the format over the wire should be
<priority> date server tag message
if the message does not have this format, rsyslog will add a priority,
date and server to the message
in addition, the date you are setting is not formatted appropriately
the date should be
MMM DD HH:MM:SS
I am not familiar enough with the logger package in python to tell you how
to format it this way.
however, based on the message that you sent earlier, if you set your
format to be
formatter = logging.Formatter("%(name)s %(message)s")
it may be close enough to the correct thing to work.

look in the section on dynafiles. I have not used this feature, so I can't
help directly.
