    topic_id => "252nginx-accesslog"
    batch_size => 5
    codec => "json" #写入的时候使用json编码，因为logstash收集后会转换成json格式
      }
      } 
                }

配置logstash从kafka读取日志

     topics => "252nginx-accesslog"

     codec => "json" #写入的时候使用json编码，因为logstash收集后会转换成json格式
     group_id => "252nginx-access-log" 
     consumer_threads => 1
     decorate_events => true 
  }
         kafka {
bootstrap_servers => "192.168.1.252:9092"
topics => "system-log-252"
consumer_threads => 1
decorate_events => true
codec => "json" 
}
}
output {
  if [type] == "252nginx-accesslo" {
  elasticsearch {
    hosts => ["192.168.1.252:9200"]
    index => "252nginx-accesslog-%{+YYYY.MM.dd}"
  }}
