NAME

SDD - Shutdown Daemon

VERSION

Version 0.04

SYNOPSIS

This is the core of the shutdown daemon script.

use SDD;
my $sdd = SDD->new( %args );
$sdd->start();

METHODS

new

Create new instance of SDD

PARAMS

log_file <Str>

Path to log file Default: /var/log/sdd.log'

log_level <Str>

Logging level (from Log::Log4perl). Valid are: DEBUG, INFO, WARN, ERROR Default: INFO

verbose 1|0

If enabled, logging info will be printed to screen as well Default: 0

test 1|0

If enabled shutdown will not actually be executed. Default: 0

sleep_before_run <Int>

Time in seconds to sleep before running the monitors. e.g. to give the system time to boot, and not to shut down before users have started using the freshly started system. Default: 3600

exit_after_trigger 1|0

If enabled will exit the application after a monitor has triggered. Normally it is a moot point, because if a monitor has triggered, then a shutdown is initialised, so the script will stop running anyway. Default: 0

monitor HASHREF

A hash of monitor definitions. Each hash key must map to a Monitor module, and contain a hash with the parameters for the module.

use_sudo 1|0

Use sudo for shutdown

sudo shutdown -h now
