Codebase-wide audit pass: fixed real bugs (SSH hangs missing BatchMode, local-outside-function no-ops, variable name collisions, a truncated ratio calc, wrong state-dir path, DARK vs NO_INTERNET drift, and more), then pulled logic that was duplicated across multiple scripts — arr cleanup safety gates, docker restart ordering, container maintenance stop/restart, watchdog state-file helpers, partnership role resolution, cert expiry checks, remote node discovery, and TMDB discovery scoring — into common.sh so each now has a single implementation.

# ==============================================================================================
|
|
#
|
|
# PURPOSE
|
|
# ─────────────────────────────────────────────────────────────────────────────
|
|
# Full ecosystem health aggregation from existing state files. Scheduled daily
|
|
# (8am). DIGEST_PROFILE controls when notifications actually send — the cron
|
|
# schedule never changes, only the profile in master.conf.
|
|
#
|
|
# Reads state files from across the system (watchdog strikes, fallback state,
|
|
# skip list, bandwidth history, transcode stats, cert status) and compiles them
|
|
# into a single digest. Reads only — writes nothing, changes nothing.
|
|
#
|
|
# ==============================================================================================
|
|
# DESIGN PRINCIPLES
|
|
# ==============================================================================================
|
|
#
|
|
# Aggregator, Not Generator
|
|
# This script reads state files that other scripts maintain. It never produces
|
|
# health data itself — it only presents what is already there. Each source
|
|
# script remains responsible for its own state; this script is the envelope.
|
|
#
|
|
# Profile-Driven Notification
|
|
# The cron schedule never changes. The DIGEST_PROFILE in master.conf controls
|
|
# when notifications actually send — switching from daily noise to weekly
|
|
# summaries is a one-line conf change, not a cron edit.
|
|
#
|
|
# Read-Only, No Side Effects
|
|
# Writes nothing, changes nothing, triggers nothing. Safe to run at any time
|
|
# for a health snapshot without affecting any running service or state file.
|
|
#
|
|
# ==============================================================================================
|
|
# OPERATIONAL MODEL
|
|
# ==============================================================================================
|
|
#
|
|
# Three profiles — switch by changing DIGEST_PROFILE in master.conf:
|
|
#
|
|
# always — sends every run regardless of findings
|
|
# Use: daily digest of everything, even when healthy
|
|
#
|
|
# smart — sends only when something worth reporting was found
|
|
# Stays silent on clean days. DIGEST_SMART_ON_* toggles control
|
|
# what triggers a send — all independently configurable.
|
|
#
|
|
# weekly — sends once per week on DIGEST_DAY (default Sunday), silent all other days
|
|
# Use: one weekly summary without daily noise
|
|
#
|
|
# Data sources (reads only):
|
|
# FALLBACK_STATE_FILE — current fallback state
|
|
# DOCKER_WATCHDOG_FAILED_FILE — container skip list (manual intervention needed)
|
|
# WATCHDOG_STATE_FILE — active container watchdog strikes
|
|
# SYS_WATCHDOG_STATE_FILE — active system watchdog strikes
|
|
# BANDWIDTH_LOG — yesterday's transfer totals
|
|
# TRANSCODE_DAILY_LOG — weekly transcode statistics
|
|
# CERT_MONITOR_DOMAINS — live SSL cert check via openssl
|
|
# RAMDISK_PATH / TRANSCODE_LINK — current transcode location and usage
|
|
#
|
|
# ==============================================================================================
|
|
# OPERATIONAL SAFEGUARDS
|
|
# ==============================================================================================
|
|
#
|
|
# Single Instance Lock
|
|
# acquire_lock prevents duplicate reports — report generation takes time.
|
|
#
|
|
# Per-Host Variables
|
|
# detect_hosts() aliases CERT_MONITOR_DOMAINS, RAMDISK_WARN_GB, RAMDISK_SIZE,
|
|
# RAMDISK_LOW_GB, and all other host-specific vars used in the report.
|
|
#
|
|
# Per-Section Guards
|
|
# Each data source section checks whether its state file exists before reading.
|
|
# A missing state file is skipped cleanly — it does not abort the report.
|
|
#
|
|
# Silent Smart Profile
|
|
# smart profile produces no output and no notification when nothing worth
|
|
# reporting is found.
|
|
#
|
|
# Notifications Validated
|
|
# platform_require_cmd confirms notify and openssl are present before use.
