@badnetmask yep! So tells you when there’s a failure.
Weeks later, you have not seen any failure messages but you look manually anyway & discover that the monitoring system itself has been failing & thus, no notification.
So you modify the monitoring system to notify you of success & failure, both.
Weeks later you are numb to the success messages so you haven’t really been paying attention, but you look and discover that there have been repeated failure messages you ignored. 😒
