I'd argue that unexpected restarts should alert beyond a threshold. Alerting on every occurrence is too noisy. If an individual unit failure causes a service disruption architecture improvements are needed.

Don't you want to know if something restarts unexpectedly? It's a bug that should be understood and fixed. (If it's not a bug then it's not unexpected.)
