[syslog-ng] Program() in destination driver not working for Macros defined in CSV-PARSER

Hello On My Apache logs I applied csv_parser() and defined the Macros. parser p_apache { csv-parser(columns("apache.ETSTAMP", "apache.TYPE", "apache.EHOSTNAME","apache.ESOURCE", "apache.EOUTCOME", "apache.EMSG","apache.EUSERID") delimiters("|") ); }; I want to launch a script whenever the UDP messages are in.So I defined the destination d_mesg (program("/tmp/test.sh" template("|${apache.ETSTAMP}|${apache.TYPE}|${apache.EHOSTNAME}|${apache.ESOURCE}|${apache.EOUTCOME}|${apache.EMSG}|${apache.EUSERID}\n")); }; script is working fine with other destination drivers. Please help -- Kale
