InfluxDB / Grafana - Spreadingfactor

Hello at all

i have a question to the influxDB Part of Chirpstack Integration.
as the documentation says, informations like SF are stored as DR in de device_uplink meassurement. i want to draw e graph in Grafana, which shows the history of SF/DR.

As the DR filed is a tag, i have problems with the influxDB querry - does anyone knows, how to do such a select? InfluxDB says, you can’t use selects on tags only - so you need a field (for example value).

So if anyone could tell me, how to do the influx querry, i would be very happy.

thanks in advance,
sil

for example: select dr,snr,rssi from device_uplink
but you need to know the your actual measurement names and tags
anyway refer to https://docs.influxdata.com/influxdb/v1.7/query_language/data_exploration/
in grafana you need to specify right tags and field names while creating dashboard panels.

hey, thx
thats a solution i can use. i was hoping to have it without field - but i can set the filed value to hidden in grafana.

regards, sil
