Observability: logs, metrics and tracing for critical systems

1Introduction

A single request may cross dozens of services; observability infers internal state from emitted data.

2Discussion

Three pillars: logs, metrics and distributed tracing.

3Conclusion

User-centred SLOs reduce alert fatigue; OpenTelemetry provides a vendor-neutral standard.
