okay bestie, so this is chcpumf — the little tool that manages the CPU-measurement facilities support. That's the whole vibe. Let's get into it 💅

✨ NAME ✨

chcpumf — manage the CPU-measurement facilities support 🎀

---

🦋 SYNOPSIS 🦋

chcpumf [-m|--min NUM_SDB] [-x|--max NUM_SDB] [-V|--verbose]
chcpumf -h|--help
chcpumf -v|--version

no cap, that's the whole shape of it — three ways to call her 👑

---

💖 DESCRIPTION 💖

The chcpumf program helps you to manage settings for the CPU-measurement facilities for Linux on System z. that's literally her entire job and she eats every time ✨

---

🎀 OPTIONS 🎀

• -m, --min NUM_SDB — Specifies the minimum sampling facility buffer size in sample-data-blocks (SDB). A sample-data-block consumes about 4 kilobytes. 🍓

This is the initial buffer size when you start the sampling facility.

• -x, --max NUM_SDB — Specifies the maximum sampling facility buffer size in sample-data-blocks (SDB). A sample-data-block consumes about 4 kilobytes. 🍓

This is the maximum size to which the buffer is dynamically adjusted during sampling.

• -V, --verbose — Displays verbose messages. she's a talker, we love that 🙈
• -h, --help — Displays help information, then exits. 🫶
• -v, --version — Displays version information, then exits. 💜

lowkey important detail: both -m and -x take their size in sample-data-blocks, and each SDB eats about 4 kilobytes. that math is not a vibe checker, it's just facts 🔥
