OpenTelemetry

• Code-based, Zero-code 要背
  • https://opentelemetry.io/docs/concepts/instrumentation/
• API, SDK 定義要看
  • https://opentelemetry.io/docs/concepts/components/
• 架構圖要熟
  • https://opentelemetry.io/docs/collector/
• 必考
  • https://opentelemetry.io/docs/concepts/context-propagation/
• OpenTelemetry Protocol (OTLP) 好像有兩題
  • https://opentelemetry.io/docs/specs/otel/protocol/
• 第一張圖要看一下 receivers, processors, exporters 要知道能幹嘛，還會考 connector
  • https://opentelemetry.io/docs/collector/architecture/
• 考兩題
  • https://opentelemetry.io/docs/concepts/semantic-conventions
• 兩個詞 題目會出現
  • https://opentelemetry.io/docs/concepts/signals/traces/#tracer-provider
• API 與 SDK 的差別
• Span、Trace、Metrics、Logs 的架構與用途
• Receivers、Processors、Exporters、Connectors 四個 component 的主要用途，還有資料的處理順序
• Extensions 的角色
• Pipeline 最少需要哪些 component (Receivers + Exporters)
• 常見 Processor (Batch, Memory Limiter, Schema Transform, etc.) 的用途
• 使用 otelcol Debug / Validation 的方法 (otelcol validate –config)
• Instrumentation 導入程式碼的方式，要修改 code 或是不修改 code 的方式
• SLI -> SLO 的定義方式
• OTLP 預設的資料格式 (Protobuf + JSON 並透過 gRPC 或 HTTP 之類的)
• Telemetry 資料如何處理
• Scaling Collector 的正確方式 (水平擴展 replicas + load balancer)
