ATOP-DAILY(1)

💖 atop-daily(1) — the daily glow-up your PCP archives deserve 💖

okay bestie, welcome to the General Commands Manual section of the vibes, where atop-daily lives. she's a shell script, she's booked and busy, and she handles the daily maintenance of your pcp-atop(1) PCP archives. no cap. 🎀

✨ SYNOPSIS ✨

$PCP_BINADM_DIR/atop-daily [--compress-only] [--help] [LOGPATH]

---

🌸 DESCRIPTION 🌸

so like, atop-daily does the daily maintenance of pcp-atop(1) PCP archives. she's not out here freelancing — she's normally called from systemd(1) via the atop-daily.timer unit, or she gets summoned automatically by pcp-atop(1) itself at startup. she's that girl who shows up when the timer goes off, periodt. ⏰💅

when you run her with no options at all, she:

1. creates the archive directory if it's not there yet (manifesting it into existence ✨)
2. compresses prior-day archives — xz(1) for the metadata, zstd(1) for the data volumes (different tools for different jobs, we love a specialist 💜)
3. culls archives that are older than LOGGENERATIONS days (default 28) — old archives, you're done here, thank u next 🙈

and here's the iconic part: compression is non-blocking. files get atomically renamed and then compressed by background processes, so the caller and pcp-atop(1) can just keep it moving immediately. nobody's waiting around in this group chat. 💫

---

💅 OPTIONS 💅

• --compress-only — compress prior-day archives and that's IT, she will not cull old archives. this is the mode used when pcp-atop(1) itself calls her at startup. culling? not today. 🚫🗑️
• --help — prints a usage message and dips. short, sweet, iconic. 🫶

---

🦋 CONFIGURATION 🦋

you can set these environment variables in the pcp-atop(1) sysconfig file, which lives at /etc/sysconfig/atop or /etc/default/atop (whichever one your system is serving 🍓):

• LOGPATH — the archive directory. default: /var/log/atop. you can ALSO pass this as a command line argument instead, so flexible of her. 🌈
• LOGGENERATIONS — how many days of archives to keep around. default: 28. and listen: a value of 0 disables culling entirely. zero means never let go, i guess 😭💀

---

🎀 FILES 🎀

• /var/log/atop — the default directory where pcp-atop(1) archive files hang out. it's giving home base. 👑
