Migrating from OpenTracing to OpenTelemetry - Kubernetes Community Days Munich 202
- 1. 1 Is now a good time to migrate from OpenTracing/OpenCensus to OpenTelemetry? Sonja Chevre, Senior Product Manager Kubernetes Community Days, Munich 2022
- 2. 2 Hallo Mnchen! Reach me on Twitter: https://twitter.com/SonjaChevre
- 4. Who knows OpenTelemetry and feels con?dent with distributed tracing? 4 Who uses OpenTelemetry in production?
- 5. Mobile application Web application API Gateway Account service Inventory service Shipping service Account DB Inventory DB Shipping DB Web application API Gateway Inventory service Inventory DB
- 6. Observability platform Web application API Gateway Inventory service Inventory DB Web application OpenTelemetry SDK API Gateway OpenTelemetry SDK Inventory service OpenTelemetry SDK Inventory DB Trace 123 spans id=123 id=123 id=123
- 8. Observability is a must-have feature of cloud native software 8
- 9. 1. Is it valuable for our users? 2. Is the technology ready yet? 3. How much e ort will it take us? 9
- 10. Cultural shift: it is now less about logs and more about traces
- 11. Signal and language status Collector Java JS .Net Python Go Ruby C++ PHP Traces Metrics Logs GA GA GA GA GA GA GA In Progress In Progress In Progress GA In Progress In Progress GA RC RC RC Beta (User API RC) Beta
- 12. What are the options? 1. Bridge OpenTracing API to the OpenTelemetry SDK 2. OpenTelemetry collector to convert the traces to OTLP format 3. Start from scratch and rewrite the whole instrumentation
- 13. How valuable is our current instrumentation?
- 14. What happens inside an API Gateway? Web application Version check Rate limit check Authentication Requests to upstream APIs Process responses Modify response Inventory service Pricing service API Gateway REST GraphQL
- 15. What does a deployment look like? Web application Reverse proxy API Gateway API Gateway API Gateway
- 16. 5 questions to ask yourself before (re)instrumenting your service 16
- 17. Which context propagation should you implement? Web application API Gateway Inventory service id=123 id=123 Web application API Gateway Inventory service id=123 trace-id=xw39s
- 18. 1. W3C Trace-Context 2. Zipkin B3 3. Custom / proprietary (AWS X-Ray) Context propagation: the options Web application API Gateway Inventory service id=123 trace-id=xw39s W3C Trace Context ZipKin B3 AWS X-Ray
- 19. How much detail should you expose?
- 20. User-related attributes Customer segment, customer ID, geo data, device type, OS version Software-related attributes Deployment ID, A/B-testing, feature ?ags, version Data-related attributes Request/response size, whether a cache has been used, caching timestamps Infrastructure-related attributes Host ID, OS, data centre, orchestration (cluster, pod, or node IDs) Use attributes that can explain performance variation
- 21. You should pay careful attention to exactly what data is added to your spans as they can potentially contain personally identi?able information (PII) Are you exposing PII data?
- 22. Which sampler to implement?
- 23. 1. AlwaysOn 2. AlwaysOff 3. ParentBased 4. TraceIDRatioBased Sampling - the options
- 24. How much overhead will be added by the instrumentation?
- 25. Dont hesitate to get help from the community Share what you learn 25
- 26. Building best-in-class, built-in observability for our users To observe, monitor, troubleshoot and analyse their API usage To monitor and troubleshoot their Tyk Platform
