logstash采集输送日志

建立了个测试java项目spring-boot-log,启动项目

 java -jar spring-boot-log.jar 

此项目会将产生的项目日志存到/home/alen/application/logs/spring-boot-log-info.log

启动

bin/logstash -f hello.conf 

    codec的使用( Coder/decoder 两个单词首字母缩写)
        Codec: 解码编码 数据格式  
        好处 更方便logstash与支持自定义数据格式的运维产品进行使用
    logstash更细化的处理流程
        input->decode->filter->encode->output

hello.conf

input {
 # 从文件读取日志信息 输送到控制台
file {
      path => "/home/alen/application/logs/spring-boot-log-info.log"
	#codec => "json" ## 以JSON格式读取日志
	type => "elasticsearch"
	start_position => "beginning"
	}
}

# filter {
#
# }

output {
	# 标准输出 
	# stdout {}
	# 输出进行格式化,采用Ruby库来解析日志   
	 stdout { codec => rubydebug }
}

访问项目

http://localhost:8070/hello

logstash打印结果

{
          "host" => "localhost.localdomain",
    "@timestamp" => 2018-09-22T13:23:23.946Z,
      "@version" => "1",
       "message" => "2018-09-22 21:23:22.539 [http-nio-8070-exec-5] INFO  com.alen.log.controller.HelloController - 打印日志",
          "path" => "/home/alen/application/logs/spring-boot-log-info.log",
          "type" => "elasticsearch"
}

filter使用
        例子
            切割插件mutate,随意输入一串以|分割的字符,比如 "123|000|ttter|sdfds*=123|dfwe

        配置二 test_filter.conf

input {
 # 从文件读取日志信息 输送到控制台
file {
      path => "/home/alen/application/logs/spring-boot-log-info.log"
	#codec => "json" ## 以JSON格式读取日志
	type => "elasticsearch"
	start_position => "beginning"
	}
}

filter {  
    mutate {  
        split => ["message", "|"]  
    }  
} 

output {
	# 标准输出 
	# stdout {}
	# 输出进行格式化,采用Ruby库来解析日志   
	 stdout { codec => rubydebug }
}

启动

bin/logstash -f test_filter.conf

打印结果message会是根据“|”分割为一个数组

{
          "path" => "/home/alen/application/logs/spring-boot-log-info.log",
       "message" => [
        [0] "2018-09-22 21:45:08.853 [http-nio-8070-exec-2] INFO  com.alen.log.controller.HelloController - 打印日志"
    ],
          "host" => "localhost.localdomain",
      "@version" => "1",
    "@timestamp" => 2018-09-22T13:45:17.204Z,
          "type" => "elasticsearch"
}
