Desperate newbie here! I have set up telegraf on my machine to read an mqtt broker and write to Influxdb Cloud (stripped config below). When I check in the Data Explorer, the bucket can be selected, the tags and fields show up to use as filters, but no matter what button I push or what lever I pull I only get “No Results” in the Data Explorer.
My belief was that if Data Explorer knows about the measurement, tags and fields of some bucket, some data must have been written. Even telegraf in debug mode says “Wrote batch of X metrics” (se below).
I guess there is a real newbie goof here, but I don’t know were go, north/south, up/down or home? Can anyone point me in the right direction to find the elusive data?
