以CAS系列中的使用的Nginx负载均衡器为例

ELK配置

Nginx

修改nginx.conf

  log_format logstash '$http_host $server_addr $remote_addr [$time_local] "$request" '
              '$request_body $status $body_bytes_sent "$http_referer" "$http_user_agent" '
              '$request_time $upstream_response_time';

Elasticsearch

修改elasticsearch.yml

  cluster.name: logstash_elasticsearch
  http.cors.allow-origin: "/.*/"
  http.cors.enabled: true

Logstash

/logstash/conf/logstash_agent.conf

  input {
          file {
                  type => "nginx_access"
                  path => ["/usr/share/nginx/logs/test.access.log"]
          }
  }
  output {
          redis {
                  host => "localhost"
                  data_type => "list"
                  key => "logstash:redis"
          }
  }

/logstash/conf/logstash_indexer.conf

  input {
          redis {
                  host => "localhost"
                  data_type => "list"
                  key => "logstash:redis"
                  type => "redis-input"
          }
  }
  filter {
      grok {
          match => [
              "message", "%{WORD:http_host} %{URIHOST:api_domain} %{IP:inner_ip} %{IP:lvs_ip} \[%{HTTPDATE:timestamp}\] \"%{WORD:http_verb} %{URIPATH:baseurl}(?:\?%{NOTSPACE:request}|) HTTP/%{NUMBER:http_version}\" (?:-|%{NOTSPACE:request}) %{NUMBER:http_status_code} (?:%{NUMBER:bytes_read}|-) %{QS:referrer} %{QS:agent} %{NUMBER:time_duration:float} (?:%{NUMBER:time_backend_response:float}|-)"
          ]
      }
      kv {
          prefix => "request."
          field_split => "&"
          source => "request"
      }
      urldecode {
          all_fields => true
      }
      #date {
      #    type => "log-date"
      #    match => ["timestamp" , "dd/MMM/YYYY:HH:mm:ss Z"]
      #}
      date {
          match => ["logdate" , "dd/MMM/YYYY:HH:mm:ss Z"]
      }
  }
  output {
          elasticsearch {
                  #embedded => false
                  #protocol => "http"
                  hosts => "localhost:9200"
                  index => "access-%{+YYYY.MM.dd}"
          }
  }

注意有些网络示例为旧版本配置，新版本下output的embedded、protocol以及filter的date都有所更新。
