PMDAPOSTFIX(1)

✨ PMDAPOSTFIX(1) ✨

okay so bestie, welcome to the General Commands Manual page for pmdapostfix 💅 buckle up

---

🌸 NAME 🌸

pmdapostfix — the Postfix performance metrics domain agent, aka the PMDA 🎀

---

🦋 DESCRIPTION 🦋

so pmdapostfix is a Performance Metrics Domain Agent (that's PMDA, iykyk) and what it does is export mail queue sizes — the ones reported by qshape(1) — plus it also pulls in aggregate statistics collected from mail.log. literally doing the most for your metrics ✨

---

💖 INSTALLATION 💖

if you want access to the names and values for the Postfix performance metrics, do the following as root:

# cd $PCP_PMDAS_DIR/postfix
# ./Install

and to uninstall, the following must be done as root too:

# cd $PCP_PMDAS_DIR/postfix
# ./Remove

ngl there's one thing you gotta know: pmdapostfix is launched by pmcd(1) and should NEVER be executed directly. not even once. the Install and Remove scripts are the ones that notify pmcd(1) when the agent is installed or removed, so let them handle it 👑

---

🎀 FILES 🎀

• $PCP_PMDAS_DIR/postfix/Install — the installation script for the pmdapostfix agent 🫶
• $PCP_PMDAS_DIR/postfix/Remove — the undo installation script for the pmdapostfix agent 🙈
• $PCP_LOG_DIR/pmcd/postfix.log — the default log file for error messages from pmdapostfix 📝

---

🌈 PCP ENVIRONMENT 🌈

environment variables with the prefix PCP_ are used to parameterize the file and directory names used by PCP. 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). so many options, so much power 💜
