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: o enable/disable various syslog-ng messages for troubleshooting; o 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 An example output: src.internal;s_all#0;;a;processed;6445 src.internal;s_all#0;;a;stamp;1268989330 destination;df_auth;;a;processed;404 destination;df_news_dot_notice;;a;processed;0 destination;df_news_dot_err;;a;processed;0 destination;d_ssb;;a;processed;7128 destination;df_uucp;;a;processed;0 source;s_all;;a;processed;7128 destination;df_mail;;a;processed;0 destination;df_user;;a;processed;1 destination;df_daemon;;a;processed;1 destination;df_debug;;a;processed;15 destination;df_messages;;a;processed;54 destination;dp_xconsole;;a;processed;671 dst.tcp;d_network#0;10.50.0.111:514;a;dropped;5080 dst.tcp;d_network#0;10.50.0.111:514;a;processed;7128 dst.tcp;d_network#0;10.50.0.111:514;a;stored;2048 destination;df_syslog;;a;processed;6724 destination;df_facility_dot_warn;;a;processed;0 destination;df_news_dot_crit;;a;processed;0 destination;df_lpr;;a;processed;0 destination;du_all;;a;processed;0 destination;df_facility_dot_info;;a;processed;0 center;;received;a;processed;0 destination;df_kern;;a;processed;70 center;;queued;a;processed;0 destination;df_facility_dot_err;;a;processed;0
