In this video from the 2019 OpenFabrics Workshop in Austin, Jason Gunthorpe from Mellanox presents: Debug and Diagnostics.

"Every technology requires tools for debug and diagnostic and RDMA is no different. As deployment becomes wider and
as technology is being used by various users with various levels of expertise, the need for easy to manage debug and
diagnostic tools becomes more essential. Many tools are helping to debug RDMA. Some tools are not “solely” for RDMA
debug. Such tools are ethtool, ip link (iproute2 package) for checking and configuring ethernet and IP layer and tcp
dump for capturing traffic. Some tools are RDMA specific. The new evolving rdmatool provides socket monitoring, RDMA
counters and is a home for other RDMA configuration and monitoring. In addition, traffic generators for RDMA allow
testing of utilization and latency. On top of that end to end monitoring helps to monitor and sanitized network issues. In
this talk I’ll review the tools above and will focus on RDMA related tools, current state and going forward/"
