Now let's move to the Prometheus dashboard and update the sub-path /graph and /alerts (framed in yellow at the top left of the image) a few times (15-20 times should be enough), in order to activate the rules adopted.

After a few minutes, if no other http requests are made, these alerts will return to the starting status, i.e. inactive. The Watchdog alert, at the top of the screenshot, is always present: is an alert meant to ensure that the entire alerting pipeline is functional.
