Grafana is the web frontend to view the monitoring logs which are provided by prometheus. Prometheus periodically polls the output of Prometheus Node Exporter, both of which runs as systemd service.

There are different exporters for different kind of services, like exporters for Apache, Nginx, MySQL / MariaDB, etc.
