebeat 6.1怎么实现日志分类？像下面的配置，使logstash 按分类日志处理，产生不同的index.?
 
###################filebeat config##############
filebeat.prospectors: 
- input_type: log 
paths: - /usr/local/nginx/logs/zixun.oupeng.com.access.log 
document_type: zixun-nginx-access 
 
- input_type: log 
paths: - /usr/local/nginx/logs/water.oupeng.com.access.log 
document_type: water-nginx-access
 
##########logstash config####################
input {
  beats {
    port => 5044
    codec => "json"
  }
}

output {
    if [type] == "zixun-nginx-access" {
    elasticsearch {
        hosts => ["192.168.3.56:9200","192.168.3.49:9200","192.168.3.57:9200"]
        index => "zixun-nginx-access-%{+YYYY.MM.dd}"
        document_type => "%{[@metadata][type]}"
        template_overwrite => true
    }}
    if [type] == "water-nginx-access" {
    elasticsearch {
        hosts => ["192.168.3.56:9200","192.168.3.49:9200","192.168.3.57:9200"]
        index => "water-nginx-access-%{+YYYY.MM.dd}"
        document_type => "%{[@metadata][type]}"
        template_overwrite => true
    }}
