Vnstat is a tool that tracks the traffic on your network interfaces. This tiny library is intended to provide network traffic information through an easy-to-use API.
It depends on the vnstat command line utility which is maintained by Teemu Toivola.
- Ruby 2.3.0 or greater
- Make sure you have
vnstatCLI installed by runningwhich vnstat.
On Ubuntu you can get the vnstat package via apt-get install vnstat.
Once the dependent package is installed, you are ready to install the vnstat-ruby gem.
gem install vnstat-rubyOr, add the following line to the Gemfile of your project and run the
bundle install command:
gem 'vnstat-ruby'By default, vnstat-ruby tries to automatically determine the location of your vnstat executable. If you need to change this path for some reason, you can override the default:
Vnstat.config.executable_path = '/usr/bin/vnstat'To retrieve a list of all known network interfaces:
Vnstat.interfaces # => #<Vnstat::InterfaceCollection ...>
Vnstat.interfaces.ids # => ['eth01', 'eth02']To only retrieve traffic stats for a single interface:
Vnstat.interfaces.first # => #<Vnstat::Interface id: "eth01">If you know the name of a network interface, you can also retrieve the stats of that particular one:
Vnstat['eth01'] # => #<Vnstat::Interface id: "eth01">interface = Vnstat['eth01']interface.total # => #<Vnstat::Result ...>
interface.total.bytes_received # => 1024000
interface.total.bytes_sent # => 2048000
interface.total.bytes_transmitted # => 3072000interface.months # => #<Vnstat::Traffic::Monthly ...>interface.months.first
interface.months[2015, 9]
# => #<Vnstat::Result::Month year: 2015, month: 9, ...>interface.months[2015, 10].bytes_received # => 3072000interface.days # => #<Vnstat::Traffic::Daily ...>interface.days.first
interface.days[Date.new(2015, 11, 23)]
interface.days[2015, 11, 23]
# => #<Vnstat::Result::Day date: #<Date: 2015-11-23>, ...>interface.days[2015, 11, 23].bytes_received # => 2048000interface.hours # => #<Vnstat::Traffic::Hourly ...>interface.hours.first
interface.hours[Date.new(2015, 9, 22), 10]
interface.hours[2015, 9, 22, 10]
# => #<Vnstat::Result::Hour date: #<Date: 2015-11-23>, hour: 10>interface.hours[2015, 9, 22, 10].bytes_received # => 2048000interface.tops #=> #<Vnstat::Traffic::Tops ...>
interface.tops.count #=> 10
interface.tops.each do |top|
# ...
endinterface.tops.first
interface.tops[2]
# => #<Vnstat::Result::Minute time: 2015-11-05 09:03:42 +0000>interface.tops[1].bytes_received # => 1024000- Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet.
- Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it.
- Fork the project.
- Start a feature/bugfix branch.
- Commit and push until you are happy with your contribution.
- Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
- Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
