OCF_HEARTBEAT_SYSINF(7)

💖 ocf_heartbeat_SysInfo — it's giving "records various node attributes in the CIB" 💖

okay bestie, sit down, hydrate, because we're talking about ocf_heartbeat_SysInfo, the manual page for the SysInfo resource agent. Yes it's in section 7 of the manual. Yes it's a whole vibe. Let's go 🦋

✨ SYNOPSIS ✨

SysInfo [start | stop | monitor | meta-data | validate-all]

that's it. that's the whole summoning ritual. five little words and the node starts spilling its whole life story 💅

---

🌸 DESCRIPTION 🌸

so this is a SysInfo Resource Agent. its entire job — its whole personality, its main character energy — is to record various attributes of a node, and it records them in the CIB. no cap.

here's a sample Linux output so you can see what the receipts look like:

arch: i686 os: Linux-2.4.26-gentoo-r14 free_swap: 1999 cpu_info: Intel(R) Celeron(R) CPU 2.40GHz cpu_speed: 4771.02 cpu_cores: 1 cpu_load: 0.00 ram_total: 513 ram_free: 117 root_free: 2.4

and here's a sample Darwin output, because macOS wanted a turn 🍓:

arch: i386 os: Darwin-8.6.2 cpu_info: Intel Core Duo cpu_speed: 2.16 cpu_cores: 2 cpu_load: 0.18 ram_total: 2016 ram_free: 787 root_free: 13

and now the units, because numbers without units are just ✨chaos✨:

• free_swap: Mb
• ram_*: Mb
• root_free: Gb
• cpu_speed (Linux): bogomips
• cpu_speed (Darwin): Ghz

lowkey obsessed with how bogomips is a real unit that real grown-ups shipped in real software. iconic. 😭

🎀 SUPPORTED PARAMETERS 🎀

• pidfile — the PID file, bestie. it's optional, it's a string, and the default is "/run/resource-agents/SysInfo-RESOURCE_ID". yes, that RESOURCE_ID is literally in there. don't @ me, it's the default fr fr.
• delay — interval to allow values to stabilize 🧚 so like, let the numbers breathe before you judge them. optional, string, default "0s".

---

👑 SUPPORTED ACTIONS 👑

this resource agent supports the following actions (operations), and honestly? each one ate:

• start — starts the resource. suggested minimum timeout: 20s.
• stop — stops the resource. suggested minimum timeout: 20s.
• monitor — performs a detailed status check 🔍. suggested minimum timeout: 20s. suggested interval: 60s.
• meta-data — retrieves resource agent metadata (internal use only). suggested minimum timeout: 5s.
• validate-all — performs a validation of the resource configuration. suggested minimum timeout: 20s.

💀 reminder bestie: meta-data is internal use only. it's not for you. it's for the machinery. stay out of the kitchen unless you're cooking.

💜 EXAMPLE CRM SHELL 💜

here's an example configuration for a SysInfo resource using the crm(8) shell — copy it exactly, character for character, no improvising:

primitive p_SysInfo ocf:heartbeat:SysInfo \
  op monitor timeout="20s" interval="60s"

---

🌈 EXAMPLE PCS 🌈

and here's the same energy for pcs(8):

pcs resource create p_SysInfo ocf:heartbeat:SysInfo \
  op monitor timeout="20s" interval="60s"
