"In light of recent events on the tracing tools side of Linux, some reflections came to mind which I would like to share with the Linux community. It is my hope that my perspective and experience as a maintainer of an open-source project called the Linux Trace Toolkit (LTT) and as a consultant in the open-source field may be helpful to others in understanding how the open-source movement is evolving."
"I started developing the Linux Trace Toolkit in the beginning of 1999 as part of my research at the Ecole Polytechnique de Montreal ("Poly"). I had one purpose: to provide a way for users to understand the dynamic behavior of a complex operating system -- in this case, Linux. From the start, I was convinced that numbers and lists of items were insufficient to described such systems. Instead, what was needed was a way to visually illustrate the system's behavior."
"As the old adage says, a picture is worth a thousand words. Many ideas came to mind, but right from the start the one that seemed to make the most sense was a control-graph similar to the one currently displayed by LTT. Hence, I started out with a very clear idea of what I expected of this tool once it was running."
