NAME

Sys::CpuLoadX - a module to retrieve system load averages.

SYNOPSIS

use Sys::CpuLoadX;
print '1 min, 5 min, 15 min load average: ',
     join(',', Sys::CpuLoadX::load()), "\n";
print "Best estimate of current load = ", Sys::CpuLoadX::get_cpu_load(), "\n";

FUNCTIONS

@loads = Sys::CpuLoadX::load()

Retrieves the 1 minute, 5 minute, and 15 minute load average of a machine.

$load = Sys::CpuLoadX::get_cpu_load()

Returns the best estimate of the current system load. For Unix like systems, this is the 1 minute load average like the one returned from uptime(1), and measures the average number of active processes that are competing for CPU time. For Windows machines (include Cygwin), it is computed from a one second sample of the CPU load, and is a value between 0 and 1 representing the fraction of CPU utilization during that second.

This function will return -1 if it cannot determine a suitable method for finding the CPU load on the system.
