I want to tell you a story, based on true events. Dave is in his early twenties and he just started his new job as a Systems Engineer in this strange IT company. His ambition is to become the most aspiring and omniscient operator the company has seen. Through his journey of debugging issues and hunting users he learns many things helping him to troubleshoot and improve running systems. Taught to him by his old and wise colleagues. Unfortunately, at some point in his career, Dave reaches a moment where none of the learned techniques can lead him to the solution of this sophisticated problem. What he needs is something that that can display all the data he collects with different tools in one single place. To find answers, he needs to link the data. This story is about how the art of data visualisation can change your whole perspective and help you find the right answers.
