一、logstash安装

logstash作为kafka日志的消费者

1、将文件上传到服务器/home/tools路径下

tar -zxvf logstash-7.4.2.tar.gz   -C /usr/local/

 

进入/usr/local/logstash-7.4.2，查看文件

2、创建script文件夹

文件文件logstash-script.conf

## multiline 插件也可以用于其他类似的堆栈式信息，比如linux的内核日志
input {
   ## 订阅kafka的所有app-log-开头和error-log-开头的主题
    kafka {
      ## app-log-服务名称
      topics_pattern => "app-log-.*"
      bootstrap_servers => "47.xx.xx.120:9092"
      codec => json
      consumer_threads => 1  ##增加consumer的并行消费线程数
      decorate_events => true
      # auto_offset_rest => "latest"
      group_id => "app-log-group"
    }
     kafka {
          ## error-log-服务名称
          topics_pattern => "error-log-.*"
          bootstrap_servers => "47.xx.xx.120:9092"
          codec => json
          consumer_threads => 1
          decorate_events => true
          # auto_offset_rest => "latest"
          group_id => "error-log-group"

        }
}
## 收到数据后，对数据进行过滤
filter {
  ## 时区转换
  ruby {
    code => "event.set(‘index_time‘,event.timestamp.time.localtime.strftime(‘%Y.%m.%d‘))"
  }

  if "app-log" in [fields][logtopic]{
    grok {
      ## [表达式]
      match => ["message","\[%NOTSPACE:currentDateTime}\] \[%{NOTSPACE:level}\] \[%NOTSPACE:thread-id}\] \[%NOTSPACE:class}\] \[%NOTSPACE:hostName}\] \[%NOTSPACE:ip}\] \[%NOTSPACE:applicationName}\] \[%NOTSPACE:location}\] \[%NOTSPACE:messageInfo}\] ## (\‘\‘|%{QUOTEDSTRING:throwable})"]
    }
  }

  if "error-log" in [fields][logtopic]{
    grok {
      ## [表达式]
      match => ["message","\[%NOTSPACE:currentDateTime}\] \[%{NOTSPACE:level}\] \[%NOTSPACE:thread-id}\] \[%NOTSPACE:class}\] \[%NOTSPACE:hostName}\] \[%NOTSPACE:ip}\] \[%NOTSPACE:applicationName}\] \[%NOTSPACE:location}\] \[%NOTSPACE:messageInfo}\] ## (\‘\‘|%{QUOTEDSTRING:throwable})"]
    }
  }
}

## 输出到控制台
output {
    stdout { codec => rubydebug }
}

　　

 

3、logstash配置文件

技术分享图片

1) logstash配置文件: /config/logstash.yml

2) JVM 参数文件： /config/jvm.options   logstash是很吃内存的，如果是8G的内存，可以配置为6G。我这里是测试使用，配置256M

-Xms256m
-Xmx256m

如果使用了对外内存，建议配置60%，如果是8G，配置为4G

 3) 日志格式配置文件： log4j2.properties

4)  制作Linux服务参数： /config/setartup.options

5)  pipelines.yml

增加workers工作线程数  可以有效的提升logstash性能

pipeline.workers: 16

 

启动 logsstash

 /usr/local/logstash-7.4.2/bin/logstash -f /usr/local/logstash-7.4.2/script/logstash-script.conf  &
