Years ago, a buddy hosted corporate email, dns, etc. Racks of servers. He added ambient audio to everything he monitored. Nature sounds, weather, birds, insects, etc. The volume, samples, and tempo would change dynamically. Happy soothing sounds when all was well. Disruptive sounds when bad stuff happened.
(I don't know if you'd classify that as sonification.)
Walking around, visiting with guests, talking on the phone, his crew always knew the health of their systems.
It was awesome.
