【Beats】Filebeat收集Nginx日志（十九）

　　本例介绍如何使用Filebeat收集Nginx日志，在【Beats】 Filebeat介绍及使用（十六）中，介绍了如何抓入日志，

　　前面要想实现日志数据的读取以及处理都是自己手动配置的，其实，在Filebeat中，有大量的Module，可以简化我 们的配置，直接就可以使用，如下:

Filebeat Nginx Module使用

　　Nginx日志格式如下：

　　日志格式地址：https://github.com/kubernetes/ingress-nginx/blob/nginx-0.28.0/docs/user-guide/nginx-configuration/log-format.md

1 log_format upstreaminfo
2     '$remote_addr - $remote_user [$time_local] "$request" '
3     '$status $body_bytes_sent "$http_referer" "$http_user_agent" '
4     '$request_length $request_time [$proxy_upstream_name] [$proxy_alternative_upstream_name] $upstream_addr '
5     '$upstream_response_length $upstream_response_time $upstream_status $req_id';

　　1、查看Filebeat支持模块

　　　　命令：./filebeat modules list

　　2、启动Nginx模块

　　　　启动命令：./filebeat modules enable nginx

　　　　禁用命令：./filebeat modules disable nginx

　　　　

　　3、查看modules.d目录中的文件，可以看到nginx.yml配置文件，证明nginx module模块已开启

　　　　命令：ls modules.d/

　　　　

　　4、配置modules.d/nginx.yml文件，指定access.log 和 error.log 的地址

　　　　命令：vim modules.d/nginx.yml

 1 # Module: nginx
 2 # Docs: https://www.elastic.co/guide/en/beats/filebeat/7.6/filebeat-module-nginx.html
 3 
 4 - module: nginx
 5   # Access logs
 6   access:
 7     enabled: true
 8     var.paths: ["/data/logs/nginx-1.16.1/access.log"]
 9 
10     # Set custom paths for the log files. If left empty,
11     # Filebeat will choose the paths depending on your OS.
12     #var.paths:
13 
14   # Error logs
15   error:
16     enabled: true
17     var.paths: ["/data/logs/nginx-1.16.1/error.log"]
18 
19     # Set custom paths for the log files. If left empty,
20     # Filebeat will choose the paths depending on your OS.
21     #var.paths:

 　　5、配置test-nginx.yml文件

 1 # 自定义测试配置文件test-nginx.yml
 2 
 3 # 输入
 4 filebeat.inputs:
 5 
 6 # 指定索引的分区数
 7 setup.template.settings:
 8   index.number_of_shards: 3
 9 
10 filebeat.config.modules:
11   path: ${path.config}/modules.d/*.yml 
12   reload.enabled: false
13 
14 # 输出到指定ES的配置
15 output.elasticsearch:
16   hosts: ["127.0.0.1:9200"]
17   username: "elastic"
18   password: "123456"

 　　6、运行filebeat：

　　　　命令：./filebeat -e -c test-nginx.yml -d "publish"

　　7、查看ES数据如下：

Filebeat 收集JSON格式数据

　　Nginx日志JSON格式如下：

 1 log_format json '{"@timestamp":"$time_iso8601",'
 2              '"host":"$server_addr",'
 3              '"clientip":"$remote_addr",'
 4              '"size":$body_bytes_sent,'
 5              '"responsetime":$request_time,'
 6              '"upstreamtime":"$upstream_response_time",'
 7              '"upstreamhost":"$upstream_addr",'
 8              '"http_host":"$host",'
 9              '"url":"$uri",'
10              '"referer":"$http_referer",'
11              '"agent":"$http_user_agent",'
12              '"status":"$status"}';
13 
14 access_log  /data/logs/nginx-1.16.1/access.log    json;

　　1、配置test-nginx-json.yml文件

 1 # 输入
 2 filebeat.inputs:
 3 - type: log
 4   enabled: true
 5   paths:
 6     - /data/logs/nginx-1.16.1/access.log
 7   # 默认情况下，解码后的JSON放置在输出文档中的“json”键下。
 8   # 如果启用此设置，则将密钥复制到输出文档的顶层。默认值为false。
 9   # 开启后，注意字段类型，要与原顶层字段类型一直
10   json.keys_under_root: false
11 
12   # 如果keys_under_root和启用了此设置，则在发生冲突时，
13   # 来自解码的JSON对象的值将覆盖Filebeat通常添加的字段（类型，源，偏移量等）。
14   json.overwrite_keys: true
15 
16   # 如果启用了此设置，则在JSON解组错误或message_key在配置中定义
17   # 但无法使用时，Filebeat将添加“ error.message”和“ error.type：json”键。
18   json.add_error_key: true
19 
20   # 可选的配置设置，指定要在其上应用行过滤和多行设置的JSON密钥。
21   json.message_key: clientip
22 
23 
24 # 指定索引的分区数
25 setup.template.settings:
26   index.number_of_shards: 3
27 
28 # 输出到指定ES的配置
29 output.elasticsearch:
30   hosts: ["127.0.0.1:9200"]
31   username: "elastic"
32   password: "123456"
