== Description
Sys::CPU - An interface for various cpu statistics
== Synopsis
require "sys/cpu"
include Sys
puts "Mhz: " + CPU.cpu_freq.to_s
puts "State: " + CPU.state(0)
puts "Number of cpu's on this system: " + CPU.num_cpu.to_s
puts "Number of active cpu's: " + CPU.num_active_cpu.to_s
puts "Load averages: " + CPU.load_avg.join(", ")
== Constants
VERSION
Returns the current version number for this package.
== Class Methods
CPU.architecture
Returns the cpu architecture, e.g. PA RISC 1.2, etc.
CPU.freq(cpu_num=0)
Returns an integer indicating the speed (i.e. frequency in Mhz) of
the cpu.
CPU.load_avg
CPU.load_avg(cpu_num)
CPU.load_avg{ |cpu| ... }
In non-block form returns an array of three floats indicating the 1, 5
and 15 minute overall load average.
In block form, it returns an array of three floats indicating the 1, 5
and 15 minute load average for each cpu. Only useful on multi-cpu
systems.
If 'cpu_num' is provided, returns the load average (as a 3-element
array) for that cpu only.
You cannot provide a cpu number and use block form at the same time.
CPU.num_cpu
Returns an integer indicating the number of cpu's on the system.
CPU.num_active_cpu
Returns an integer indicating the number of active cpu's on the system.
== Error Classes
CPU::Error < StandardError
Raised is response to internal function errors, usually relating to an
invalid cpu number.
