it is displaying it as an output on screen and not sure why

# ls -al | grep newone
-rw-r--r--   1 root    root       0 Nov 11 16:08 gnmic-newone

The main purpose of the telegraf config is to write to a file in /tmp/gnmic-newone which it is not doing

Try:

files = [“stdout”, “/tmp/gnmic-newone.out”]

thanks

but still giving the same message with no output
