ZIOMON_ZFCPDD(8)

💅 ZIOMON_ZFCPDD(8) — like, the ziomon_zfcpdd manual page, bestie

okay so this is ziomon_zfcpdd from section 8 of the manual (that's the sysadmin/system-stuff section, iykyk), and honestly? she's niche but she's doing the work. let's get into it 🫶

✨ NAME ✨

ziomon_zfcpdd — monitor zfcp through blktrace drv_data traces 🦋

like, that's the whole vibe. she watches zfcp, she reads the drv_data traces, she's a monitor. no cap.

---

🎀 SYNOPSIS 🎀

ziomon_zfcpdd [ -v ] [ -V ] [ -h ] [ -i interval ] [ -b file ] [ -Q
msgq_path -q msgq_id -m msg_id ]

look at that little line of flags. iconic. every single one of those brackets is optional, but the -Q / -q / -m trio literally travels as a group — note how they're all chillin' inside the same brackets 💅

---

🌸 DESCRIPTION 🌸

ziomon_zfcpdd monitors performance relevant data provided by the zfcp device driver — and the specific things she's clocking are channel und fabric latency, plus QDIO outbound queue utilisation. yes, "und" — that's what the original says, we're not fixing it, we're respecting it 💖

she periodically writes statistics, and the way that works is: every time a user-specified interval elapses, out come the stats. (the original says "user-sepcified," which, again — we're preserving, not correcting. periodt. 😭)

and where do these traces come from? ziomon_zfcpdd consumes zfcp drv_data traces provided by the binary output of blktrace. so like, she's not out there scooping data herself, she's receiving it. main character energy but make it collaborative ✨

💅 OPTIONS 💅

• -h, --help — print usage information, then exit. the classic "wait what does this do again" move 🎀
• -v, --version — print version information, then exit. she tells you who she is and dips 🦋
• -V, --verbose — be verbose. yes queen, say more 💬
• *-i *interval, --interval interval — specify interval length in seconds. this is the heartbeat, bestie ⏱️
• *-b *file, --binary file — specify the filename for binary output. that's where the goods go 🍓
• *-Q *msgq_path, --msg-queue msgq_path — specify the message queue path name. the address of the group chat 📬
• *-q *msgq_id, --msg-queue-id msgq_id — specify the message queue id. which group chat, specifically 🔑
• *-m *msg_id, --msg-id msg_id — specify the message id to use. the actual message label 💌

ngl, -v and -V are literally one shift key apart and they do completely different things. one says hi and leaves, the other makes her chatty. do not mix them up unless you're in the mood for chaos 💀
