=head1 NAME
Nagios::Plugin::Threshold - class for handling Nagios::Plugin thresholds.
=head1 SYNOPSIS
# NB: This is an internal Nagios::Plugin class.
# See Nagios::Plugin itself for public interfaces.
# Constructor
$t = Nagios::Plugin::Threshold->set_thresholds(
warning => $warning_range_string,
critical => $critical_range_string,
);
# Value checking - returns CRITICAL if in the critical range,
# WARNING if in the warning range, and OK otherwise
$status = $t->get_status($value);
# Accessors - return the associated N::P::Range object
$warning_range = $t->warning;
$critical_range = $t->critical;
=head1 DESCRIPTION
Internal Nagios::Plugin class for handling threshold data. See
Nagios::Plugin for public interfaces.
A threshold object contains (typically) a pair of ranges, associated
with a particular severity e.g.
warning => range1
critical => range2
