NAME
Event::RPC::Logger - Logging facility for Event::RPC SYNOPSIS
use Event::RPC::Server; use Event::RPC::Logger; my $server = Event::RPC::Server->new ( ... logger => Event::RPC::Logger->new( filename => "/var/log/myserver.log", fh_lref => [ $fh, $sock ], min_level => 2, ), ... ); $server->start; DESCRIPTION
This modules implements a simple logging facility for the Event::RPC framework. Log messages may be written to a specific file and/or a bunch of filehandles, which may be sockets as well. CONFIGURATION OPTIONS
This is a list of options you can pass to the new() constructor: filename All log messages are appended to this file. fh_lref All log messages are printed into this list of filehandles. min_level This is the minimum log level. Output of messages with a lower level is suppressed. This option may be altered using set_min_level() even in a running server. METHODS
$logger->log ( [$level, ] $msg ) The log() method does the actual logging. Called with one argument the messages gets the default level of 1. With two argumens the first is the level for the message. $logger->add_fh ( $fh ) This adds a filehandle to the internal list of filhandles all log messages are written to. $logger->remove_fh ( $fh ) Removes a filehandle.
