💖 rdmaucma(8) — System Manager's Manual 💖

✨ NAME ✨

okay so the tool is rdmaucma, and its whole job is to trace RDMA UCMA (Userspace Connection Manager Access) events 🦋. For Linux, it runs on BCC and eBPF. 💅

🎀 SYNOPSIS 🎀

rdmaucma [-h] [-D]

🌸 DESCRIPTION 🌸

bestie, this program watches RDMA UCMA (Userspace Connection Manager Access) events as they happen ✨. It's seriously useful when you need to figure out what's going wrong with RDMA CM 😭🫶.

🙈 Heads up: since this tool runs on BPF, only the root user can use it. No cap, you'll need root.

📋 REQUIREMENTS 📋

you'll need CONFIG_BPF enabled in your kernel, plus bcc installed 🔥.

👑 OPTIONS 👑

• -h — slide in and ask for the usage message 💜
• -D — show the debug info for the BPF text 🧚

🍓 SOURCE 🍓

this tool comes from bcc 🌈. You can grab it here: https://github.com/iovisor/bcc

also, dig through the bcc distribution for a companion _examples.txt file. It has example usage, output, and commentary for this tool, and it's giving full tutorial energy 📖✨.

🧚 OS 🧚

it's Linux only, so no other OS is invited to this party 🐧.

🔥 STABILITY 🔥

lowkey, it's Unstable - in development 🙈. Expect things to change, so don't be shocked if it shifts on you 💀.
