Hello, is there a way to process more than the $MSG macro with a syslog-ng parse filter? We are forwarding our syslogs via rsyslog in this format (client config): $template tmpl_forward,"%hostname% %syslogtag% \"%msg%\"\n" *.* @@syslog:514;tmpl_forward I have created the following parser rule in syslog-ng: parser p_INTERNAL { csv-parser(columns("INTERNAL.TIME_LOGGED", "INTERNAL.TIME_RECEIVED", "INTERNAL.RELAY_HOST", "INTERNAL.LOGGING_HOST", "INTERNAL.PROGRAM", "INTERNAL.MESSAGE") flags(escape-double-char,strip-whitespace) delimiters(" ") quote-pairs('""[]') ); }; I want to create the logfile in this format: destination d_intern2 { file("/log-local/__OPS__/$YEAR-$MONTH/xxx-${INTERN.LOGGING_HOST}.log" ); }; Unfortunately, syslog-ng does not fill up the $MSG macro with the hole content provided by the client via "%hostname% %syslogtag% \"%msg%\"\n". So it's not possible to fill (parse) the desired 'INTERNAL.LOGGING_HOST' variable. How could i achieve, to, get the content of %hostname% (sent by rsyslog) into the 'INTERNAL.LOGGING_HOST' variable of syslog-ng? Thank you! Thomas
