Monitoring & Observability
Build comprehensive observability for your systems.
The Three Pillars
1. Metrics (Prometheus)
# Instrument your app
http_requests_total{method="GET", endpoint="/api/users", status="200"} 1024
http_request_duration_seconds{quantile="0.95"} 0.235
2. Logging (Loki / ELK)
- Structured JSON logging
- Include: timestamp, level, service, trace_id, message
- Centralized log aggregation
- Log levels: DEBUG < INFO < WARN < ERROR < FATAL
3. Tracing (Jaeger / Tempo)
- Trace every request across services
- Span: individual operation with timing
- Distributed context propagation via trace ID headers
- Sample 1-10% of production traffic
Alerting (Alertmanager)
Alert Severity
| Severity | Response Time | Channel |
|---|---|---|
| Critical | Immediately | PagerDuty + SMS |
| Warning | 1 hour | Slack + Email |
| Info | Next day | Dashboard |
Golden Signals (Google SRE)
- Latency: Time to respond
- Traffic: Requests per second
- Errors: Error rate (5xx, exceptions)
- Saturation: Resource utilization
Dashboard Design (Grafana)
Rules
- 3-5 panels per row
- Time series with trend lines, not raw numbers
- RED metrics: Rate, Errors, Duration per service
- USE metrics: Utilization, Saturation, Errors per resource
- Include annotations for deployments, incidents
Best Practices
- Monitor from outside (synthetic checks)
- Monitor everything, alert on what matters
- Use SLOs to define what's "good enough"
- Test alerts (fire drills, tabletop exercises)
- Review dashboards monthly with the team
