=head1 NAME
Net::Server::Log::Sys::Syslog - log via Syslog
=head1 SYNOPSIS
use base qw(Net::Server::PreFork);
__PACKAGE__->run(
log_file => 'Sys::Syslog',
syslog_ident => 'myapp',
);
=head1 DESCRIPTION
This module provides Sys::Syslog logging to the Net::Server system.
=head1 CONFIGURATION
=over 4
=item log_file
To begin using Sys::Syslog logging, simply set the Net::Server
log_file configuration parameter to "Sys::Syslog".
If the magic name "Sys::Syslog" is used, all logging will take place
via the Sys::Syslog module. If syslog is used the parameters
C<syslog_logsock>, C<syslog_ident>, and C<syslog_logopt>,and
C<syslog_facility> may also be defined.
=item syslog_logsock
Only available if C<log_file> is equal to "Sys::Syslog". May be
either unix, inet, native, console, stream, udp, or tcp, or an
arrayref of the types to try. Default is "unix" if the version of
Sys::Syslog < 0.15 - otherwise the default is to not call setlogsock.
See L<Sys::Syslog>.
=item syslog_ident
Only available if C<log_file> is equal to "Sys::Syslog". Id to
prepend on syslog entries. Default is "net_server". See
L<Sys::Syslog>.
=item syslog_logopt
Only available if C<log_file> is equal to "Sys::Syslog". May be
either zero or more of "pid","cons","ndelay","nowait". Default is
"pid". See L<Sys::Syslog>.
=item syslog_facility
Only available if C<log_file> is equal to "Sys::Syslog". See
L<Sys::Syslog> and L<syslog>. Default is "daemon".
=back
=head1 DEFAULT ARGUMENTS FOR Net::Server
The following arguments are available in the default C<Net::Server> or
C<Net::Server::Single> modules. (Other personalities may use
additional parameters and may optionally not use parameters from the
base class.)
Key Value Default
## syslog parameters (if log_file eq Sys::Syslog)
syslog_logsock (native|unix|inet|udp
|tcp|stream|console) unix (on Sys::Syslog < 0.15)
syslog_ident "identity" "net_server"
syslog_logopt (cons|ndelay|nowait|pid) pid
syslog_facility \w+ daemon
=head1 METHODS
=over 4
=item C<initialize>
This method is called during the initilize_logging method of
Net::Server. It returns a single code ref that will be stored under
the log_function property of the Net::Server object. That code ref
takes log_level and message as arguments and calls the initialized
log4perl system.
=item C<handle_log_error>
This method is called if the log_function fails for some reason. It
is passed the Net::Server object, the error that occurred while
logging and an arrayref containing the log level and the message. In
turn, this calls the legacy Net::Server::handle_syslog_error method.
