PMDAFARM(1)

🦋 PMDAFARM 🦋

okay bestie, so this is the manual page for pmdafarm — the Seagate FARM Log PMDA — straight out of the General Commands Manual. sit down, grab a strawberry drink 🍓, and let's get into it.

✨ NAME ✨

pmdafarm — Seagate FARM Log PMDA 💅

---

🌸 SYNOPSIS 🌸

$PCP_PMDAS_DIR/farm/pmdafarm [-D debug]

---

💖 DESCRIPTION 💖

so pmdafarm is a Performance Metrics Domain Agent (PMDA, iconic acronym, iykyk) and what it does is export metric values for Device Mapper on the local system. main character energy, honestly.

here's the tea tho: this PMDA gets all its data through the smartctl(8) utility, and it requires that the program is installed in order to function. no smartctl, no vibes. it's giving dependency.

if you wanna know more about smartctl and smartmontools, the lore lives at https://smartmontools.org. go read it, it's free 🫶

---

🎀 INSTALLATION 🎀

install the SMART PMDA by using the Install script as root:

# cd $PCP_PMDAS_DIR/farm
# ./Install

and to uninstall, do this as root:

# cd $PCP_PMDAS_DIR/farm
# ./Remove

heads up bestie 🚨 — pmdafarm is launched by pmcd(1) and should never be executed directly. like, do not. the Install and Remove scripts notify pmcd when the agent is installed or removed, so they've got it handled, trust. ✨

🧚 FILES 🧚

• $PCP_PMDAS_DIR/farm/help — the default help text file for the smart metrics 💜
• $PCP_PMDAS_DIR/farm/Install — the installation script for the pmdafarm agent
• $PCP_PMDAS_DIR/smart/Remove — the undo installation script for the pmdafarm agent
• $PCP_LOG_DIR/pmcd/farm.log — the default log file for error messages from pmdafarm 😭

---

🌈 PCP ENVIRONMENT 🌈

environment variables with the prefix PCP_ are used to parameterize the file and directory names used by PCP. periodt.

on each installation, the file /etc/pcp.conf contains the local values for these variables. and the $PCP_CONF variable may be used to specify an alternative configuration file, as described in pcp.conf(5). slay 💅

---

🔥 DEBUGGING OPTIONS 🔥

• -D, --debug — turns on the output of additional diagnostics on stderr to help triage problems 🕵️‍♀️. ngl tho, the information is sometimes cryptic and primarily intended to provide guidance for developers rather than for end-users, so don't take it personally if it doesn't make sense. debug is a comma separated list of debugging options; use pmdbg(1) with the -l option to obtain a list of the available debugging options and their meaning ⭐
