DESCRIPTION

This module defines a simple logger for messages generated by an application. It is intentionally very simple in design, providing the bare minimum in functionality with the possibility for extension by sub-classing.

METHODS

new

This will initialize the base object. It takes the following parameters:

-type

The type of the log. This can be "console", "file", "logstash" or "syslog". Defaults to "console". Which means all logging goes to the current terminal.

-filename

The name of the log file. This only is relevant if the log type is "file".

-facility

The facility of the log message. Primarily has meaning when using a log type of "logstash" or "syslog". The following have been defined and follows the syslog standard.

auth, authpriv, cron, daemon, ftp,
local[0-7], lpr, mail, news, user, uucp

Defaults to "local7".

-process

The name of the process. Defaults to "XAS", which is not to useful.

-levels

A hashref of values to set the internal logging level with.

Example:

my $log = XAS::Lib::Modules::Log->new(
    -levels => {
        debug => $self->debugging ? 1 : 0,
    }
);

This would set the debug level of logging, depending on the value of $self->debugging.

level($level, $boolean)

This will query or toggle the log level. When toggled that particular level is set. There is no hierarchy of log levels.

$level

The log level to toggle. This can be one of the following:

info, warn, error, fatal, debug, trace
$boolean

An optional valve. It needs to be 0 or 1 to set the level.

This method will log an entry with an level of "info".

$line

The message to write out. This can be an array which will be joined with a "space" separator.

$line

The message to write out. This can be an array which will be joined with a "space" separator.
