NAME

NetSDS::Logger - syslog wrapper for applications and classes

SYNOPSIS

         use NetSDS::Logger;
 
         my $logger = NetSDS::Logger->new(
                 name => 'NetSDS-SuperDaemon',
         );
         $logger->log("info", "Syslog message here");
 
 

DESCRIPTION

This module contains implementation of logging functionality for NetSDS components.

By default, messages are logged with "local0" facility and "pid,ndelay,nowait" options.

NOTE: "NetSDS::Logger" module is for internal use mostly from application frameworks like "NetSDS::App", "NetSDS::App::FCGI", etc.

CLASS API

new(%parameters) - constructor

Constructor new() creates new logger object and opens socket with default NetSDS logging parameters.

Arguments allowed (as hash):

name - application name for identification

         Use only ASCII characters in "name" to avoid possible errors.
         Default value is "NetSDS".
 
 

facility - logging facility

         Available facility values:
 
                 * local0..local7
                 * user
                 * daemon
 
         If not set 'local0' is used as default value
 
 

log($level, $message) - write record to log

Wrapper to "syslog()" method of Unix::Syslog module.

Level is passed as string and may be one of the following:

         alert   - LOG_ALERT
         crit    - LOG_CRIT
         debug   - LOG_DEBUG
         emerg   - LOG_EMERG
         error   - LOG_ERR
         info    - LOG_INFO
         notice  - LOG_NOTICE
         warning - LOG_WARNING
 
 

DESTROY - class destructor

Destructor (DESTROY method) calls "closelog()" function. That's all.

See NetSDS::App for example.
