仅使用一个特定变量授予对仪表板的访问权限

问题描述

我有一个仪表板，其中包含一些变量（在本例中：类别和 URL）：

{
  "templating": {
    "list": [
      {
        "allValue": null,"current": {
          "selected": false,"text": "default","value": "default"
        },"datasource": "Influx-SP","deFinition": "","error": null,"hide": 0,"includeAll": false,"label": null,"multi": false,"name": "category","options": [],"query": "SHOW TAG VALUES WITH KEY = \"category\"","refresh": 1,"regex": "","skipUrlSync": false,"sort": 0,"tagValuesQuery": "","tags": [],"tagsQuery": "","type": "query","useTags": false
      },{
        "allValue": null,"label": "group","name": "group","query": "SHOW TAG VALUES WITH KEY = \"group\" WHERE \"category\" =~ /$category/","text": "_","value": "_"
        },"name": "page","query": "SHOW TAG VALUES WITH KEY = \"page\" WHERE \"group\" =~ /$group/ AND \"category\" =~ /$category/","text": "chrome","value": "chrome"
        },"name": "browser","query": "SHOW TAG VALUES WITH KEY = \"browser\" WHERE \"group\" =~ /$group/ AND \"page\"  =~ /$page/ AND \"category\" =~ /$category/","text": "native","value": "native"
        },"name": "connectivity","query": "SHOW TAG VALUES WITH KEY = \"connectivity\" WHERE \"group\" =~ /$group/ AND \"page\"  =~ /$page/ AND \"browser\" =~ /$browser/ AND \"category\" =~ /$category/","useTags": false
      }
    ]
  }
}

现在我想允许用户查看特定网址的测量值。目前，字段 group 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，文档没有帮助我:-(

解决方法

Grafana 不提供此类功能。 我们实现这种情况的方法是在某些数据源（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。

可以根据用户的电子邮件/登录名/ID 进行此配置，您只能在 Grafana v7.1+ 中将其“抓取”为变量：

• ${__user.id} 是当前用户的 ID
• ${__user.login} 是当前用户的登录句柄
• ${__user.email} 是当前用户的邮箱
