〇構築方法
1. 以下のVagrantfileを使用して、GrafanaとPrometheusをインストールした仮想マシン(Ubuntu16.04)を構築します

Vagrantfile

VAGRANTFILE_API_VERSION = "2"

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
  config.vm.box = "bento/ubuntu-16.04"
  config.vm.hostname = "ub1604grafanaprometheus"
  config.vm.provider :virtualbox do |vbox|
     vbox.name = "ub1604grafanaprometheus"
     vbox.cpus = 4
     vbox.memory = 4096
     vbox.customize ["modifyvm", :id, "--nicpromisc2","allow-all"]
  end
config.vm.network "private_network", ip: "192.168.55.108", :netmask => "255.255.255.0"
config.vm.network "public_network", ip:"192.168.1.108", :netmask => "255.255.255.0"
