cargo build\nmake install # cargo install\n```\n\n## Usage\n\n```bash\nrdmatop\n```\n\n## Examples\n\nUse `rdmatop` to monitor RDMA traffic while running GPU\ncommunication benchmarks:\n\n- [NCCL](examples/nccl/) — collective communication\n- [NIXL](examples/nixl/) — point-to-point KV cache transfer\n- [NVSHMEM](examples/nvshmem/) — one-sided GPU communication\n- [PPLX Kernels](examples/pplx/) — MoE all-to-all dispatch/combine\n- [RDMA Statistics](examples/rdma/) — shell-based RDMA stats\n- [Kubernetes](examples/kubernetes/) — DaemonSet deployment for Kubernetes\n\n## How It Works\n\n1. **Device enumeration** — `RDMA_NLDEV_CMD_GET` via netlink to discover all RDMA devices\n2. **HW counters** — `RDMA_NLDEV_CMD_STAT_GET` per device/port, same as `rdma statistic show`\n3. **Process detection** — `RDMA_NLDEV_CMD_RES_QP_GET` to map QPs → PIDs, enriched with `/proc` data\n4. **Throughput** — Two snapshots per interval, delta / elapsed for rates\n\n## License\n\nApache-2.0\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcrazyguitar%2Frdmatop","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fcrazyguitar%2Frdmatop","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcrazyguitar%2Frdmatop/lists"}
