[syslog-ng] variable host filter in events

[Balazs Scheidler]

Hi,

You can extract values from $MSG by using regexps (by using a regexp based
filter with the flags(store-matches) option), or by using csv-parser() with
a  custom separator (this should be faster) or even db-parser. In any case,
once you extracted the server name just make sure to store it in $HOST and
then you can use $HOST in your destination filename.
