    日志服务：GROK模式参考

    更新时间：Jul 12, 2024

    GROK是一种采用组合多个预定义的正则表达式，用来匹配分割文本并映射到关键字的工具。通常用来对日志数据进行处理。本文档主要介绍GROK的模式说明以及常用语法。

    GROK模式及说明如下表所示。

    说明

    解析类的GROK模式不能使用命名参数形式，即类似SYSLOGBASE、COMMONAPACHELOG、COMBINEDAPACHELOG、HTTPD20_ERRORLOG、HTTPD24_ERRORLOG、HTTPD_ERRORLOG等这些组合解析形式的GROK模式不能使用命名参数形式。
