usage statistics.

=head1 SYNOPSIS

	# Print all blades in all chassis along with a cacti-style listing of 
	# the blades current, minimum and maximum power consumption values.

	map { 
		print "Chassis: " . $_->id ."\n";

		map { print "\tBlade: ". $_->id ." - Power consumed -"
			  . " Current:". $_->power_stats->consumed_power 
			  . " Max:". $_->power_stats->consumed_power_max 
			  . " Min:". $_->power_stats->consumed_power_min ."\n" 
		} 
		sort { $a->id <=> $b->id } $_->get_blades

	} 
	sort { 
		$a->id <=> $b->id 
	} $ucs->get_chassiss;

	# Prints something like:
	#
	# Chassis: 1
	#	Blade: 1 - Power consumed - Current:115.656647 Max:120.913757 Min:110.399513
	#	Blade: 2 - Power consumed - Current:131.427994 Max:139.313675 Min:126.170883
	#	Blade: 3 - Power consumed - Current:131.427994 Max:157.713593 Min:126.170883
	#	Blade: 4 - Power consumed - Current:0.000000 Max:0.000000 Min:0.000000
	#	Blade: 5 - Power consumed - Current:0.000000 Max:0.000000 Min:0.000000

=head1 DESCRIPTION

Cisco::UCS::Common::PowerStats is a class providing operations with a Cisco 
UCS power usage statistics.

Note that you are not supposed to call the constructor yourself, rather a 
Cisco::UCS::Common::PowerStats object is created automatically by method calls 
on a L<Cisco::UCS::Blade> object.

=head1 METHODS

=head3 consumed_power

Returns the current power consumed value for the blade.

=head3 consumed_power_avg

Returns the current average power consumed value for the blade.

=head3 consumed_power_min

Returns the current minimum power consumed value for the blade.

=head3 consumed_power_max

Returns the current maximum power consumed value for the blade.

=head3 input_current

Returns the current input current value for the blade.

=head3 input_current_avg

Returns the current average input current value for the blade.

=head3 input_current_min

Returns the current minimum input current value for the blade.

=head3 input_current_max

Returns the current maximum input current value for the blade.

=head3 input_voltage

Returns the current input voltage value for the blade.

=head3 input_voltage_avg

Returns the current average input voltage value for the blade.

=head3 input_voltage_min

Returns the current minimum input voltage value for the blade.

=head3 input_voltage_max

Returns the current maximum input voltage value for the blade.

=head3 thresholded

Returns the input power thresholded state for the blade.

=head3 suspect

Returns the input power suspect state for the blade.

=head3 time_collected

Returns the timestamp at which time the power statsitics were collected.
