Sankey flow diagrams have long been an important feature of Kentik Detect, used to represent the flow of network data from hop to hop. We’ve recently refined the calculations underlying our Sankeys related to performance metrics, such as percent retransmits or latencies, to give a more accurate picture of these metrics. Our Sankeys also now support bracketing, which enables the coloring of nodes — and the links between them — based on your bracket specifications, which is very useful for performance diagrams.
