Logstash多行无法正确解析Oracle日志

我一直在使用Logstash管道进行测试，以处理具有以下格式的Oracle多行审核日志：

我的/etc/logstash/conf.d/25-filter.conf：

filter {
    grok {

    grok {

    }
    mutate {

    }
    date {
      locale => "en"
      match => [ "timestamp", "YYYY-MMM-dd HH:mm:ss" ]
    }

    mutate {
      remove_field => [ "timestamp", "year", "day", "monthday", "hour", "min", "sec" ]
    }
}

我的/etc/logstash/conf.d/000-file-in.conf文件：

input {
    file {
        path => [ "/tmp/testora" ]
        start_position => "beginning"
        codec => multiline
        {
                pattern => "^[A-Za-z]{3} [A-Za-z]{3} [0-9]{2} [0-9]{2}:[0-9]{2}:[0-9]{2} [0-9]{4}"
                negate => "true"
                what => "previous"
         }
    }
}

然后我通过运行进行测试：

/usr/share/logstash/bin/logstash -r -f /etc/logstash/conf.d/：

不幸的是，这不是我所期望的。不知何故，它没有对消息进行分块和正确地解析消息。我期待的是类似的东西：

         "ora_audit_action" => "CONNECT",
       "ora_audit_dbuser" => "/",
         "ora_audit_dbid" => "1762369616",

       "ora_audit_clientaddr" => "",
    "ora_audit_actionnum" => "3",
                   "host" => "myhost",
               "@version" => "1",
             "@timestamp" => 2020-10-05T01:16:30.889Z,
                "message" => "Thu Oct  1 23:01:00 2020 +00:00\nLENGTH : '275'\nACTION :[7] 'CONNECT'\nDATABASE USER:[1] '/'\nPRIVILEGE :[6] 'SYSDBA'\nCLIENT USER:[9] 'test_user'\nCLIENT TERMINAL:[5] 'pts/0'\nSTATUS:[1] '0'\nDBID:[10] '1762369616'\nSESSIONID:[10] '4294967295'\nUSERHOST:[21] 'testdevserver'\nCLIENT ADDRESS:[0] ''\nACTION NUMBER:[3] '100'\nThu Oct  1 23:01:00 2020 +00:00\nLENGTH : '296'\nACTION :[29] 'SELECT STATUS FROM V$INSTANCE'\nDATABASE USER:[1] '/'\nPRIVILEGE :[6] 'SYSDBA'\nCLIENT USER:[9] 'test_user'\nCLIENT TERMINAL:[5] 'pts/0'\nSTATUS:[1] '0'\nDBID:[10] '1762369616'\nSESSIONID:[10] '4294967295'\nUSERHOST:[21] 'testdevserver'\nCLIENT ADDRESS:[0] ''\nACTION NUMBER:[1] '3'"

我看到了其中一些信息，但是我也希望它能吐出2条“大块”消息（与模式^[A-Za-z]{3} [A-Za-z]{3} [0-9]{2} [0-9]{2}:[0-9]{2}:[0-9]{2} [0-9]{4}相匹配，作为行的开头，例如Thu Oct 1 23:01:00 2020 +00:00） -相反，它看起来只看到一个？我认为我的模式匹配可能是这里的问题，如果有人可以提供任何提示，谢谢。

此外，我不确定是什么导致了这些错误[1] "_grokparsefailure", [2] "_dateparsefailure"-显然，它无法正确解析内容，但我只是不知道该怎么做。

在与Thu Oct 1 23:01:00 2020 +00:00 匹配的Grok模式下找到

(?<timestamp>%{DAY} %{MONTH}  %{MONTHDAY} %{TIME})

答案 1 :(得分：1)

我认为以下模式应适用于您的多行编解码器并提供所需的分组。

pattern => "^([A-Za-z]{3})(\s*)([A-Za-z]{3})(\s*)([0-9]{1,2})(\s*)([0-9]{2}:[0-9]{2}:[0-9]{2} [0-9]{4})"

