Step – 5 : Restart the Prometheus to apply changes
root@linuxhelp:~# systemctl restart prometheus
Step – 6 : Check the Prometheus status by using the following command
root@linuxhelp:~# systemctl status prometheus

Q
How does Prometheus collect data?
A
Prometheus has multiple methods for collecting data:
Scraping: Prometheus pulls data from web servers using HTTP or other protocols.
Push: Applications push metrics directly to Prometheus.
Pull: Prometheus fetches metrics from other systems, like databases or message queues.
