Observability Engineering
About this course
Monitoring tells you something is broken. Observability tells you why. This course covers OpenTelemetry instrumentation, distributed tracing, metrics design, structured logging, collector pipelines, actionable dashboards, and alerting that works.
What you will learn
- Observability vs monitoring: the high-cardinality difference
- OpenTelemetry SDK instrumentation for traces and metrics
- Distributed tracing with context propagation
- Metrics design: histograms, cardinality, and aggregation
- Structured logging with correlation IDs
- Collector pipelines: routing, transformation, and sampling
- Dashboards that answer operational questions
- Alerting: symptom-based, with runbook links
