06 . ELK Stack + kafka集群
简介
Filebeat用于收集本地文件的日志数据。 它作为服务器上的代理安装，Filebeat监视日志目录或特定的日志文件，尾部文件，并将它们转发到Elasticsearch或Logstash进行索引。
logstash 和filebeat都具有日志收集功能，filebeat更轻量，使用go语言编写，占用资源更少，可以有很高的并发，但logstash 具有filter功能，能过滤分析日志。一般结构都是filebeat采集日志，然后发送到消息队列，如redis，kafka。然后logstash去获取，利用filter功能过滤分析，然后存储到elasticsearch中。Kafka是LinkedIn开源的分布式发布-订阅消息系统，目前归属于Apache定级项目。Kafka主要特点是基于Pull的模式来处理消息消费，追求高吞吐量，一开始的目的就是用于日志收集和传输。0.8版本开始支持复制，不支持事务，对消息的重复、丢失、错误没有严格要求，适合产生大量数据的互联网服务的数据收集业务。

ELK集群部署请看上一篇博客
https://www.cnblogs.com/you-men/p/13361910.html
配置使用zookeeper和kafka请看我写的另一篇博客
https://www.cnblogs.com/you-men/p/12884779.html
使用Logstash和Kafka交互
编辑logstash配置文件
input{
stdin{}
}
output{
kafka{
topic_id =>"kafkatest"
bootstrap_servers => "192.168.43.47:9092"
batch_size => 5
}
stdout{
codec => "rubydebug"
}
}
启动logstash,输入数据
./bin/logstash -f kafka.conf
zhoujian
{
"@timestamp" => 2020-07-24T07:11:26.235Z,
"message" => "zhoujian",
"host" => "logstash-30",
"@version" => "1"
}
youmen
{
"@timestamp" => 2020-07-24T07:11:29.441Z,
"message" => "youmen",
"host" => "logstash-30",

}
kafka中查看写入数据
# 查看kafka现有的topic
./bin/kafka-topics.sh --list --bootstrap-server 192.168.43.47:9092,192.168.43.151:9092,192.168.43.43:9092
kafkatest
test-you-io
# 查看kafkatest里面消息
./bin/kafka-console-consumer.sh --bootstrap-server 192.168.43.47:9092,192.168.43.151:9092,192.168.43.43:9092 --topic kafkatest --from-beginning

数据写入成功,kafka配置完成
配置Filebeat
输出日志到kafka
