Filebeat Nginx Module 自定义字段

Filebeat Nginx Module 自定义字段

一、修改/usr/local/nginx/conf/nginx.conf中

log_format access '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for" '
                      '"$http_x_real_ip" "$server_addr" "$host" '
                      '$request_time $upstream_response_time "$upstream_addr" '
                      '"$time_iso8601"';
    access_log  /var/log/nginx/access.log  access;

二、启用filebeat的nginx module

filebeat modules enable nginx

三、filebeat nginx module 增加字段

文件 /usr/share/filebeat/module/nginx/access/ingest/default.json 中
原始：

 "grok": {
      "field": "message",
      "patterns":[
        "\"?%{IP_LIST:nginx.access.remote_ip_list} - %{DATA:nginx.access.user_name} \\[%{HTTPDATE:nginx.access.time}\\] \"%{GREEDYDATA:nginx.access.info}\" %{NUMBER:nginx.access.response_code} %{NUMBER:nginx.access.body_sent.bytes} \"%{DATA:nginx.access.referrer}\" \"%{DATA:nginx.access.agent}\""
        ],
      "pattern_definitions": {
        "IP_LIST": "%{IP}(\"?,?\\s*%{IP})*"
      }

修改后：

"grok": {
      "field": "message",
      "patterns":[
        "\"?%{IP_LIST:nginx.access.remote_ip_list} - %{DATA:nginx.access.user_name} \\[%{HTTPDATE:nginx.access.time}\\] \"%{GREEDYDATA:nginx.access.info}\" %{NUMBER:nginx.access.response_code} %{NUMBER:nginx.access.body_sent.bytes} \"%{DATA:nginx.access.referrer}\" \"%{DATA:nginx.access.agent}\" \"%{DATA:nginx.access.xff}\" \"%{DATA:nginx.access.x_real_ip}\" \"%{DATA:nginx.access.server_addr}\" \"%{DATA:nginx.access.host}\" %{DATA:nginx.access.request_time} %{DATA:nginx.access.upstream_response_time} \"%{DATA:nginx.access.upstream_addr}\" \"%{DATA:nginx.access.time_iso8601}\""
        ],
      "pattern_definitions": {
        "IP_LIST": "%{IP}(\"?,?\\s*%{IP})*"
      }

四、文件 /etc/filebeat/fields.yml 中

找到nginx字段配置

在

      - name: agent
              type: text
              description: >
                Contains the un-parsed user agent string. Only present if the user
                agent Elasticsearch plugin is not available or not used.

后面加入

- name: xff
              type: group
              description: >
                http_x_forwarded_for.
            - name: x_real_ip
              type: group
              description: >
                http_x_real_ip.
            - name: server_addr
              type: group
              description: >
                server_addr 服务器地址.
            - name: host
              type: group
              description: >
                host http_host http主机头.
            - name: request_time
              type: group
              description: >
                request_time 请求时间.
            - name: upstream_response_time
              type: group
              description: >
                upstream_response_time 后端响应时间.
            - name: upstream_addr
              type: group
              description: >
                upstream_addr 后端地址.
            - name: time_iso8601
              type: group
              description: >
                time_iso8601 iso8601格式时间.

五、Filebeta中 nginx 日志路径定义

在文件 /etc/filebeat/modules.d/nginx.yml 中修改日志路径

- 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: ["/data/wwwlogs/*.log*"]

  # Error logs
  error:
    enabled: true

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