摘要: We explore the nature of traffic in data centers, designed to support mining massive sets. instrument servers collect socket-level logs, with negligible performance impact. In a 1500 server operational cluster, we thus amass roughly petabyte measurements over two months, from which obtain and report detailed views congestion conditions patterns. further consider whether matrices cluster might be obtained instead via tomographic inference coarser-grained counter data.
