NAME
courierlogger - Courier syslog wrapper
SYNOPSIS
courierlogger [ -name=title ] [
courierlogger [ -name=title ] [
-facility=subsystem ] [ -pid=filename ]
[ [ -respawn ] -start program [ argument
... ] | -stop | -restart ]
DESCRIPTION
courierlogger is a wrapper that captures another
process's error messages, and forwards them to the system logging
facility, ``syslog''.
There are two ways to use courierlogger:
- 1.
- Use the shell to pipe another command's standard error, and/or
its standard output, to courierlogger's standard input.
- 2.
- Alternatively, courierlogger itself can start another
process, and arrange to have its standard error captured.
In either case, each read line of text is sent as a syslog
message.
OPTIONS
- -name=title
- -name=title
- Use title for sending messages to syslog. title
- Use title for sending messages to syslog. title
should be the application's name.
- -facility=subsystem
- Use subsystem for classifying messages. Your syslog
facility uses subsystem to determine which log messages are
recorded in which log files. The currently defined subsystems are:
-
- *
- auth
- *
- authpriv
- *
- console
- *
- cron
- *
- daemon
- *
- ftp
- *
- kern
- *
- lpr
- *
- mail
- *
- news
- *
- security
- *
- user
- *
- uucp
- *
- local0
- *
- local1
- *
- local2
- *
- local3
- *
- local4
- *
- local5
- *
- local6
- *
- local7
- Note: Not all of the above facility names are
implemented on every system. Check your system's syslog
documentation for information on which facility names are allowed,
and which log files record the corresponding messages for each
facility.
- -pid=filename
- Save courierlogger's process ID in filename. The
-pid option is required when -start, -stop,
-restart.
- -start program [argument...]
- Start program, and capture its standard error.
Otherwise, courierlogger reads message from standard input,
and automatically terminated when standard input is closed. If the
start option is given program will be started as a
child process of courierlogger, capturing its standard
error.
The pid option is required. courierlogger will
quietly terminate if another courierlogger process is
already running. This is used to make sure that only one instance
of program is running at the same time. Specify a different
filename with pid to start a second copy of program.
- -respawn
- Restart program if it terminates. Normally
courierlogger itself will terminate when program
finishes running. Use respawn to restart it instead.
- -restart
- Send a SIGHUP signal to program. Does nothing if
program is not running (as determined by examining the
contents of the file specified by pid).
- Note: program must be originally started with the
respawn option.
The same thing may be accomplished by sending SIGHUP to
courierlogger itself.
- -stop
- Send a SIGTERM signal to program. If program does
not terminate in ten seconds, kill it with SIGKILL. Does nothing if
program is not running in the first place (as determined by
examining the contents of the file specified by
pid).
