=head1 NAME

IBM::StorageSystem::Statistic::Node::CPU - Utility class for IBM::StorageSystem node CPU statistics

=head1 SYNOPSIS

IBM::StorageSystem::Statistic::Node::CPU is a utility class for IBM::StorageSystem node CPU statistics.

An IBM::StorageSystem::Statistic::Node::CPU object represents a collection of statistical measurements for
CPU activity for the specified node during a single interval period.  

The interval period is defined by the interval parameter passed on invocation to the specific parent class.

=head1 METHODS

=head3 start_time 

The start time of the interval over which the data was collected in the format 'YYYY-MM-DD HH:MM:SS UTC+HH'.

=head3 end_time 

The end time of the interval over which the data was collected in the format 'YYYY-MM-DD HH:MM:SS UTC+HH'.

=head3 context_switches 

The number of CPU context switches in the interval period.

=head3 interrupts 

The number of CPU interrupts in the interval period.

=head3 avg_idle 

The average percentage of CPU time spent idle during the interval period.

=head3 avg_system

The average percentage of CPU time spent in kernel space during the interval period.

=head3 avg_user 

The average percentage of CPU time spent in user space during the interval period.

=head3 avg_iowait 

The average percentage of CPU time spent waiting on IO during the interval period.

=head3 avg_soft_interrupts 

The average percentage of CPU time spent handling software interrupts during the interval period.

=head3 avg_hard_interrupts 

The average percentage of CPU time spent handling hardware interrupts during the interval period.

=head3 avg_nice

The average percentage of CPU time spent on low priority processes during the interval period.
