本文介绍如何动态构建新字段,将现有日志包装成一个整体,添加到新构建的字段中。
示例:您可以使用如下加工语法复制字段content为k1_content_copy、字段name为k2_name_copy、字段School为k3_school_copy,并将加工后的日志包装成一个整体。然后再构建一个新字段__extract_others__,将日志添加到该字段中,并丢弃字段k1_content_copy和k3_school_copy。

加工规则
e_set("k1_content_copy", v("content"), "k2_name_copy", v("name"), "k3_school_copy", v("School"))
e_set("__extract_others__", dct_delete(KEEP,"k1_content_copy","k3_school_copy"))
