Syslog forwarding just the Morpheus Application's logs,Exporting%20Logs,-Log%20Settings

The above link describes how to forward the Morpheus Application logs with syslog forwarding.

But Step 1 starts out with “Once you have configured your syslog destination (edit rsyslog.conf)” with no indication of how to do that! I have set it up initially as:
. @
but this gets all logs on the App servers, and I would like just the Morpheus logs…

Can anyone help out on how to do this?
