I want to use grafana to monitor data, utilizing the mathematical abilities of the FLUX query language. For this purpose, I've set up an influxdb and a grafana server, and I installed telegraf.
user@Logger-0271:~$ influx
Connected to http://localhost:8086 version 1.8.2

Within grafana, choosing InfluxDB as Query language (see below) I can plot the measurements just fine. However, if I choose FLUX, I'm only able to plot the measurements in the telegraf database.

I tried to manually insert data into the telegraf database of the InfluxDB, but it does not appear as a grafana measurement.
How can I input data into the InfluxDB and then use FLUX in grafana to perform calculations and plot the data? I've read that the inputs have to be defined in the config file, I don't know how though ...
