我有一个使用 SLF4J、Logback 和logstash-logback-encoder创建的 webbapp 的 java 日志文件，用于logstash 1.4.2。虽然各种配置已成功从日志中检索数据，但实际上都没有返回正确的 json。根据我阅读的每个指南，以下配置应该可以工作，但不能。

日志样本

/etc/logstash/conf.d/01-lumberjack-input.conf

input {

 lumberjack {
    port => 5000
    type => "logs"
    ssl_certificate => "/etc/pki/tls/certs/logstash-forwarder.crt"
    ssl_key => "/etc/pki/tls/private/logstash-forwarder.key"
  }

}

/etc/logstash/conf.d/10-syslog.conf

filter {
  if [type] == "syslog" {
    grok {
      match => { "message" => "%{SYSLOGTIMESTAMP:syslog_timestamp} %{SYSLOGHOST$
      add_field => [ "received_at", "%{@timestamp}" ]
      add_field => [ "received_from", "%{host}" ]
    }
    syslog_pri { }
    date {
      match => [ "syslog_timestamp", "MMM  d HH:mm:ss", "MMM dd HH:mm:ss" ]
    }
  }

  else if [type] == "json" {

        source => "message"

  }

/etc/logstash/conf.d/30-lumberjack-output.conf

output {
  elasticsearch { host => localhost }
  stdout { codec => rubydebug }
}

/etc/logstash-forwarder（其他机器）

{
  "network": {
    "servers": [ "utility.company.com:5000" ],
    "timeout": 15,
    "ssl ca": "/etc/pki/tls/certs/logstash-forwarder.crt"
  },
  "files": [
    {
      "paths": ["/company/apache-tomcat-8.0.9/logs/vhost1.log"],
      "fields": { "type": "json"  }

    }
   ]
}

我能够在 Kibana 中获得的最佳回报（如果有任何回报）如下所示：

{
  "_index": "logstash-2015.02.04",
  "_type": "json",
  "_id": "8l1rDYTZSceBCklFxAuvAg",
  "_score": null,
  "_source": {
    "message": "{\"@timestamp\":\"2015-02-04T06:03:18.794+00:00\",\"@version\":1,\"message\":\"Attribute Count 1\",\"logger_name\":\"com.company.ws.service.ReportSearchService\",\"thread_name\":\"ajp-nio-8009-exec-1\",\"level\":\"INFO\",\"level_value\":20000,\"HOSTNAME\":\"development.company.com\"}",
    "@version": "1",
    "@timestamp": "2015-02-04T06:13:10.685Z",
    "type": "json",
    "file": "/company/apache-tomcat-8.0.9/logs/vhost1.log",
    "host": "development.company.com",
    "offset": "4907321"
  },
  "sort": [
    1423030390685,
    1423030390685
  ]
}

显然，json转换逻辑不能正常工作，那我错过了什么？

ELK 堆栈是使用本指南配置的。

这看起来很可疑：

else if [type] == "json" {

      source => "message"

}

如果这确实是您的配置文件中的内容，我不明白为什么 Logstash 不抱怨它。这应该是这样的：

else if [type] == "json" {
  json {
    source => "message"
  }
}

或者，如果通过 lumberjack 协议接收的所有消息都是 JSON 消息，您可以使用 json 编解码器作为 lumberjack 输入。
