[syslog-ng] get destination(s) based on log facility and severity

Hi, We have a kind of machinery which collects syslog logs from several hosts. Currently it works by sending a message using logger(1) to the given facility.severity and then looking up the message in log files in /var/log and a few other directories (using grep). I'm looking for a more robust and faster way to discover the destination. Would that be possible with syslog-ng? And which is the optimal way to achieve that? An extra syslog-ng option? An extra binary? Or perhaps using logger(1)? Cheers, Dejan
