Episode notes
Henrik's Career Journey
- Henrik Rexed started his career as a performance engineer, spending 15 years in this domain.
- He transitioned to cloud-native observability at Dynatrace, continuously learning about new technologies like Kubernetes.
Evolution of Observability Practices
- Observability evolved from metric alerts to contextualized data connecting metrics, logs, and traces.
- This linkage allows faster root cause analysis by following failures through comprehensive trace data.
Fine-tune Instrumentation and Live Debugging
- Use performance engineers or QA teams to fine-tune instrumentation levels for observability.
- Employ Dynatrace's Live Debugger to dynamically add breakpoints and get extra telemetry without pausing production.
