logstash收集Nginx日志，轉換為JSON格式

Nginx日志處理為JSON格式，並放置在http區塊：

 log_format  json  '{"@timestamp":"$time_iso8601",'
                      '"@version":"1",'
                      '"client":"$remote_addr",'
                      '"url":"$uri",'
                      '"status":"$status",'
                      '"domain":"$host",'
                      '"host":"$server_addr",'
                      '"size":"$body_bytes_sent",'
                      '"responsentime":"$request_time",'
                      '"referer":"$http_referer",'
                      '"useragent":"$http_user_agent"'
                       '}';
access_log  logs/access_json.log  json;

 

logstash配置文件：

input {
       file {
      path =>"/usr/local/nginx/logs/access_json.log"
      codec =>"json"
      start_position => "beginning"

        }
}

filter{
   json {
                source => "message"
                skip_on_invalid_json => true
                }
}
output{


      elasticsearch {
       hosts =>["172.16.3.160:9200"]
       index => "logstash-zabbix-nginx-log-%{+YYYY.MM.dd}"

           }
}
