Enabling normal disk-based buffering

Every destination driver supports the disk-buffer() option. The network(), syslog(), tcp(), and tcp6() destination drivers can also use the disk-buffer option, except when using the udp transport method.

If the reliable() option is not set, by default a normal disk-buffer is created. To explicitly enable the normal disk-buffer option, use the disk-buffer(reliable(no)) parameter in the destination. Use the normal disk-buffer option if you want a solution that is faster than the reliable disk-buffer option. In this case, the process will be less reliable and it is possible to lose logs in case of AxoSyslog crash. The filename of the normal disk-buffer file is the following: <syslog-ng path>/var/syslog-ng-00000.qf.

Example: Example for using normal disk-based buffering

When using the disk-buffer plugin:

   destination d_BSD {
