A real-time TUI monitor for RDMA network interfaces.
Script Preview
Review this script before executing in your terminal.
rdmatop is a Linux TUI for monitoring RDMA network interfaces in real time through RDMA netlink.
It tracks Gbps, packet rates, drops, RDMA reads and writes, retransmits and health events. It also maps queue pairs to PIDs and process details from /proc.
When profiling GPU communication, recording mode writes Chrome JSON traffic traces for Perfetto, and the refresh interval can be changed live.
HPC engineers, GPU infrastructure teams and Linux administrators can inspect RDMA traffic during benchmarks, cluster tests and production troubleshooting.
