|

# Live status dashboard for all continuously running scripts in the ecosystem.
|
||
# Run manually anytime — no schedule, no cron.
|
||
#
|
||
# Covers all scripts started by array_start.sh that run until array stops:
|
||
# system_watchdog.sh — system health monitor
|
||
# docker_watchdog.sh — container health monitor
|
||
# failover.sh — mutual failover monitor
|
||
#
|
||
# Shows for each:
|
||
# Running state, PID, uptime, current cycle
|
||
# Active strikes, skip list, recent actions
|
||
# Live system/container health snapshot
|
||
# Failover state, tier status, Tailscale connectivity
|
||
#
|
||
# If a script is mid-cycle state files are read as-is — reflects last completed cycle.
|
||
# Run: bash Monitors/continuous_scripts_status.sh
