NAME
syslog-ng-ctl - Display message statistics and enable verbose, debug and trace modes in syslog-ng Open
Source Edition
SYNOPSIS
syslog-ng-ctl [command] [options]
DESCRIPTION
NOTE: The syslog-ng-ctl application is distributed with the syslog-ng Open Source Edition system logging
application, and is usually part of the syslog-ng package. The latest version of the syslog-ng
application is available at the official syslog-ng website[1].
This manual page is only an abstract; for the complete documentation of syslog-ng, see The syslog-ng Open
Source Edition Administrator Guide[2].
The syslog-ng-ctl application is a utility that can be used to:
• enable/disable various syslog-ng messages for troubleshooting;
• display statistics about the processed messages.
ENABLING TROUBLESHOOTING MESSAGES
command [options]
Use the syslog-ng-ctl <command> --set=on command to display verbose, trace, or debug messages. If you are
trying to solve configuration problems, the debug (and occassionally trace) messages are usually
sufficient; debug messages are needed mostly for finding software errors. After solving the problem, do
not forget to turn these messages off using the syslog-ng-ctl <command> --set=off. Note that enabling
debug messages does not enable verbose and trace messages.
Use syslog-ng-ctl <command> without any parameters to display whether the particular type of messages are
enabled or not.
If you need to use a non-standard control socket to access syslog-ng, use the syslog-ng-ctl <command>
--set=on --control=<socket> command to specify the socket to use.
verbose
Print verbose messages. If syslog-ng was started with the --stderr or -e option, the messages will be
sent to stderr. If not specified, syslog-ng will log such messages to its internal source.
trace
Print trace messages of how messages are processed. If syslog-ng was started with the --stderr or -e
option, the messages will be sent to stderr. If not specified, syslog-ng will log such messages to
its internal source.
debug
Print debug messages. If syslog-ng was started with the --stderr or -e option, the messages will be
sent to stderr. If not specified, syslog-ng will log such messages to its internal source.
Example:
syslog-ng-ctl verbose --set=on
THE STATS COMMAND
stats [options]
Use the stats command to display statistics about the processed messages. The stats command has the
following options:
--control=<socket> or -c
Specify the socket to use to access syslog-ng. Only needed when using a non-standard socket.
Example:
syslog-ng-ctl stats
