I'm using syslog-ng to collect logs from different devices and everything is Ok - all log files and directories are created and being written, except syslog log files - they are just empty (e.g. /var/log/hostname/syslog size is zero). Here is my config: monitoring:~# cat /etc/syslog-ng/syslog-ng.conf @version: 3.0 # # Syslog-ng configuration file, compatible with default Debian syslogd # installation.

Later I used 2.x version of syslog-ng and everything worked. -- С уважением, Андрей.
