How to change default log files to /var/log/nginx/

Now all our log files go to

Code (Text):

/home/nginx/domains/domainname.com/log/

But I need them to be all together in a singel file in

Code (Text):

/var/log/nginx/

Every time with Lsyncd they get overwritten by the master server on the target servers

EDIT
Found it *--exclude log

---

But still need the in one log file because I scan them even week and send new bot to the bat bod. Now I have to create for every single domain a bash file and a cronjob
