input 我们要采集的日志文件路径, 收割机 harvester 监听文件的变化 -->splooer程序 --> 转发 es | logstash | kafka | redis

filebeat.inputs:
- type: stdin #标准输入

output.console: #标准输出

将文件最新发生变化的内容,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"]
收集系统日志
特别分散--> syslog --> file.txt
1.减少无用的数据
2.调整索引名称
3.测试调整模板,设定分片
[root@web01 ~]# cat /etc/filebeat/filebeat.yml
filebeat.inputs:
- type: log
enabled: true
paths:
- /var/log/oldxu.log
include_lines: ['^ERR', '^WARN', 'sshd'] #只看指定的
日志
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 #索引关联的模板名称
setup.template.pattern: system-*
方式一:
###设定system模板的分片数和副本数
#setup.template.settings: #定义索引分片数和副本
# index.number_of_shards: 3
# index.number_of_replicas: 1
方式二:
"number_of_shards": "10",
"number_of_replicas": "1",
1.修改system模板 ---> 添加 shards 分片数数
量,replicas的数量
2.删除模板关联的索引
3.删除filebeat自行指定的分片数和副本数
4.重启filebeat
5.产生新的日志

error日志
1.虚拟主机
[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 bs.oldxu.com.conf
server {
listen 80;
server_name bs.oldxu.com;
2.测试,模拟产生日志
3.配置filebeat
root /code/bs;
access_log /var/log/nginx/bs.oldxu.com.log json;
location / {
index index.html;
}
}
[root@web01 conf.d]# cat bk.oldxu.com.conf
