我有一个用于webbapp的java日志文件，该文件是使用SLF4J，Logback和logstash-logback-encoder创建的，用于logstash 1.4.2。虽然各种配置已成功从日志中检索数据，但实际上没有一个配置返回正确的json。根据我读过的每个指南，以下配置应该有效，但不是。

我在Kibana能够获得的最佳回报（如果有任何回报）看起来像这样：
{
"_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
]
}
显然，json转换逻辑运行不正常，所以我缺少什么？
使用this guide配置ELK堆栈。
答案 0 :(得分：0)
这看起来非常可疑：
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不会抱怨它。这应该是它的样子：
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，则可以使用json编解码器为您的伐木工输入。
