Hello
I am using telegraf to retrieve the data with the following subscription_mode = “on_change”
Thereby I can have no data for several hours.
I am using the following flux request and I would like to use : fill(usePrevious: true) because I feel that it will use the latest value.
Any help will be welcome
from(bucket: “interfaces”)

|> filter(fn: (r) => r[“device”] == “192.168.59.150”)
|> filter(fn: (r) => r[“name”] == “Management1”)
