NAME

       syslog-ng-ctl - Display message statistics and enable verbose, debug and trace modes in

SYNOPSIS

       syslog-ng-ctl [command] [options]

DESCRIPTION

       NOTE: The syslog-ng-ctl application is distributed with the 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
       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

       •   reload the configuration of .

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 verbose (and occasionally
       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.

       --reset or -r
           Reset all statistics to zero, except for the stored counters. (The stored counters
           show the number of messages stored in the message queue of the destination driver,
           waiting to be sent to the destination.)

       Example:

           syslog-ng-ctl stats

       An example output:

           src.internal;s_all#0;;a;processed;6445

RELOADING THE CONFIGURATION

       command [options]

       Use the syslog-ng-ctl reload command to reload the configuration file of without having to
       restart the application. The syslog-ng-ctl reload works like a SIGHUP.
