4. AGENDA 1. Challenge Distributed Tracing 2. Solutions 3. Showcase Minikube 4.Architecture 5. Real World Example
5. CHALLENGE DISTRIBUTED TRACING 1
6. 7 CHALLENGE DISTRIBUTED TRACING Example Architecture
7. 8 CHALLENGE DISTRIBUTED TRACING What happens if an Error occurs?
8. 9 CHALLENGE DISTRIBUTED TRACING What makes it difficult to find the error? • Error is not logged • Logs are not accessible • Request can’t be tracked • Error != Performance Issue • Where is the bottleneck • …..
9. 10 CHALLENGE DISTRIBUTED TRACING Solution: Monitoring of Systems • Logs: Textual records generated by software applications • Metrics: CPU, Memory, Error rates, … • Alerts: Notifications generated by monitoring systems • Dashboards: visual representation of monitoring data • Traces
10. 11 CHALLENGE DISTRIBUTED TRACING What is a Trace? • Capture execution flow • Request / Transaction path with time • End-to-end visibility
11. 12 CHALLENGE DISTRIBUTED TRACING Example Architecture
12. SOLUTION 2
13. 14 SOLUTION What is a Trace-ID? • Often referred as X-Correlation-Id • Unique Identifier assigned to a trace • Correlate and track the flow of a request or transaction • HTTP-Header in case of HTTP-requests
14. 15 SOLUTION Where/When create a Trace-ID? • ASAP you have the possibility • Check Trace-Id available • (y) – use the existing one • (n) – create one and propagate it
15. 16 SOLUTION Source of error • Every component must stick to the rules • Every component = potential single point of failure • Solution: OpenTelemetry / Jaeger
16. 17 SOLUTION What is OpenTelemetry • Project under Cloud Native Foundation (CNCF) • Standardization of telemetry data • Telemetry data: logs, metrics, traces • APIs and SDKs to generate data • A lot of programming languages supported
17. 18 SOLUTION What is Jaeger • Tool for analyisis of storage and visualization of trace data • Uses OpenTelemetry data
18. 19 SOLUTION How does a Trace look like • A trace represents data / execution path through system • Acyclic graph of spans
