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 elasticsearchelasticsearch {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

        <dependency><groupId>net.logstash.logback</groupId><artifactId>logstash-logback-encoder</artifactId><version>7.4</version></dependency>

在logback-spring.xml添加配置

    <appender name="stash" class="net.logstash.logback.appender.LogstashTcpSocketAppender"><destination>127.0.0.1:4560</destination><!-- encoder is required --><encoder class="net.logstash.logback.encoder.LogstashEncoder" /></appender><root level="info"><appender-ref ref="CONSOLE"/><appender-ref ref="stash" /></root>

logstash配置

input {# 从文件读取日志信息tcp {host => "0.0.0.0"mode => "server"port => 4560codec => json_lines}}output {# 输出到 elasticsearchelasticsearch {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: filestreamenabled: truepaths:- /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 elasticsearchelasticsearch {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
