Hi, I have this type of input in nxlog.conf: ``` Module im_udp Host 0.0.0.0 Port 514 Exec parse_syslog(); to_json(); perl_call("process"); ``` My question is, how should I include that JSON output that I get from to_json() to my perl code? Should I write like this?: ``` my ( $event ) = @_; ``` Or it's only the output of parse_syslog_bsd() (as in example for xm_perl https://nxlog.co/documentation/nxlog-user-guide/xm_perl.html)? **More generally, my question is how to include JSON output that i get from to_json() to perl code of xm_perl module?**
