Logstash Grok 过滤器读取错误值

Question

我目前正在尝试使用完整的 elk 堆栈（Beats - Logstash - ElasticSearch-Kibana）为我们的应用程序设置一些数据收集。到目前为止一切正常，但我需要捕获应用程序抛出的异常的统计信息（例如 java.lang.IllegalArgumentException）

我对堆栈跟踪本身并不真正感兴趣，所以我继续为异常添加了一个单独的 grok 过滤器。

消息示例：

2016-11-15 05:19:28,801 ERROR [App-Initialisation-Thread] appengine.java:520 Failed to initialize external authenticator myapp Support Access || appuser@vm23-13:/mnt/data/install/assembly app-1.4.12@cad85b224cce11eb5defa126030f21fa867b0dad

grok 语句示例：

grok {
patterns_dir => ["./patterns"]
match => ["message", "%{GREEDYDATA}\n%{JAVAFILE:exception}"]
}

在 grok 调试器上测试显示正确的结果：

{
  "GREEDYDATA": [
    [
      "2016-11-15 05:19:28,801 ERROR [App-Initialisation-Thread] appengine.java:520 Failed to initialize external authenticator myapp Support Access || appuser@vm23-13:/mnt/data/install/assembly app-1.4.12@cad85b224cce11eb5defa126030f21fa867b0dad"
    ]
  ],
  "exception": [
    [
      "java.lang.IllegalArgumentException"
    ]
  ]
}

问题

当我将配置添加到 logstash 时，它会捕获 Caused 字符串而不是异常名称，即使“Caused”字符串位于另一个换行符之后。但是它非常适用于其他异常消息，例如：

016-11-15 06:17:49,691 WARN  [SCReplicationWorkerThread-2] ClientJob.java:207 50345 Error communicating to server `199.181.131.249':`80'. Waiting `10' seconds before retrying... If you see this message rarely, the sc will have recovered gracefully. || appuser@vm55-12:/mnt/deployment/install/app app-3.1.23@cad85b224cce11eb5defa126030f21fa867b0dad

任何建议将不胜感激。

谢谢

您是否在 input 或 filebeat input 中设置了 mutiline ， 像这样显示以 ISO8601 开头的模式
我想也许你 mutiline 没有获取整行

input {
         beats {
            port => 5044
            codec => multiline {
            pattern => "^[0-9]{4}-[0-9]{2}-[0-9]{2} [0-9]{2}:[0-9]{2}:[0-9]{2}[\.,][0-9]{3,7} "
            negate => true
            what => "previous"
            }
           }
        }