此外，在grok过滤器下方，应能为您提供多线的所需细目分类。您可能想根据喜好重命名密钥。


input {
    file {
        path => [ "/tmp/testora" ]
        start_position => "beginning"
        codec => multiline
        {
            pattern => "^([A-Za-z]{3})(\s*)([A-Za-z]{3})(\s*)([0-9]{1,2})(\s*)([0-9]{2}:[0-9]{2}:[0-9]{2} [0-9]{4})"
            negate => "true"
            what => "previous"
         }
    }
}
filter {
    grok {
      match => { "message" => "(?<day>[A-Za-z]{3})%{SPACE}(?<month>[A-Za-z]{3})%{SPACE}(?<monthday>[0-9]{1,2})%{SPACE}(?<hour>[0-9]{1,2}):(?<min>[0-9]{1,2}):(?<sec>[0-9]{2})%{SPACE}(?<year>[0-9]{4})%{SPACE}%{GREEDYDATA:message}" }
      overwrite => [ "message" ]
      add_tag => [ "oracle_audit" ]
    }
    kv {
        field_split => "\n"
        value_split_pattern => "\s*:\s*\[[0-9]*\]\s*"
        source => "message"
    }
    mutate {
      add_field => { "timestamp" => "%{year}-%{month}-%{monthday} %{hour}:%{min}:%{sec}" }
    }
    date {
      locale => "en"
      match => [ "timestamp", "YYYY-MMM-dd HH:mm:ss" ]
    }
    mutate {
      remove_field => [ "timestamp", "year", "day", "monthday", "month", "hour", "min", "sec" ]
    }
}
output {
    stdout {}
}

管道的示例输出如下

{
          "PRIVILEGE" => "SYSDBA",
               "DBID" => "1762369616",
      "ACTION NUMBER" => "100",
           "USERHOST" => "testdevserver",
           "@version" => "1",
               "path" => "/usr/share/logstash/stack/data/file.txt",
          "SESSIONID" => "4294967295",
        "CLIENT USER" => "test_user",
    "CLIENT TERMINAL" => "pts/0",
             "STATUS" => "0",
               "host" => "e8f97b3e53ff",
               "tags" => [
        [0] "multiline",
        [1] "oracle_audit"
    ],
             "ACTION" => "CONNECT",
      "DATABASE USER" => "/",
         "@timestamp" => 2020-10-01T23:01:00.000Z,
            "message" => "+00:00\nLENGTH : '275'\nACTION :[7] 'CONNECT'\nDATABASE USER:[1] '/'\nPRIVILEGE :[6] 'SYSDBA'\nCLIENT USER:[9] 'test_user'\nCLIENT TERMINAL:[5] 'pts/0'\nSTATUS:[1] '0'\nDBID:[10] '1762369616'\nSESSIONID:[10] '4294967295'\nUSERHOST:[21] 'testdevserver'\nCLIENT ADDRESS:[0] ''\nACTION NUMBER:[3] '100'"
}

答案 2 :(得分：0)

根据您的要求，您必须修改希腊模式 在第二个针对LENGH和ACTION参数的grok过滤器中，您正在创建相同的字段 ora_audit_action ，因此它将对数据进行打包并形成一个数组，以便为​​两个参数分别创建字段

grok {
match => { "msg1" => "LENGTH : '(?<ora_audit_length>.*)'.ACTION :\[[0-9]*\] '(?<ora_audit_action>.*)'.*DATABASE USER:\[[0-9]*\] '(?<ora_audit_dbuser>.*)'.*PRIVILEGE :\[[0-9]*\] '(?<ora_audit_priv>.*)'.*CLIENT USER:\[[0-9]*\] '(?<ora_audit_osuser>.*)'.*CLIENT TERMINAL:\[[0-9]*\] '(?<ora_audit_term>.*)'.*STATUS:\[[0-9]*\] '(?<ora_audit_status>.*)'.*DBID:\[[0-9]*\] '(?<ora_audit_dbid>.*)'.*SESSIONID:\[[0-9]*\] '(?<ora_audit_sessionid>.*)'.*USERHOST:\[[0-9]*\] '(?<ora_audit_dbhost>.*)'.*CLIENT ADDRESS:\[[0-9]*\] '(?<ora_audit_clientaddr>.*)'.*ACTION NUMBER:\[[0-9]*\] '(?<ora_audit_actionnum>.*)'" }
}

代替删除字段，您可以使用修剪过滤器将必要的字段列入白名单。

prune {
     whitelist_names => ["ora_audit_action", "ora_audit_dbuser", "ora_audit_dbid", "ora_audit_status", "ora_audit_osuser", "ora_audit_priv", "ora_audit_term", "ora_audit_sessionid", "ora_audit_dbhost", "ora_audit_clientaddr", "ora_audit_actionnum", "host", "@timestamp", "@version", "message"]
}

在代码中，您将隔离时间戳并对其进行重整，但在过滤器部分中，您将其删除，并使用默认的 @timestamp 字段，如果您没有要求，则可以删除不必要的代码。
