Observability Engineering

A book-shaped table of contents for observability engineering: foundations through architecture, metrics, logging, tracing, profiling, OpenTelemetry, instrumentation, Kubernetes/cloud, data platforms, visualization, alerting, SRE integration, cost, security, platform engineering, AI-driven operations, and MAANG interview preparation — cross-linking existing prometheus/grafana-cloud/kubernetes/sre/platform-engineering notes instead of duplicating them.

2 — Troubleshooting Case Studies

Covers worked troubleshooting scenarios (e.g. a collector agent pinned at 100% CPU) as a rehearsal for live debugging interview questions.

3 — Telemetry Design Exercises

Covers exercises in designing the telemetry (metrics/logs/traces/labels) for a given service from scratch, a common interview format.

4 — Incident Walkthroughs

Covers narrating a real incident timeline and RCA in interview-answer form, structured for a behavioral or systems-thinking question.
