〇MySQL Server ExporterのデータをPrometheusで表示した画面
〇構築方法
以下のVagrantfileを使用して、MySQL Server Exporter(Prometheus)とMariaDBをインストールした仮想マシン(Ubuntu18.04)を構築します
Vagrantfile

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|

config.vm.provider :virtualbox do |vbox|
vbox.name = "ub1804mariadbmysqlexporter"
vbox.cpus = 2
vbox.memory = 2048
vbox.customize ["modifyvm", :id, "--nicpromisc2","allow-all"]
end
