If you need help, want to open a support ticket, or report a bug, we recommend using the syslog-ng-debun tool to collect information about your environment and syslog-ng OSE version. For details, see The syslog-ng-debun manual page. For support contacts, see About us.
When you change the configuration of a syslog-ng OSE host that uses disk-based buffering (also called disk queue), syslog-ng OSE may start new disk buffer files for the destinations that you have changed. In this case, syslog-ng OSE abandons the old disk queue files. If there were unsent log messages in the disk queue files, these messages remain in the disk queue files, and will not be sent to the destinations.
Security-Enhanced Linux (SELinux) is a set of kernel and user-space tools enforcing strict access control policies. SELinux rules in Linux distributions cover all aspects of the syslog-ng configuration coming in the syslog-ng package available in the distribution. But as soon as an unusual port number or directory name is specified in the configuration, syslog-ng fails to work even with a completely legitimate configuration.
When you choose to save logs of a central syslog-ng OSE server to a directory other than the /var/log directory, logs will not start appearing on the newly configured directory. For details on how to fix this issue, see section

By default, SELinux only allows connections to the default syslog ports. When you have to use any other port for some reason, sending logs to that port will not work. For details on how to fix this issue, see section
