NAME ^

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

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

METHODS ^

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'.

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'.

avg_memory

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

avg_cache_memory

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

avg_swap_memory

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

avg_swap_free_memory

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

avg_free_memory

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

avg_buffer_memory

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

avg_dirty_memory

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

avg_swap_cache_memory

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