brew install grafana

To have launchd start grafana now and restart at login:
brew services start grafana
Or, if you don’t want/need a background service you can just run:
grafana-server --config=/usr/local/etc/grafana/grafana.ini --homepath /usr/local/share/grafana cfg:default.paths.logs=/usr/local/var/log/grafana cfg:default.paths.data=/usr/local/var/lib/grafana cfg:default.paths.plugins=/usr/local/var/lib/grafana/plugins

Try installing prometheus and prometheus node exporter, it has some system metrics, not sure if node exporter works on Mac OS X t
