node_exporter is a utility that export node information via prometheus API. It takes care of host related metrics such as CPU and memory. The install script, download the node_exporter binaries, create a link in /usr/bin. On OS with systemd supported it would enable and start the installed service file to start as a service. On others (ubuntu) it would create a conf file and start it. The installation should be done using sudo. After a successful installation, the node_exporter would run as a service.
