Description

A Ruby interface for gathering various bits of information about your CPU.

Synopsis

   
   require "sys/cpu"
   include Sys

   # Solaris
   puts "Mhz: " + CPU.cpu_freq(0).to_s
   puts "State: " + CPU.state(0)
   puts "Number of cpu's on this system: " + CPU.num_cpu.to_s
   puts "CPU type: " + CPU.type
   puts "FPU type: " + CPU.fpu_type
   puts "CPU model: " + CPU.model
   puts "Load averages: " + CPU.load_avg.join(", ")
   

Constants

VERSION

Returns the current version number for this package.

Class Methods

CPU.freq(cpu_num=0)

Returns an integer indicating the speed (i.e. frequency in Mhz) of 'cpu_num', or CPU 0 if no number is provided.

CPU.type

Returns a string indicating the type of processor. This is the architecture (e.g. sparcv9), not the exact model (e.g. Ultra-IIe). Returns nil if not found.

CPU.fpu_type

Returns a string indicating the type of floating point unit, or nil if not found.

CPU.load_avg

Returns an array of three floats indicating the 1, 5 and 15 minute load average.

CPU.model

Returns a string indicating the cpu model. For now, this is the architecture type, rather than the exact model. However, see the 'Future Plans' section below.

CPU.num_cpu

Returns an integer indicating the number of cpu's on the system.

CPU.state(cpu_num)

Returns a string indicating the cpu state of 'cpu_num'.

Error Classes

CPU::Error < StandardError

Raised is response to internal function errors, usually relating to an invalid cpu number.

Known Bugs

None known. Please post bug reports to the SourceForge home page at http://www.rubyforge.org/projects/sysutils

Future Plans

Add more information, such as what prtdiag shows.
Get the model() method to display more specific information.
