I'm having to revisit what alarms and alerts i should pay attention to. What would you say are a must alarms, notifications, and alerts for monitoring the network using Observability platform and what are the difference in your point of view. As of now, I'm getting email notifications that tell me when a device is down, when the backup is successful, and if there were any changes detected which i think is good but i was told perhaps its too many notifications and we should consider only the important ones.
