# Vmstat [![Build Status](https://secure.travis-ci.org/threez/ruby-vmstat.png)](http://travis-ci.org/threez/ruby-vmstat) [![Code Climate](https://codeclimate.com/badge.png)](https://codeclimate.com/github/threez/ruby-vmstat)

This is a focused and fast library to get system information like:

* _Memory_ (free, active, ...)

* _Network Interfaces_ (name, in bytes, out bytes, ...)

* _CPU_ (user, system, nice, idle)

* _Load_ Average

* _Disk_ (type, disk path, free bytes, total bytes, ...)

* _Boot Time_

* _Current Task_ (used bytes and usage time *MAC OS X / Linux ONLY*)

*It currently supports:*

* FreeBSD

* MacOS X

* Linux (>= 2.6)

* OpenBSD

* NetBSD

* Solaris/SmartOS

*It might support (but not tested):*

* Older versions of linux

## Installation

Add this line to your application's Gemfile:

    gem 'vmstat'

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install vmstat

## Usage

Just require the library and make a snapshot or use the distinct methods to just capture parts of the statistics. For further information have a look at the [rdoc](http://rdoc.info/gems/vmstat/frames).

	require "vmstat"

	

	Vmstat.snapshot # => #,

	#	   #,

	#	   #,

	#	   #,

	#	   #,

	#	   #,

	#	   #,

	#	   #],

	#	 @disks=

	#	  [#],

	#	 @load_average=

	#	  #,

	#	 @memory=

	#	  #,

	#	 @network_interfaces=

	#	  [#,

	#	   #,

	#	   #,

	#	   #,

	#	   #],

	#	 @task=

	#	  #>

## Test

Development

	docker-compose up

Single test build and run:

	docker build -t ruby-vmstat .

	docker run --rm -ti ruby-vmstat rake spec

## Todo

* Swap information

* Support more platforms (hp ux, aix, ...)

* Optimize performance for OpenBSD, NetBSD using `uvmexp` etc. directly

* Optimize performance for solaris, smartos using `kstat` etc. directly

* Server performance/system information (open file handles, cache sizes, number of inodes ...)
