Question

我正在尝试过滤掉在grok的帮助下收到的日志。以下是样本日志

INFO   | jvm 1    | main    | 2013/04/05 01:08:47.048 | [m[32mINFO  [TaskExecutor-master-2443-ProcessTask [31111111112]] [b2cConfirmationAction] CRON JOB ID : 101AA1C, ACTION : ConfirmationAction , CUSTOMER ID : 000001111111 , EMAIL ADDRESS : abc@gmail.com , SCHEDULE : Every 1 week  , MESSAGE : Execution started for action ConfirmationAction

我在更新logstash conf文件之前使用grok调试器（https://grokdebug.herokuapp.com/）进行测试。以下是我的过滤器代码：

%{LOGLEVEL:level}%{GREEDYDATA:greedydata}%{SPACE}%{YEAR}[/-]%{MONTHNUM}[/-]%{MONTHDAY}%{SPACE}%{HOUR}:%{MINUTE}:%{SECOND}%{GREEDYDATA:gd} \[(?:%{WORD:action})\]%{GREEDYDATA:cronjobresult}

在这里，我正在以

为目标

"level": [ [ "INFO" ] ], "greedydata": [ [ " | jvm 1 | main | 20" ] ], "SPACE": [ [ "", " " ] ], "YEAR": [ [ "13" ] ], "MONTHNUM": [ [ "04" ] ], "MONTHDAY": [ [ "05" ] ], "HOUR": [ [ "01" ] ], "MINUTE": [ [ "08" ] ], "SECOND": [ [ "47.048" ] ], "gd": [ [ " | \u001b[m\u001b[32mINFO [TaskExecutor-master-2443-ProcessTask [31111111112]]" ] ], "action": [ [ "b2cConfirmationAction" ] ], "cronjobresult": [ [ " CRON JOB ID : 101AA4A , ACTION : ConfirmationAction , CUSTOMER ID : 000001111111 , EMAIL ADDRESS : abc@gmail.com , SCHEDULE : Every 1 week , MESSAGE : Execution started for action ConfirmationAction" ] ] }

我的要求是获得cronjobresult下的值，如cron job iD客户ID，具有不同的独立字段，以便我可以在kibana中使用这些值。现在我无法得到它。此外，我已经两次使用greedyData，这个日志的更好的方法将是可观的。

您可以进一步扩展过滤器并明确匹配。例如，要匹配cron作业ID，您可以在过滤器中编写CRON JOB ID : %{BASE16NUM:Cron_job_id}。

如果您不需要日志中的任何数据，那么您只需编写.*而不是GREEDYDATA，它就会被跳过。

以下是日志的完整过滤器，

%{LOGLEVEL:level}%{GREEDYDATA:greedydata}%{SPACE}%{YEAR}[/-]%{MONTHNUM}[/-]%{MONTHDAY}%{SPACE}%{HOUR}:%{MINUTE}:%{SECOND}%{GREEDYDATA:gd} \[(?:%{WORD:action})\] CRON JOB ID : %{BASE16NUM:Cron_job_id},.*CUSTOMER ID : %{NUMBER:Customer_id}.*EMAIL ADDRESS : %{EMAILADDRESS}.*SCHEDULE : %{GREEDYDATA:schedule}.*, MESSAGE : %{GREEDYDATA:Message}

<强>输出：

{
  "level": [
    [
      "INFO"
    ]
  ],
  "greedydata": [
    [
      "   | jvm 1    | main    | 20"
    ]
  ],
  "SPACE": [
    [
      "",
      " "
    ]
  ],
  "YEAR": [
    [
      "13"
    ]
  ],
  "MONTHNUM": [
    [
      "04"
    ]
  ],
  "MONTHDAY": [
    [
      "05"
    ]
  ],
  "HOUR": [
    [
      "01"
    ]
  ],
  "MINUTE": [
    [
      "08"
    ]
  ],
  "SECOND": [
    [
      "47.048"
    ]
  ],
  "gd": [
    [
      " | [m[32mINFO  [TaskExecutor-master-2443-ProcessTask [31111111112]]"
    ]
  ],
  "action": [
    [
      "b2cConfirmationAction"
    ]
  ],
  "Cron_job_id": [
    [
      "101AA1C"
    ]
  ],
  "Customer_id": [
    [
      "000001111111"
    ]
  ],
  "BASE10NUM": [
    [
      "000001111111"
    ]
  ],
  "EMAILADDRESS": [
    [
      "abc@gmail.com"
    ]
  ],
  "local": [
    [
      "abc"
    ]
  ],
  "remote": [
    [
      "gmail.com"
    ]
  ],
  "schedule": [
    [
      "Every 1 week  "
    ]
  ],
  "Message": [
    [
      "Execution started for action"
    ]
  ]
}

请注意，我使用了https://github.com/rgevaert/grok-patterns/blob/master/grok.d/postfix_patterns

中的EMAILADDRESS模式

如果您想在https://grokdebug.herokuapp.com上进行测试，则需要添加

EMAILADDRESSPART [a-zA-Z0-9_.+-=:]+
EMAILADDRESS %{EMAILADDRESSPART:local}@%{EMAILADDRESSPART:remote}

通过检查add custom patterns

作为cusomtom模式

在logstash中使用grok过滤日志
