SYSLOG from ATP to Synology

Hello, i am trying to write the logs created by an ATP firewall to a Synology NAS which has the "log center" app installed.

I am able to receive the logs and read it but they are bad-formatted: in brief as you can see from the first image most of the data in inserted in a single field making it difficoult to read

On the zywall i can choose between "syslog" and "CEF/Syslog" (in the example above it was syslog but i tried both)

On the NAS these are the options:

Maybe i have to choose customized format, but I have no clue about how to write the parsing rule.

Thank you to anyone who will reply!
