收到有关InfluxDB问题的查询，这让我抓狂。我一直在通过Telegraf从Windows主机中放入数据，并且工作正常。但是，前几天我的剪切和粘贴记事本显示，当我执行以下操作时，我会获得价值。是同一数据库，我没有删除它或重新创建它。

name:
win_net
key value
--- -----
instance Broadcom NetXtreme Gigabit Ethernet
instance Broadcom NetXtreme Gigabit Ethernet _2
instance Broadcom NetXtreme Gigabit Ethernet _3

但是，今天我这样做了，并且没有返回任何行。

是的，我在正确的数据库中，据我所知，我没有进行任何更改-执行Select *时，那里的数据很多。据我所知，Influx的版本为1.6.1。
此外，我还设计了这种用于查询ScaleIO / VxFlex的架构，对于熟悉的人来说，它看起来是否最佳？群集可以是备份群集也可以是生产群集，备份中有1个池，生产中有4个池。所有的统计信息只是领域。根据我的阅读，这是正确的方法，但是希望对您有帮助。
