** Syslog(Module)
Included Modules: Syslog::Constants
require 'syslog'
A Simple wrapper for the UNIX syslog system calls that might be handy
if you're writing a server in Ruby. For the details of the syslog(8)
architecture and constants, see the syslog(3) manual page of your
platform.
Module Methods:
open(ident = $0, logopt = Syslog::LOG_PID | Syslog::LOG_CONS,
facility = Syslog::LOG_USER) [{ |syslog| ... }]
Opens syslog with the given options and returns the module
itself. If a block is given, calls it with an argument of
itself. If syslog is already opened, raises RuntimeError.
Example:
Syslog.open('ftpd', Syslog::LOG_PID | Syslog::LOG_NDELAY,
Syslog::LOG_FTP)
open!(ident = $0, logopt = Syslog::LOG_PID | Syslog::LOG_CONS,
facility = Syslog::LOG_USER)
reopen(ident = $0, logopt = Syslog::LOG_PID | Syslog::LOG_CONS,
facility = Syslog::LOG_USER)
Same as open, but does a close first.
opened?
Returns true if syslog opened, otherwise false.
ident
options
facility
Returns the parameters given in the last open, respectively.
Every call of Syslog::open resets these values.
log(pri, message, ...)
Writes message to syslog.
Example:
Syslog.log(Syslog::LOG_CRIT, "the sky is falling in %d seconds!", 10)
crit(message, ...)
emerg(message, ...)
alert(message, ...)
err(message, ...)
warning(message, ...)
notice(message, ...)
info(message, ...)
debug(message, ...)
These are shortcut methods of Syslog::log(). The lineup may
vary depending on what priorities are defined on your system.
Example:
Syslog.crit("the sky is falling in %d seconds!", 5)
mask
mask=(mask)
Returns or sets the log priority mask. The value of the mask
is persistent and will not be reset by Syslog::open or
Syslog::close.
Example:
Syslog.mask = Syslog::LOG_UPTO(Syslog::LOG_ERR)
close
Closes syslog.
inspect
Returns the "inspect" string of the Syslog module.
instance
Returns the module itself. (Just for backward compatibility)
LOG_MASK(pri)
Creates a mask for one priority.
LOG_UPTO(pri)
Creates a mask for all priorities up to pri.
** Syslog::Constants(Module)
require 'syslog'
include Syslog::Constants
This module includes the LOG_* constants available on the system.
Module Methods:
LOG_MASK(pri)
Creates a mask for one priority.
LOG_UPTO(pri)
Creates a mask for all priorities up to pri.
