Question

我正在使用tomcat安装logstash并且有抓住java堆栈跟踪调用的问题，以下是我的配置

input   {
 udp {
   type => "tomcat"
   port => "514"
   format => "plain"

 }

}

filter{
multiline {
            pattern => "(^.+Exception.*)|(^\s+at .+)|(^\s+... \d+ more)|(^\s*Caused by:.+)"
            what => "previous"
}
}

以下是tomcat的示例日志

我累了所有的组合，没有工作:(我不知道它对其他人有用..

编辑：

我已经尝试过以及它也不起作用

pattern => "^%{TIMESTAMP_ISO8601}"
       negate => true

以下是结果

更新：

我使用udp协议在调试模式下运行logstash，<139>中出现了一些奇怪的数字@messages，请参阅以下调试输出，如果我使用nc命令发送样本日志它可以工作但是以某种方式与tomcat syslog无法正常工作

       "message" => "<139>2014-03-28 13:52:25,548 [] [] [thread-pool2] ERROR org.apache.catalina.core.ContainerBase.[engine].[localhost] - Exception Processing ErrorPage[errorCode=500, location=/error/error500.jsp]\n",

是否所有日志都以日期时间开头？

您可以将其用作模式。例如，

input {
    stdin {
    }
}

filter {
    multiline {
       pattern => "^%{TIMESTAMP_ISO8601} "
       negate => true
       what => previous
    }
}

output {
    stdout {debug => true}
}

此过滤器在我的日志上工作。希望它可以帮助你:)）

用java日志记录多线问题
