Notification Systems

Notification Systems

Escalation Chain Design

Level 1: Log to file          (always — silent)
Level 2: Dashboard warning    (PM2 status + frontend)
Level 3: Telegram message     (via julia-relay or direct bot)
Level 4: Repeat + urgent tag  (3x in 10 min → URGENT prefix)

Julia's Notification Pattern

// Notify Raphael via bridge → OpenClaw → Telegram
async function notify(message: string, level: 'info' | 'warn' | 'alert' = 'info') {
  const prefix = level === 'alert' ? '🚨 ALERT' : level === 'warn' ? '⚠️ Warning' : 'ℹ️ Info';
  await fetch('http://localhost:3001/incoming', {
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify({
      chatId: process.env.RAPHAEL_CHAT_ID,
      text: `${prefix}: ${message}`,
      source: 'julia-system'
    })
  });
}

Deduplication (avoid alert storms)

const recentAlerts = new Map<string, number>();
function shouldAlert(key: string, cooldownMs = 600_000): boolean {
  const last = recentAlerts.get(key) ?? 0;
  if (Date.now() - last < cooldownMs) return false;
  recentAlerts.set(key, Date.now());
  return true;
}

Notification Rules for Julia

• On service down → alert Raphael immediately
• On service recovered → info message (resolved)
• On security finding → warn (daily) or alert (critical)
• On task completed → info (optional, user preference)
• Rate limit: max 1 alert per 10min per service
