[syslog-ng] multi-line logs and program/facility filters

Hi,
Indeed it works with unix-dgram("/dev/log" ); Thanks !

I have another question : I have a system with different packages.
Each package brings its own syslog-ng conf file to define its filters
and log { } blocks. All those conf files are in a directory which is
included by the main syslog-ng conf file.

In the main syslog-ng conf file I want to log all the unfiltered lines
into /var/log/messages.
Problem: I cannot reference previously defined filters without knowing
their name. The main conf file doesn't know those names. Is there a
way to solve this ? Sadly wildcards don't work on filter names...

Regards,
Michael

Make sure you use unix-dgram() in syslog-ng. the system() source in syslog-ng defaults to unix-dgram() if I remember correctly.
