Autonomous NGINX Reflex Agent
Self-healing. Port-aware. Silence-proof.
Built for uptime. Born inside MatrixSwarm.
When your edge goes dark — it answers.

📦 Overview
nginx-sentinel is a swarm-grade watchdog agent. It monitors NGINX like a reflex, detects daemon failure or port silence, restarts instantly, and logs every cycle with precision.

It doesn’t check.
It knows.
It doesn’t wait.
It reacts.

✅ Features
Checks nginx.service via systemd

Verifies ports 80 and 443 are actively listening

Auto-restarts NGINX on failure or unbound port

Sends .msg alerts to comm agents like Discord or Telegram

Tracks uptime, downtime, and restart count per day

Cooldown protection via should_alert()

Reflex fires on DOWN and RECOVERED transitions only

📣 Example Swarm Alerts

📣 Swarm Alert
❌ Nginx is DOWN or not binding required ports.

📣 Swarm Alert
✅ Nginx has recovered and is now online.
📁 Log Output
Uptime logs written daily to:

/comm/nginx-sentinel/uptime_YYYY-MM-DD.log

💬 Codex Drop
The first line of defense isn’t a firewall.
It’s a reflex.
nginx-sentinel listens for port silence like a gunshot in the dark.
And when it hears it… it pulls the trigger.
