,
"datasource": "Influx-SP",
"definition": "",
"error": null,
"hide": 0,
"includeAll": false,
"label": null,
"multi": false,
"name": "connectivity",
"options": [],
"query": "SHOW TAG VALUES WITH KEY = \"connectivity\" WHERE \"group\" =~ /$group/ AND \"page\" =~ /$page/ AND \"browser\" =~ /$browser/ AND \"category\" =~ /$category/",
"refresh": 1,

现在我想让用户查看特定网址的测量值。目前，group 字段显示所有 URL，用户可以看到所有 url 的列表，无论他是否应该看到它（当然，这是因为查询 SHOW TAG VALUES WITH KEY = \"group\" WHERE \"category\" =~ /$category/ 返回所有条目） .
所以我想获得一些最佳实践来解决这个问题。不幸的是，文档并没有帮助我:-(
【问题讨论】：
【参考方案1】：Grafana 不提供此类功能。 我们实现这种情况的方式是在某些数据源（例如 SQL）中为每个实体配置用户访问权限，然后查询它以显示用户特定的类别/url/等。
此配置可以基于用户的电子邮件/登录名/id 进行，您只能在 Grafana v7.1+ 中将其作为变量“抓取”：
$__user.id 是当前用户的ID $__user.login 是当前用户的登录句柄 $__user.email 是当前用户的电子邮件参考： https://grafana.com/docs/grafana/latest/variables/variable-types/global-variables/#__user
