Abstract: An end-to-end telemetry system for a Remote Direct Memory Access (RDMA) communication network having multiple end-servers. The system includes an RDMA tracer for each end-server, one or more programmable data planes, and a telemetry collector. Each RDMA tracer extracts host-level telemetry information for one or more RDMA sessions associated with the corresponding end-server. Each programmable data plane extracts network-level telemetry information for one or more RDMA sessions associated with the programmable data plane. The telemetry collector (i) receives the host-level telemetry information from the RDMA tracers and the network-level telemetry information from the one or more programmable data planes and (ii) generates telemetry reports based on the host-level and network-level telemetry information. In some implementations, the system enables real-time monitoring of RDMA traffic at the RDMA protocol level granularity across all RDMA-enabled workloads for different use cases.
