Getting the status information of disk-buffer files

This section describes how to get 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 and outputs

• 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.qf
  

  Example output:

  Disk-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.rqf
  

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

List disk-buffer state in the default directory

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

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