One missing item is instrumentation and metrics. Understanding and debugging a complex application is made much easier by having an abundance of easily collectable metrics that describe the running or cumulative state of the system.

Being alerted to potential (or actual) problems can allow an admin to respond to them effectively, rather than trying to patch things together after it's hit the fan.
