ELK使用filter收集nginx日志-07

修改nginx日志格式

 log_format  hanye   ‘$proxy_add_x_forwarded_for $remote_user [$time_local] "$request" $http_host‘
    ‘[$body_bytes_sent] $request_body "$http_referer" "$http_user_agent" [$ssl_protocol] [$ssl_cipher]‘
    ‘[$request_time] [$status] [$upstream_status] [$upstream_response_time] [$upstream_addr]‘;
    server {
listen 80;
server_name _;
access_log /data/wwwlogs/access_nginx.log hanye;
    }

安装geoip插件

   [[email protected] elasticsearch]#./bin/elasticsearch-plugin install ingest-geoip
   [[email protected] elasticsearch]# ./bin/elasticsearch-plugin install ingest-user-agent

启动检查logstash和生成nginx日志

[[email protected] config]# ../bin/logstash -f nginx_geoip.yml
  [[email protected] config]# ab -c 20 -n 20 http://192.168.1.252/
