[Question] <title>Pay attention to the value and other fields when importing and monitoring through ymal files in batches: spaces need to be added later, and UTF8 is required when the character set is required

### Question

通过批量导入ymal文件发现报错
一个是ymal文件保存的时候字符集需要是utf8，还有一个问题要注意填写的字段的冒号后面需要有一个空格，注意这两点一般导入就没啥问题了。或者使用excel来导入。

No file or test is named in the issue. Start by locating the documentation or importer guidance for batch YAML monitoring imports; update the relevant guidance to cover UTF-8 encoding and spaces after colons, and consider the Excel import alternative. Done means a newcomer can follow the documented requirements without encountering this error.
