Question

我目前正在尝试使用完整的elk堆栈（Beats - Logstash - ElasticSearch-Kibana）为我们的应用设置一些数据集合。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感兴趣所以我继续前进并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调试器上进行测试会显示正确的结果：

{
  "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”字符串在另一个新行字符之后。但是它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

任何建议都将受到赞赏。

您是否在输入或文件输入中设置了多行，像这样显示模式从ISO8601开始我想也许你多说不取整行

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"
            }
           }
        }
