NGINX日誌格式

log_format main '$remote_addr - $remote_user [$time_local] "$request" '
                    '$status $body_bytes_sent "$http_referer" '
                    '"$http_user_agent" "$http_x_forwarded_for" '
                    '"$request_body" "$upstream_addr" "$uri" "$upstream_response_time" "$upstream_http_name" "$upstream_http_host" "$request_time" 
 
';

安裝filebeat

啟用nginx module

filebeat modules enable nginx

配置NGINX訪問日誌路徑

- module: nginx
  # Access logs
  access:
    enabled: true

    # Set custom paths for the log files. If left empty,
    # Filebeat will choose the paths depending on your OS.
    var.paths: ["/var/log/nginx/*.access.log"]

/etc/filebeat/modules.d/nginx.yml

配置ES地址並修改index名稱

/etc/filebeat/filebeat.yml

#==================== Elasticsearch template setting ==========================

setup.template.settings:
  index.number_of_shards: 1
  #index.codec: best_compression
  #_source.enabled: false
setup.ilm.enabled: false
setup.template.name: "filebeat-nginx"
setup.template.pattern: 
 
"filebeat-nginx-*"

#-------------------------- Elasticsearch output ------------------------------
output.elasticsearch:
  # Array of hosts to connect to.
  hosts: ["192.168.160.34:9200"]
  index: "filebeat-nginx-%{[agent.version]}-%{+yyyy.MM.dd}"

  # Optional protocol and basic auth credentials.
  #protocol: "https"
  username: "elastic"
  password: "pass"

修改日誌的預設匹配規則

/usr/share/filebeat/module/nginx/access/ingest/default.json

新增upstream_addr、upstream_url、upstream_response_time、request_time等欄位

"grok": {
    "field": "message",
    "patterns": [
        "\"?(?:%{IP_LIST:nginx.access.remote_ip_list}|%{DATA:source.address}) - %{DATA:user.name} \\[%{HTTPDATE:nginx.access.time}\\] \"%{DATA:nginx.access.info}\" %{NUMBER:http.response.status_code:long} %{NUMBER:http.response.body.bytes:long} \"%{DATA:http.request.referrer}\" \"%{DATA:user_agent.original}\" \"%{URIHOST:nginx.access.upstream_addr}\" \"%{DATA:nginx.access.upstream_url}\" \"%{NUMBER:nginx.access.upstream_response_time:float}\" \"-\" \"-\" \"%{NUMBER:nginx.access.request_time:float}\""
    ],
    "pattern_definitions": {
        "IP_LIST": "%{IP}(\"?,?\\s*%{IP})*"
    },
    "ignore_missing": true
            }
},

修改fields欄位

/etc/filebeat/fields.yml

新增upstream_addr、upstream_url、upstream_response_time、request_time等欄位

- name: agent
  type: alias
  path: user_agent.original
  migration: true
- name: upstream_response_time
  type: alias
  path: upstream_response_time
  migration: true
- name: upstream_addr
  type: alias
  path: upstream_addr
  migration: true
- name: upstream_url
  type: alias
  path: upstream_url
  migration: true
- name: request_time
  type: alias
  path: request_time
  migration: true

欄位出來以後有黃色小三角,重新整理一下index 的欄位快取就好了
