PMDACIFS(1)

💖 pmdacifs 💖

okay bestie, welcome to the manual page for pmdacifs — it lives in section 1 of the General Commands Manual, and it's genuinely one of those little guys that does a lot 💅

---

✨ NAME ✨

pmdacifs — the Common Internet Filesystem (CIFS) PMDA 🫶

---

🌸 SYNOPSIS 🌸

$PCP_PMDAS_DIR/cifs/pmdacifs [-D debug]

---

🦋 DESCRIPTION 🦋

So pmdacifs is a Performance Metrics Domain Agent (PMDA) — and no, that's not a scary word, it just means it's the little agent that hands performance metrics over to the rest of the PCP crew ✨

Specifically, it exports metric values about mounted CIFS shares, pulling them straight out of the /proc/fs/cifs directory. iykyk 🌈

Two things it needs to actually do its job, and I need you to hear me on this:

• The CIFS kernel module has to be loaded — at minimum — to return some metric values.
• You need at least one mounted CIFS share in order to get data for all the metrics.

So like… no mount, no full data. it's giving "empty plate at the function" 😭

---

🎀 INSTALLATION 🎀

Installing the CIFS PMDA is a root situation, bestie. Use the Install script:

# cd $PCP_PMDAS_DIR/cifs
# ./Install

And when you want it gone — uninstall time, no hard feelings — this also has to be done as root:

# cd $PCP_PMDAS_DIR/cifs
# ./Remove

⚠️ Important, and I mean it: pmdacifs is launched by pmcd(1) and should never be executed directly. Let the daemon do its thing, okay? 🙈

The Install and Remove scripts are the ones that notify pmcd when the agent gets installed or removed — so they're handling the communication for you, you don't have to 👑

---

💜 FILES 💜

• $PCP_PMDAS_DIR/cifs/help — the default help text file for the CIFS metrics 📄
• $PCP_PMDAS_DIR/cifs/Install — the installation script for the pmdacifs agent ⭐
• $PCP_PMDAS_DIR/cifs/Remove — the undo-installation script for the pmdacifs agent 🌙
• $PCP_LOG_DIR/pmcd/cifs.log — the default log file for error messages from pmdacifs 📝

---

🌈 PCP ENVIRONMENT 🌈

Environment variables that start with the prefix PCP_ are the ones that parameterize the file and directory names PCP uses — so that's the naming system in play here 🧚

On every installation, the file /etc/pcp.conf holds the local values for these variables. And if you want a different configuration file, you can point the $PCP_CONF variable at it — pcp.conf(5) explains all that if you wanna go deeper 💫

---

🔥 DEBUGGING OPTIONS 🔥

• -D, --debug — turns on extra diagnostics printed to stderr, which helps triage problems. Fair warning though: the info is sometimes cryptic and is primarily meant to guide developers rather than end-users 😅 debug is a comma separated list of debugging options — and to see the available debugging options and what they mean, run pmdbg(1) with the -l option.
