=head1 NAME

IBM::StorageSystem::Statistic::Node::Memory - Utility class for IBM::StorageSystem node memory statistics

=head1 SYNOPSIS

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

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

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

start_time end_time avg_memory avg_cache_memory avg_swap_memory avg_swap_free_memory avg_free_m    emory avg_buffer_memory avg_dirty_memory avg_swap_cache_memory

=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 avg_memory

The average memory available (in KB) during the interval period.  B<Note> that this appears to always be
equal to the total amount of memory for the specified node.

=head3 avg_cache_memory

The average memory (in KB) dedicated to cache in the interval period.

=head3 avg_swap_memory

The average memory (in KB) dedicated to swap during the interval period.  B<Note> that this value always
appears to be equal to the total amount of memory dedicated to swap on the specified node.

=head3 avg_swap_free_memory

The average amount of free swap memory (in KB) during the interval specified.

=head3 avg_free_memory

The average amount of free memory (in KB) during the interval period.

=head3 avg_buffer_memory

The average amount of memory (in KB) dedicated to buffers during the interval period.

=head3 avg_dirty_memory

The average amount of memory (in KB) marked as dirty (in KB) during the interval period.

=head3 avg_swap_cache_memory

The average amount of memory (in KB) dedicated to swap cache during the interval period.
