SYSLOG-NG-CTL(1)

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

SYNOPSIS

syslog-ng-ctl [command] [options]

DESCRIPTION

NOTE: The syslog-ng-ctl application is distributed with the syslog-ng 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 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 validate command to validate the signatures and timestamps of a logstore file. The validate 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
