There is this magic sense of confidence you get when a status dashboard is all green. Suddenly, a highly complex system with dozens or hundred of modules, is saying ‘well, so far so good’. Visually alive in front of you, showing how many users are connected, how many transactions are being generated and how many resources are used to serve all that.
Otherwise, the only way you’ll find out when something is wrong, is that angry customer’s call notifying that your system is down, and you didn’t know. Not anyone’s idea of a happy day.
