HA_LOGD(8)

📦 version 1.0.12, in debian bookworm, debian trixie, ubuntu jammy, ubuntu noble, ubuntu questing, ubuntu resolute, ubuntu stonking

✨ NAME ✨

okay so bestie, let me put you on: ha_logd — the Logging Daemon for High-Availability Linux. that's the whole vibe. it logs. it daemonizes. it's iconic. 💅

🦋 SYNOPSIS 🦋

ha_logd [-s] [-k] [-d] [-h] [-c file]

💖 DESCRIPTION 💖

so ha_logd is a logging daemon for Linux-HA, and honestly? it's the friend who holds your stuff so you don't have to. it receives messages from a local domain socket at /var/lib/heartbeat/log_daemon, and writes them to the appropriate files — plus syslog if you've enabled that. 🌸

now why does this whole daemon situation even exist, you ask? because occasionally Heartbeat suffers from disk I/O delays 😭 and that's not the energy we're bringing. by sending log messages off to a logging daemon instead, heartbeat can dodge those I/O delays entirely. it's giving delegating, and we love a queen who delegates. 👑

✨ OPTIONS ✨

here's everything it supports, no gatekeeping:

  • -s — show ha_logd status, so either running or stopped. vibe check, basically. 🔍
  • -k — stop (kill) the daemon. it's over bestie, say goodbye 💀
  • -d — daemonize. and listen: without this option, ha_logd will run in the foreground, which means it's just… there. watching. main character behavior in your terminal.
  • -h — show a brief usage message. your little "help me" moment, we've all been there 🫶
  • -c file — configuration file. you can configure a regular log file, a debug log file, a log facility, and an entity with this. for the deets, go look at the example ha_logd.cf file chillin' in the documentation. 📁

🎀 FILES 🎀

  • /run/ha_logd.pid – PID file. it's where the daemon's lil ID lives 🪪
  • ha_logd.cf – example configuration file. copy the fit, make it your own ✨
