filebeat作爲代理安裝在服務器上,監視指定的日誌文件或位置,收集日誌事件,並將他們轉發到logstash,elasticsearch,kafka等

input 我們要採集的日誌文件路徑, 收割機 harvester 監聽文件的變化 -->
splooer程序 --> 轉發 es | logstash | kafka | redis

filebeat.inputs:
 - type: stdin #標準輸入
   enabled: true #啓用
 output.console: #標準輸出
 pretty: true
 enable: true
將文件最新發生變化的內容,存入ES
[root@web01 ~]# cat /etc/filebeat/file.yml
filebeat.inputs:
- type: log
  paths: /var/log/nginx/access.log
  enabled: true
  output.elasticsearch:
  hosts:["10.0.0.161:9200","10.0.0.162:9200","10.0.0.163:9200"]

收集系統日誌

特別分散–> syslog --> file.txt
1.減少無用的數據
2.調整索引名稱
3.測試調整模板,設定分片

[root@web01 filebeat]# cat filebeat_system.yml 
filebeat.inputs:
- type: log
  enabled: true
  paths:
    - /var/log/oldxu.log
  include_lines: ['^ERR','^WARN','sshd'] #只看指定的日誌

output.elasticsearch:
  hosts: ["10.0.0.161:9200","10.0.0.162:9200","10.0.0.163:9200"]
  index: "system-%{[agent.version]}-%{+yyyy.MM.dd}"

setup.ilm.enabled: false
setup.template.name: "system"
setup.template.pattern: "system-*"

setup.template.settings:            #定義索引分片數和副本
  index.number_of_shards: 3
  index.number_of_replicas: 1

1.修改system模板   ---> 添加 shards 分片數數量,replicas的數量
2.刪除模板關聯的索引
3.刪除filebeat自行指定的分片數和副本數
4.重啓filebeat
5.產生新的日誌

收集Nginx日誌

配置filebeat

[root@web01 filebeat]# cat filebeat_nginx.yml 
filebeat.inputs:
- type: log
  enabled: true
  paths:
    - /var/log/nginx/access.log
  json.keys_under_root: true    #默認Flase，還會將json解析的日誌存儲至messages字段
  json.overwrite_keys: true     #覆蓋默認的key，使用自定義json格式的key

output.elasticsearch:
  hosts: ["10.0.0.161:9200","10.0.0.162:9200","10.0.0.163:9200"]
  index: "nginx-%{[agent.version]}-%{+yyyy.MM.dd}"

setup.ilm.enabled: false
setup.template.name: nginx   #索引關聯的模板名稱
setup.template.pattern: nginx-*

收集nginx訪問日誌和錯誤日誌

[root@web01 filebeat]# cat filebeat_access.yml 
filebeat.inputs:
- type: log
  enabled: true
  paths:
    - /var/log/nginx/access.log
  json.keys_under_root: true    #默認Flase，還會將json解析的日誌存儲至messages字段
  json.overwrite_keys: true     #覆蓋默認的key，使用自定義json格式的key
  tags: ["access"]

- type: log
  enabled: true
  paths:
    - /var/log/nginx/error.log
  tags: ["error"]

output.elasticsearch:
  hosts: ["10.0.0.161:9200","10.0.0.162:9200","10.0.0.163:9200"]
  indices:
    - index: "nginx-access-%{[agent.version]}-%{+yyyy.MM.dd}"
      when.contains:
        tags: "access"

    - index: "nginx-error-%{[agent.version]}-%{+yyyy.MM.dd}"
      when.contains:
        tags: "error"

setup.ilm.enabled: false
setup.template.name: nginx   #索引關聯的模板名稱
setup.template.pattern: nginx-*

收集nginx多個虛擬主機的日誌

1.虛擬主機

[root@web01 conf.d]# cat elk.oldxu.com.conf 
server {
    listen 80;
    server_name elk.oldxu.com;
    root /code/elk;
        access_log /var/log/nginx/elk.oldxu.com.log json;

    location / {
        index index.html;
    }
}
[root@web01 conf.d]# cat bk.oldxu.com.conf 
server {
    listen 80;
    server_name bk.oldxu.com;
    root /code/bk;
        access_log /var/log/nginx/bk.oldxu.com.log json;

    location / {
        index index.html;
    }
}
[root@web01 conf.d]# cat bs.oldxu.com.conf 
server {
    listen 80;
    server_name bs.oldxu.com;
    root /code/bs;
        access_log /var/log/nginx/bs.oldxu.com.log json;

    location / {
        index index.html;
    }
}

2.測試,模擬產生日誌

[root@web01 conf.d]# curl -H Host:elk.oldxu.com http://10.0.0.7
elk.oldux.com
[root@web01 conf.d]# curl -H Host:bs.oldxu.com http://10.0.0.7
bs.oldux.com
[root@web01 conf.d]# curl -H Host:bk.oldxu.com http://10.0.0.7
bk.oldux.com

3.配置filebeat
