嗨，我得到以下错误：

"tags" => [
    [0] "beats_input_codec_plain_applied",
    [1] "_grokparsefailure"
]

我的logstash-sample.conf如下

input {
beats {
    port => "5044"
}
}

filter {
    grok {
         match => ["message","HTTPD20_ERRORLOG \[%{HTTPDERROR_DATE:timestamp}\] \[%{LOGLEVEL:loglevel}\] (?:\[client %{IPORHOST:clientip}\] )$
    }
}

output {
    stdout { codec => rubydebug }
}

有人能帮我一下吗？我在这里干什么？也在模式中{loglevel:loglevel}]（？：[客户%{iporhost:clientip}我需要指定loglevel和clientip吗？
我的日志示例：

首先，我建议大家学习一下grok的一些基本知识以及它是如何工作的。在答案末尾添加一些有用的资源。
日志中的当前模式类似于timestamp classname loglevel logmessage
对于下面问题中的日志示例，它是一个示例管道，但不确定是否需要多行来捕获堆栈跟踪。在这种情况下，可以扩展以下内容。

filter {
   grok{
     match =>  { "message" => "%{TIMESTAMP_ISO8601:timeStamp}%{SPACE}\[%{DATA:className}\]%{SPACE}%{LOGLEVEL:logLevel}%{SPACE}%{GREEDYDATA:message}"} 
     overwrite => [ "message" ]
   }
   date {
      match => ["timeStamp","yyyy-MM-dd HH:mm:ss,SSS"]
      timezone => "Europe/London"
      target => "@timestamp"
      remove_field => ["timeStamp"]
    }

}

输出事件如下所示

{
      "logLevel" => "INFO",
      "@version" => "1",
          "path" => "/usr/share/logstash/stack/data/data.log",
     "className" => "Classname",
          "host" => "95b3783b146a",
    "@timestamp" => 2020-10-09T13:24:35.004Z,
       "message" => "LOGG- Sending message : Test"
}
{
      "logLevel" => "ERROR",
      "@version" => "1",
          "path" => "/usr/share/logstash/stack/data/data.log",
     "className" => "Classname",
          "host" => "95b3783b146a",
    "@timestamp" => 2020-10-09T13:24:35.004Z,
       "message" => "InternetApp- in details."
}
