我有一个influxDB（称为“ brunosdb”）并使用telegraf，目前有多个活动的输入插件，例如正在跟踪CPU使用率。我可以在grafana中显示。但是，我还有一个活动的MQTT数据入口，用于输入流入线路数据。
当我想在Grafana中绘制MQTT数据时，出现错误
statusText:"Internal Server Error"
data:Object
message:"Metric request error"
isHandled:true
message:"Metric request error"
这是我的查询
from(bucket: "brunosdb/autogen")
|> range(start: -100h)
如果我使用此查询：
from(bucket: "brunosdb/autogen")
|> range(start: -1h)
|> filter(fn: (r) =>
r._measurement == "cpu")
显示的CPU使用率很好。
在InfluxDB本身中，数据的确看起来完全不同：
