Part 4
4 chapters
Production concerns
Cardinality and cost, the service graph and SLOs, a production readiness checklist, and where to go from here.
Chapter 21
Cardinality and cost
How unbounded label and attribute values drive up storage and query cost across metrics, logs, and traces, and how to control spend at the Collector.
Chapter 22
Service graph and SLOs
How a service graph is derived from spans, how span metrics and the four golden signals feed SLOs, and how to alert on them.
Chapter 23
Production checklist
Rollout patterns, per-environment resource attributes, keeping secrets and PII out of telemetry, and the path from this local stack to a managed backend.
Chapter 24
What's next
OTLP profiles as the emerging fourth signal, eBPF-based auto-instrumentation, the wider OpenTelemetry ecosystem, and where to read further.
