ELK框架Logstash配合Filebeats和kafka使用

ELK框架Logstash配合Filebeats和kafka使用

配置文件结构

配置文件为：logstash.yml

需要自己新建conf文件，设置input，filter和output，文件结构如下，自带的logstash-sample.conf内容如下

input { 

}
filter {

}
output {

}

启动命令

bin/logstash -f config/logstash.conf

https://www.elastic.co/guide/en/logstash/current/input-plugins.html

input为标准输入，output为标准输出

input { 
  stdin { } 
}
output {
  elasticsearch { 
    hosts => ["localhost:9200"] 
  }
  stdout { }
}

input为log文件

output为标准输出

input {
  # 从文件读取日志信息
  file {
    path => "/xxx/demolog/logs/myapp-info.log"
    type => "ghn"
    start_position => "beginning"
  }

}

output {
  stdout { codec => rubydebug }
}

output为es

input {
  # 从文件读取日志信息
  file {
    path => "/xxx/demolog/log/demolog-*.log"
    type => "ghn"
    start_position => "beginning"
  }

}

output {
  # 输出到 elasticsearch
  elasticsearch {
    hosts => ["localhost:9200"] 
    user => "elastic"
    password => "xxxxxx"
    ssl => "true"
    cacert => "/xxx/elk/logstash-8.9.1/config/certs/http_ca.crt"
    index => "ghn-%{+YYYY.MM.dd}"
  }
  stdout {  }
}

input为tcp

配合springboot/springcloud使用

springboot配置

官方github：https://github.com/logfellow/logstash-logback-encoder
在pom.xml添加依赖

        
            net.logstash.logback
            logstash-logback-encoder
            7.4
        

在logback-spring.xml添加配置

    
        127.0.0.1:4560
        
        
    

    
        
        
    

logstash配置

input {
  # 从文件读取日志信息
  tcp {
    host => "0.0.0.0"
    mode => "server"
    port => 4560
    codec => json_lines
  }

}

output {
  # 输出到 elasticsearch
  elasticsearch {
    hosts => ["localhost:9200"] 
    user => "elastic"
    password => "xxxxxx"
    ssl => "true"
    cacert => "xxx/logstash-8.9.1/config/certs/http_ca.crt"
    index => "ghn-%{+YYYY.MM.dd}"
  }
  stdout { }
  # stdout { codec => rubydebug }
}

• logstash终端查看
  

• kibana查看
  

input为filebeats

filebeats配置

• 配置文件位置：filebeat-8.9.1-darwin-aarch64/filebeat.yml，修改如下部分，指定log位置为springboot的目录

filebeat.inputs:
- type: filestream
  enabled: true
  paths:
    - /xxx/xxx/*.log

• 启动

./filebeat -e -c filebeat.yml -d "publish"

与logstash建立了连接，启动成功

logstash配置

input {
  beats {
    port => 5044
  }
}

output {
  elasticsearch {
    hosts => ["localhost:9200"] 
    user => "elastic"
    password => "xxxxxx"
    ssl => "true"
    cacert => "/xxxx/logstash-8.9.1/config/certs/http_ca.crt"
    index => "%{[@metadata][beat]}-%{[@metadata][version]}-%{+YYYY.MM.dd}"
  }
}

• 启动logstash

bin/logstash -f config/logstash-filebeat.conf

• 获取从filebeats发来的日志
  

kibana

• kibana中数据视图已经能够看到
  

• 查看详情
  

input为kafka

官方文档：https://www.elastic.co/guide/en/logstash/current/use-filebeat-modules-kafka.html

filebeats设置

output.kafka:
  hosts: ["localhost:9092"]
  topic: "filebeat"
  codec.json:
    pretty: false

./filebeat -e -c filebeat.yml -d "publish"

logstash配置

input {
  kafka {
    bootstrap_servers => ["localhost:9092"]
    topics => ["filebeat"]
    codec => json
  }

}

output {
  # 输出到 elasticsearch
  elasticsearch {
    hosts => ["localhost:9200"] 
    user => "elastic"
    password => "xxxxxx"
    ssl => "true"
    cacert => "/xxx/elk/logstash-8.9.1/config/certs/http_ca.crt"
    index => "ghn-%{+YYYY.MM.dd}"
  }
  stdout { }
  # stdout { codec => rubydebug }
}

• kafka启动
  

• logstash查看
  

• kafka关闭
