Processing messages stuck in the disk queue files of syslog-ng Premium Edition


When you change the configuration of a syslog-ng PE host that uses disk-based buffering (also called dis queue), syslog-ng PE may start new disk buffer files for the destinations that you have changed. In such case, syslog-ng PE 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.

This document explains the steps required to find, examine, and flush the log messages from such orphaned disk queue files.
