rewrite {

        set("$(* $(/ $R_MIN 5) 5)", value("min_slice"));

        set("0${min_slice}", value("min5"), condition("min_slice" <=  "9"));

        set("${min_slice}",  value("min5"), condition("min_slice" >= "10"));

        # final macro, e.g: www.mytest.com_20170417-1001PM-ng_lua.log.gz

        set("${YEAR}${MONTH}${DAY}-${HOUR12}${min5}${AMPM}", value("logfmt_file"));

        set("${YEAR}${MONTH}${DAY}/${HOUR12}${min5}${AMPM}", value("logfmt_dir"));

    };  

But, does not work with R_MIN values around 1 ~ 9 then never execute the second set(... condition("min_slice" <=  "9")) statement. Has somebody idea?

p.s: I am using the syslog-ng 3.7.3
