Logstash
Logstash 是开源的服务器端数据处理管道,能够同时从多个来源采集数据,转换数据,然后将数据发送到您最喜欢的存储库中。
Logstash 能够动态地采集、转换和传输数据,不受格式或复杂度的影响。利用 Grok 从非结构化数据中派生出结构,从 IP 地址解码出地理坐标,匿名化或排除敏感字段,并简化整体处理过程。
数据往往以各种各样的形式,或分散或集中地存在于很多系统中。Logstash 支持各种输入选择 ,可以在同一时间从众多常用来源捕捉事件,能够以连续的流式传输方式,轻松地从您的日志、指标、Web 应用、数据存储以及各种 AWS 服务采集数据。

创建运行容器
docker run -it \
--name logstash \
--privileged=true \
-p 5044:5044 \
-p 9600:9600 \
--network wn_docker_net \
--ip 172.18.12.54 \
-v /etc/localtime:/etc/localtime \
-v /usr/local/software/elk/logstash/config:/usr/share/logstash/config \
-v /usr/local/software/elk/logstash/data:/usr/share/logstash/data \
-v /usr/local/software/elk/logstash/logs:/usr/share/logstash/logs \
-v /usr/local/software/elk/logstash/pipeline:/usr/share/logstash/pipeline \
-d logstash:7.17.7
由于挂载有时候不成功,可以先创建容器后把文件拷贝到config, pipeline中。
docker run -it \
--name logstash \
--privileged=true \
-p 5044:5044 \
-p 9600:9600 \
--network wn_docker_net \
--ip 172.18.12.54 \
-v /etc/localtime:/etc/localtime \
-d logstash:7.17.7

kibana创建索引
创建索引对象
在kibana中创建索引,索引名称和logstash.conf中的index名称一致。
#logstash.conf中配置的内容
elasticsearch {
hosts => ["192.168.198.128:9200"] #elasticsearch的ip地址
index => "elk" #索引名称
}
