The Health Dashboard Analogy
Hospital patients have monitors showing vital signs:
- Heart rate
- Blood pressure
- Oxygen levels
Doctors know INSTANTLY if something's wrong.
Monitoring gives your servers vital signs!
What Gets Monitored
| Metric | What It Shows |
| CPU | Is the server overworked? |
| Memory | Running out of RAM? |
| Disk | Storage filling up? |
| Latency | Slow responses? |
| Error rate | Things breaking? |
Alerting
When metrics cross thresholds:
CPU > 90% for a sustained period → 🚨 ALERT!
→ Send to Slack, email, PagerDuty
→ Team investigates
Don't wait for users to report problems!
Tools
- Prometheus - Metrics collection
- Grafana - Dashboards
- Datadog - All-in-one
In One Sentence
Monitoring tracks server health through metrics and alerts you before problems become outages.
