[syslog-ng] db-parser reuse for multiple logs?

[Evan Rempel]

I don't have an answer to your actual question, however, you can work around it by

log {
         source(src_udp);
         parser(myparser);
         log {
                 filter(filter_host1);
                 destination(dst_host1);
                 flags(final);
         };
         log {
                 filter(filter_host2);
                 destination(dst_host2);
                 flags(final);
         };
};

Hope that helps.

Evan.
