PMDASNMP(1)

💅 PMDASNMP — the SNMP-to-PCP gateway, bestie edition 💅

okay so this is pmdasnmp(1), straight out of the Performance Co-Pilot manual, and I'm gonna explain it to you like we're texting at 1am 🦋

✨ NAME ✨

pmdasnmp — literally a gateway from SNMP to PCP, and it's a PMDA (a Performance Metrics Domain Agent, iykyk) 💖

---

🌸 DESCRIPTION 🌸

So pmdasnmp is a Performance Metrics Domain Agent (PMDA, iconic acronym, no cap). What does it actually do? It's a generic gateway — it takes the PCP queries coming in from a PCP client and turns them into SNMP queries going out to one or more SNMP agents. That's the whole vibe. PCP in, SNMP out, bestie, it's giving translator 🫶

---

🎀 INSTALLATION 🎀

Want access to the SNMP gateway performance metrics? Then do this as root, bestie — root, not your regular little user account:

# cd $PCP_PMDAS_DIR/snmp
# ./Install

Changed your mind and wanna undo the whole thing? Also as root:

# cd $PCP_PMDAS_DIR/snmp
# ./Remove

Now the important part, and I need you to actually read this one 🔥 — pmdasnmp gets launched by pmcd(1) and should never be executed directly. Like, never ever. The Install and Remove scripts are the ones that go tell pmcd(1) that the agent got installed or removed, so it handles all that for you. Let the scripts cook 💅

⭐ CONFIGURATION ⭐

TODO: define config file format here - map/set/host/... etc

That's it. That's the section. It's a TODO, the config file format is not defined here yet, so don't come for me, I'm just the messenger 😭

🦋 FILES 🦋

• $PCP_PMDAS_DIR/snmp/snmp.conf — optional configuration file for pmdasnmp. Optional!! It's optional, so you can but you don't have to ✨
• $PCP_PMDAS_DIR/snmp/Install — the installation script for the pmdasnmp agent
• $PCP_PMDAS_DIR/snmp/Remove — the undo-installation script for the pmdasnmp agent
• $PCP_LOG_DIR/pmcd/snmp.log — the default log file where all the error messages and warn() messages from pmdasnmp land. So when something's wrong, this is where you go snooping 👀

I have no notes. It lives there now. 💀
