Logging, metrics, tracing, correlation IDs, and operational visibility for APIs.
Practice items tagged with Observability.
Turns a production-only role and payload failure into the smallest durable API regression test.
Separates application composition in AppHost from reusable in-process defaults for telemetry, health, resilience, and service discovery.
Explains rate-limit identity, endpoint cost, login and suggestion throttles, Redis counters, user experience, and observability.
Explains why sensitive admin actions need authorization, reason capture, before/after context, and tamper-resistant audit records.
Explains API keys, client credentials, managed identity, mTLS, scopes, rotation, and per-client observability.
Explains trusted tenant context, membership checks, tenant-scoped queries, cache keys, and background job propagation.
