You know, if I worked at Amazon, I would be very tempted to build something that plays river-and-rainforest sounds to indicate the health status of things.

Smoothly running stream? Everything is green. Rapids? Yellow-status; something needs looking into. Waterfall? Something's gone terribly awry.

Happily chirping birds? Successful health checkins. Monkeys screeching? Unhealthy result. Jaguar growl? Datacenter is on fire.
