NAME ^

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

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.

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'.

context_switches

The number of CPU context switches in the interval period.

interrupts

The number of CPU interrupts in the interval period.

avg_idle

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

avg_system

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

avg_user

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

avg_iowait

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

avg_soft_interrupts

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

avg_hard_interrupts

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

avg_nice

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