Getting the status information of disk-buffer files

Purpose

This section describes getting the status information of the disk-buffer files used in AxoSyslog.

Command syntax

The basic command syntax for getting the status information of the disk-buffer files used in AxoSyslog looks like the following:

   /opt/syslog-ng/bin/dqtool info DISK-BUFFER_FILE

Example commands

The following example commands describe how you can get the status information of two different types of disk-buffer files (namely, empty normal disk-buffer files, and non-empty reliable disk-buffer queue files).

Example commands for empty, normal disk-buffer files, and non-empty, reliable disk-buffer queue files

• Empty, normal disk-buffer file

      /opt/syslog-ng/bin/dqtool info /opt/syslog-ng/var/syslog-ng-00000.qf/var/lib/syslog-ng/syslog-ng-00000.qfDisk-buffer state loaded; filename='/opt/syslog-ng/var/syslog-ng-00000.qf/var/lib/syslog-ng/syslog-ng-00000.qf', number_of_messages='0'
  

• Non-empty, reliable disk-buffer queue file

      /opt/syslog-ng/bin/dqtool info /opt/syslog-ng/var/syslog-ng-00000.rqfReliable disk-buffer state loaded; filename='/opt/syslog-ng/var/syslog-ng-00000.rqf', number_of_messages='10'
  

One-liner command to get the state of disk-buffer files in the default directory

You can use the following one-liner command to get the state of disk-buffer files in the default directory:

   for qfile in /opt/syslog-ng/var/*.?(r)qf ; do /opt/syslog-ng/bin/dqtool info $qfile 2>&1 ; done
