Observability and Operations
Logs, metrics and traces with OpenTelemetry, SLOs and burn-rate alerting, incident response, runbooks, telemetry pipelines, safe deployments and capacity monitoring.
1. Observability Foundations
Logs, metrics, traces and SLOs: the signals that tell you what production is doing.
- Logs, Metrics and Traces — What each telemetry signal is good for and how they connect.
- Structured Logging That Scales — Design log events that are queryable, safe and affordable.
- Designing Metrics: RED, USE and the Golden Signals — Pick metrics that reveal user impact and saturation without exploding cardinality.
- Distributed Tracing with OpenTelemetry — Instrument services, propagate context and sample traces sensibly.
- SLOs, Error Budgets and Alerting — Define reliability targets and alert on what users feel.
2. Operating Production Systems
Incident response, runbooks, telemetry pipelines, safe deployments and capacity monitoring.
- Incident Response and Blameless Postmortems — Run incidents calmly and learn from them.
- Dashboards and Runbooks — Build dashboards people actually use and runbooks that shorten incidents.
- Telemetry Pipelines and Observability Cost — Collect, process and route telemetry efficiently with OpenTelemetry Collector.
- Safe Deployments and Change Monitoring — Catch bad changes quickly with progressive delivery and automated analysis.
- Capacity Planning and Performance Monitoring — Spot saturation before it becomes an outage.
