I'm trying to parse log messages that are received from a udp port and insert them into a MYSQL database. My destination in my syslog-ng.conf file is as follows:source syslog_udp {    udp(port(<port num>) flags(no-parse));};The parser I have written is as follows:parser p_logparser{    csv-parser(columns(<column1>, <column2>, ...)    flags(strip-whitespace)    delimiters(,)    template(${<column1}\n)    );};I am also using a filter to discard a certain part of the log message:filter log_filter { not (match(<string>) and match(<string>));};Ultimately, I want to be able to write the contents of column1 into a MYSQL database, but for testing purposes I am currently writing to a file:destination d_file {            file(<path>/${ISODATE} template(Testing : ${column1}));};log {            source(syslog_udp);            parser(p_logparser);            filter(log_filter);            destination(d_file);};However, when I open the file that's described in d_file, all I can see is Testing :  and the contents of column1 aren't actually there. I have a feeling it is because my parser is not creating the soft macros properly. What am I doing wrong? 
soft-macros are empty in csv parser
syslog;syslog ng
