在 Logstash 中解析的多种模式答案

【问题标题】：Multiple pattern to parse in Logstash在 Logstash 中解析的多种模式

【问题描述】：

我的日志文件有多个模式，包括 JSON 格式的日志。我想在 grok 插件中解析多个模式，但它似乎不起作用。

'filter {grok {  break_on_match => false 
match =>[ "message", "%{TIMESTAMP_ISO8601:LogDate} %{LOGLEVEL:loglevel} (?<threadName>[^:]+):%{NUMBER:ThreadID} - %{GREEDYDATA:Line}",
           "message","%{TIMESTAMP_ISO8601:LogDate} %{LOGLEVEL:loglevel} (?<threadName>[^:]+):%{NUMBER:ThreadID} - %{IP:Clicnet} - - %{GREEDYDATA:Line}"]}
           json {source => "Line"}mutate{remove_field => [ "Line","ThreadID" ]}}'

即使成功解析 JSON 字符串的行，也有 grokparsefailure 标记。

2017-01-27 11:54:48 INFO PropertiesReader:33 - {"timestamp":1485518878968,"h":"297268184dde", "l":"INFO", "cN":"org .com.logstash.demo", "mN":"loadProperties", "m":"从 /var/tmp/conf 加载属性文件"}

{
       "message" => "2017-01-27 11:54:48 INFO PropertiesReader:33 - {\"timestamp\":1485518878968,\"h\":\"297268184dde\", \"l\":\"INFO\", \"cN\":\"org.com.logstash.demo\", \"mN\":\"loadProperties\", \"m\":\"load property file from /var/tmp/conf\"}",
      "@version" => "1",
    "@timestamp" => "2017-03-20T17:19:16.316Z",
          "type" => "stdin",
          "host" => "ef3b82",
       "LogDate" => "2017-01-27 11:54:48",
      "loglevel" => "INFO",
    "threadName" => "PropertiesReader",
          "tags" => [
        [0] "_grokparsefailure"
    ],
     "timestamp" => 1485518878968,
             "h" => "297268184dde",
             "l" => "INFO",
            "cN" => "org.com.logstash.demo",
            "mN" => "loadProperties",
             "m" => "load property file from /var/tmp/conf"
}

并且没有 JSON 的第二行完全失败

2017-01-20 15:46:16 INFO RequestLog:60 - 10.252.134.34 - - [20/Jan/2017:15:46:16 +0000] "选项 //127.0.0.0:8080 /HTTP/1.1" 404 237 1

    ],

}

【解决方案1】：

花了 5 个小时后，我设法找到了解决方案。使用以下模式成功解析了两个日志行

/opt/logstash/bin/logstash -e 'filter {grok  { match =>{ "message" =>["%{TIMESTAMP_ISO8601:LogDate} %{LOGLEVEL:loglevel} (?<threadName>[^:]+):%{NUMBER:ThreadName} - %{IP:Client} - - %{GREEDYDATA:LogMessage}", "%{TIMESTAMP_ISO8601:LogDate} %{LOGLEVEL:loglevel} (?<threadName>[^:]+):%{NUMBER:ThreadID} - %{GREEDYDATA:Line}"]}}  json {source => "Line"} mutate{remove_field => [ "Line","ThreadID" ]}}'
