        // Trigger restart via PM2 API or webhook
    }
}

// Check setiap 5 menit
setInterval(healthCheck, 5 * 60 * 1000);

Monitoring & Alerts

Setup Uptime Monitoring:

TOOLS GRATIS:
- UptimeRobot (50 monitors free)
- Freshping (50 monitors free)
- Cronitor (limited free)

SETUP:
1. Buat endpoint /health di bot
2. Daftarkan URL di monitoring tool
3. Set alert ke email/Telegram
4. Dapat notif jika bot down

Health Endpoint:

javascript

const express = require('express');
const app = express();

let lastMessageTime = Date.now();
let isConnected = false;

app.get('/health', (req, res) => {
    const status = {
        connected: isConnected,
        lastMessage: new Date(lastMessageTime).toISOString(),
        uptime: process.uptime(),
        memory: process.memoryUsage()
    };
    
    if (isConnected) {
        res.status(200).json({ status: 'healthy', ...status });
    } else {
        res.status(503).json({ status: 'unhealthy', ...status });
    }
});

app.listen(3000);

Auto-Recovery

PM2 Auto-Restart:

javascript

// ecosystem.config.js
module.exports = {
    apps: [{
        name: 'wa-bot',
        script: 'index.js',
        watch: false,
        max_memory_restart: '500M',

Tips 24/7 Reliability

1. Redundancy

Primary: VPS di Singapore
Backup: VPS di Jakarta

Jika primary down, switch ke backup.
Atau gunakan load balancer.

2. Graceful Reconnection

javascript

sock.ev.on('connection.update', async (update) => {
    const { connection, lastDisconnect } = update;
    
    if (connection === 'close') {
        const shouldReconnect = 
            lastDisconnect?.error?.output?.statusCode !== 401;
        
        if (shouldReconnect) {
            console.log('Reconnecting in 5 seconds...');
            setTimeout(() => startBot(), 5000);
        }
    }
});

3. Memory Management

javascript

// Clear old data periodically
setInterval(() => {
    // Clear conversation cache older than 24 hours
    conversations.forEach((value, key) => {
        if (Date.now() - value.lastUpdate > 24 * 60 * 60 * 1000) {
            conversations.delete(key);
        }
    });
    
    // Force garbage collection (jika pakai --expose-gc)
    if (global.gc) {
        global.gc();
    }
}, 60 * 60 * 1000); // Setiap 1 jam

FAQ

Apakah HP harus nyala 24 jam?

Tidak! Dengan multi-device, bot di server bisa jalan sendiri. HP cukup online sekali dalam 14 hari.

Bagaimana jika server down?

Setup monitoring + auto-restart. Dengan PM2 dan watchdog, downtime bisa diminimalkan.

Berapa uptime yang realistis?

Target 99.9% uptime = max 8.7 jam down per tahun. Achievable dengan setup yang benar.
