Spring boot 用于部署到Cloud Foundry的Spring引导的Logstash管道模板

我正在寻找一个非常基本的管道模板，它允许我正确地索引日志消息的所有可用字段

我使用SpringBoot（2.1.x）开箱即用，将其部署到CloudFoundry，并通过stdout/logdrain记录到Logstash，最终记录到Elasticsearch

我已经搜索了互联网，只找到了一个云铸造应用程序模板：

input {
  http {
    port => "5044"
    user => "inputuser"
    password => "inputpassword"
  }
}

filter {
 grok {
    #patterns_dir => "{{ .Env.HOME }}/grok-patterns"
    match => { "message" => "%{SYSLOG5424PRI}%{NONNEGINT:syslog5424_ver} +(?:%{TIMESTAMP_ISO8601:syslog5424_ts}|-) +(?:%{HOSTNAME:syslog5424_host}|-) +(?:%{NOTSPACE:syslog5424_app}|-) +(?:%{NOTSPACE:syslog5424_proc}|-) +(?:%{WORD:syslog5424_msgid}|-) +(?:%{SYSLOG5424SD:syslog5424_sd}|-|)%{SPACE}%{GREEDYDATA:message}" }
    add_tag => [ "CF","CF-%{syslog5424_proc}","_grokked"]
    add_field => { "format" => "cf" }
    tag_on_failure => [ ]
    overwrite => [ "message" ]
  }
  if [syslog5424_proc] =~ /(A[pP]{2}.+)/ {
    mutate { add_tag => ["CF-APP"] }
    mutate { remove_tag => ["_grokked"] }
  }
  if  ("CF-APP" in [tags]) or !("CF" in [tags])  {
    if [message] =~ /^{.*}/ {
      json {
        source => "message"
        add_tag => [ "json", "_grokked"]
      }
    }
  }
  if !("_grokked" in [tags]) {
    mutate{
      add_tag => [ "_ungrokked" ]
    }
  }
}

output {
    #stdout { codec => rubydebug }
    if ("_grokked" in [tags]) {
      elasticsearch {
        hosts => ["https://ac9537fc444c489bb63ac44064c54519.elasticsearch.lyra-836.appcloud.swisscom.com"]
        user => "myuser"
        password => "mypassword"
        ssl => true
        ssl_certificate_verification => true
        codec => "plain"
        workers => 1
        index => "parsed-%{+YYYY.MM.dd}"
        manage_template => true
        template_name => "logstash"
        template_overwrite => true
      }
    } else {
      elasticsearch {
        hosts => ["https://ac9537fc848c489bb63ac44064c54519.elasticsearch.lyra-836.appcloud.swisscom.com"]
        user => "myuser"
        password => "mypassword"
        ssl => true
        ssl_certificate_verification => true
        codec => "plain"
        workers => 1
        index => "unparsed-%{+YYYY.MM.dd}"
        manage_template => true
        template_name => "logstash"
        template_overwrite => true
      }
   }
}

这看起来已经相当冗长，只涵盖CloudFoundry字段，但忽略了所有特定于应用程序的字段，如日志级别（它不遵循键/值符号，而是日志消息中的固定位置）

一个示例日志消息是：

2019-10-03T09:20:09.37+0200 [APP/PROC/WEB/0] OUT 2019-10-03 09:20:09.378  INFO 19 --- [           main] o.s.b.a.e.web.EndpointLinksResolver      : Exposing 2 endpoint(s) beneath base path '/actuator'

非常感谢您的帮助，非常感谢

更新：根据第一条评论，我将Spring Boot应用程序配置为将消息记录为json。在CloudFoundry中，我使用配置为logdrain的用户提供的服务将这些日志发送到Logstash。Logstash收到如下消息：

<14>1 2019-10-03T17:29:17.547195+00:00 cf-organization.cf-space.cf-app abc9dac6-1234-4b62-9eb4-98d1234d9ace [APP/PROC/WEB/1] - - {"app":"cf-app","ts":"2019-10-03T17:29:17.546+00:00","logger":"org.springframework.boot.web.embedded.netty.NettyWebServer","level":"INFO","class":"org.springframework.boot.web.embedded.netty.NettyWebServer","method":"start","file":"NettyWebServer.java","line":76,"thread":"main","msg":"Netty started on port(s): 8080"}

我需要如何调整grok/output以将key

message

的值作为json发送到Elasticsearch

好的，所以我通过以下步骤成功地做到了这一点，多亏了：

Spring启动应用程序 添加此依赖项 添加以下src/main/resources/logback-spring.xml

谢谢@Strelok为我指明了正确的方向

为什么不使用登录日志存储JSON格式？我想你根本不需要解析它。谢谢你，@Strelok。我将我的应用程序重新配置为以json登录。非常不幸的是，平台在json前面添加了一些文本，因此Logstash不能简单地将json转发给Elasticsearch。我想我已经接近解决方案了，也许你有另一个提示，现在如何配置Logstash来删除前面的文本？
