Three Pillars of Observability
Complementary types of telemetry data.
- Logs: Detailed records of events
- Metrics: Numerical measurements over time
- Traces: Request flow through systems
- Together: Complete picture of system behavior
Effective Logging
Capturing the right information in logs.
- Structured logging (JSON format)
- Consistent log levels (error, warn, info, debug)
- Context in logs (request ID, user ID)
- Centralized log aggregation
- Log retention and search capability
Key Metrics to Track
Numerical indicators of system health.
Distributed Tracing
Following requests through complex systems.
- Trace IDs that follow requests
- Span data for each service/component
- Timing and dependency visualization
- Error attribution across services
- Performance bottleneck identification
Observability Tools
Platforms for implementing observability.
- Datadog: Full-stack observability
- Grafana + Prometheus: Open source metrics
- New Relic: APM and observability
- OpenTelemetry: Standard for instrumentation
- Cloud-native: AWS CloudWatch, GCP Operations
Observability Best Practices
Making observability useful.
