Monitoring is the best way to give team members a good night's sleep. No one wants to be woken up in the morning by a call from an angry supervisor: "The system is not working; fix it now!". Granted, monitoring doesn't just help restful sleep but relatively quick feedback from real users. After all, we all strive for feedback in agile teams. With monitoring, real and fast feedback becomes possible, where tests only allow it with a lot of effort or are not feasible at all.
