1Introduction
A single request may cross dozens of services; observability infers internal state from emitted data.
2Discussion
Three pillars: logs, metrics and distributed tracing.

Logs are sensitive: mask card numbers and personal data, as OWASP warns, and restrict access.
3Conclusion
User-centred SLOs reduce alert fatigue; OpenTelemetry provides a vendor-neutral standard.
