# ================================= System Watchdog ============================================
|
|
# ==============================================================================================
|
|
# Thin orchestrator — runs SYSTEM_WATCHDOG_SCRIPTS from master.conf sequentially.
|
|
# Called by watchdog_orchestrator.sh each cycle. Covers system component health:
|
|
# storage pool growth, runaway logs, WebGUI availability, and network connectivity.
|
|
#
|
|
# ── EXECUTION ORDER ───────────────────────────────────────────────────────────────────────────
|
|
# Driven by SYSTEM_WATCHDOG_SCRIPTS in master.conf — add, remove, or reorder there.
|
|
# Default: storage_watchdog → webgui_watchdog → network_watchdog
|
|
#
|
|
# ── SEQUENTIAL EXECUTION ─────────────────────────────────────────────────────────────────────
|
|
# All scripts run in the foreground. Each must complete before the next starts.
|
|
# A failed script is logged but does not prevent remaining scripts from running.
|
|
#
|
|
# ── SAFEGUARDS ────────────────────────────────────────────────────────────────────────────────
|
|
# Root check — child scripts require root
|
|
# acquire_lock — prevents concurrent system watchdog runs
|
|
# detect_hosts() — MY_ID in notifications and logs
|
|
# Non-fatal steps — a failed step is logged; remaining steps still run
|
|
#
|
|
# ── CONFIGURATION (master.conf) ───────────────────────────────────────────────────────────────
|
|
# SYSTEM_WATCHDOG_SCRIPTS — ordered list of system component watchdog scripts to run
|
|
#

|
# ── USAGE ─────────────────────────────────────────────────────────────────────────────────────

|
# system_watchdog.sh — run all system component watchdogs
|
|
# system_watchdog.sh --dry-run — preview without running anything
|
|
# system_watchdog.sh --status — show configured scripts and exit
|
