Claim 14:
15. A machine-implemented method for a centralized telemetry collector of a distributed, end-to-end RDMA telemetry system for a distributed RDMA network comprising multiple, distributed end-servers, the method comprising the centralized telemetry collector:
receiving, from multiple, distributed RDMA tracers of the system, each distributed RDMA tracer inside a different, distributed end-server, transparently extracted host-level telemetry information on RDMA-related application activities for one or more RDMA sessions associated with the multiple, distributed end-servers;
receiving, from one or more programmable data planes, RDMA-specific network-level telemetry state information extracted from encapsulated RDMA packets for the one or more RDMA sessions associated with the multiple, distributed end-servers, wherein each different programmable data plane is either inside an end-server of the network or outside of all of the end-servers of the RDMA network; and
processing the transparently extracted host-level telemetry information and the RDMA-specific network-level telemetry state information to generate external telemetry reports, wherein, for an RDMA session of the one or more RDMA sessions, the RDMA session involving a source end-server and a destination end-server, the telemetry collector builds end-to-end telemetry at an RDMA protocol level by combining (i) host-level tracing results, (ii) RDMA session detection results, and (iii) network-level telemetry information.
