SYNOPSIS

10       syslog-ng-ctl [command] [options]
11

DESCRIPTION

13       NOTE: The syslog-ng-ctl application is distributed with the system
14       logging application, and is usually part of the syslog-ng package. The
15       latest version of the syslog-ng application is available at the
16       official syslog-ng website[1].
17
18       This manual page is only an abstract, for the complete documentation of
19       syslog-ng, see The Administrator Guide[2].
20
21       The syslog-ng-ctl application is a utility that can be used to:
22
23       •   enable/disable various syslog-ng messages for troubleshooting
24
25       •   display statistics about the processed messages
26
27       •   reload the configuration of .
28

ENABLING TROUBLESHOOTING MESSAGES

30       command [options]
31
32       Use the syslog-ng-ctl <command> --set=on command to display verbose,
33       trace, or debug messages. If you are trying to solve configuration
34       problems, the verbose (and occasionally trace) messages are usually
35       sufficient. Debug messages are needed mostly for finding software
36       errors. After solving the problem, do not forget to turn these messages
37       off using the syslog-ng-ctl <command> --set=off. Note that enabling
38       debug messages does not enable verbose and trace messages.
39
40       Use syslog-ng-ctl <command> without any parameters to display whether
41       the particular type of messages are enabled or not.
42
43       If you need to use a non-standard control socket to access syslog-ng,
44       use the syslog-ng-ctl <command> --set=on --control=<socket> command to
45       specify the socket to use.
46
47       verbose
48           Print verbose messages. If syslog-ng was started with the --stderr
49           or -e option, the messages will be sent to stderr. If not
50           specified, syslog-ng will log such messages to its internal source.
51
52       trace
53           Print trace messages of how messages are processed. If syslog-ng
54           was started with the --stderr or -e option, the messages will be
55           sent to stderr. If not specified, syslog-ng will log such messages
56           to its internal source.
57
58       debug
59           Print debug messages. If syslog-ng was started with the --stderr or
60           -e option, the messages will be sent to stderr. If not specified,
61           syslog-ng will log such messages to its internal source.
62
63       Example:
64
65           syslog-ng-ctl verbose --set=on
66

THE STATS COMMAND

68       stats [options]
69
70       Use the stats command to display statistics about the processed
71       messages. The stats command has the following options:
72
73       --control=<socket> or -c
74           Specify the socket to use to access syslog-ng. Only needed when
75           using a non-standard socket.
76
77       --reset or -r
78           Reset all statistics to zero, except for the stored counters. (The
79           stored counters show the number of messages stored in the message
80           queue of the destination driver, waiting to be sent to the
81           destination.)
82
83       Example:
84
85           syslog-ng-ctl stats
86
87       An example output:

RELOADING THE CONFIGURATION

118       command [options]
119
120       Use the syslog-ng-ctl reload command to reload the configuration file
121       of without having to restart the application. The syslog-ng-ctl reload
122       works like a SIGHUP.
