If "the thing" is generating log files, then it's not using "standard
out". Perhaps you are using that term incorrectly.
On a unix-like system, each process has three standard file descriptors
when it starts: these are standard output (stdout), standard error
(stderr), and standard input (stdin). These three files are inherited
from the parent process, which means that your shell normally sets them
up for the commands that you run. If you do not redirect any of those
three, then they will normally be connected to the controlling terminal
(/dev/tty is the controlling terminal for any process). You can use the
shell's redirection functions to connect those file descriptors to files
rather than to the terminal, or pipe them to another command.
If your application is writing its data to a file without your specific
redirection, then it's not using stdout and you can not pipe it to
another system without writing the data to disk.
