Alerting
🔹 Overview
Alerting systems detect events and notify users or systems when defined conditions are met.
They are critical for identifying issues, triggering responses, and maintaining system awareness.
🎯 Scope
- Threshold-based detection
- Notification methods
- Escalation workflows
🧠 Key Concepts
- Alerts are only as good as the detection feeding them
- Poor tuning leads to alert fatigue
- Alerts should be actionable, not informational noise
- Escalation ensures critical events are not missed
⚙️ System Design
Thresholds
- Define meaningful trigger conditions
- Avoid overly sensitive thresholds
- Tune based on real-world behavior
Notifications
- Push notifications
- Email / SMS
- System integrations (webhooks, APIs)
Escalation
- Primary notification → user
- Secondary notification → backup contact/system
- Time-based escalation for unresolved alerts
⚠️ Common Mistakes
- Too many alerts (alert fatigue)
- Poorly defined thresholds
- No escalation strategy
- Alerts enabled before detection is stable
- Treating all alerts as equal priority
