3. Agenda ⊸ What’s Thanos ⊸ Why try Thanos & Key

   features ⊸ Design ⊸ Demo ⊸ Conclusions

4. What’s Thanos?

5. HA metric system with unlimited storage capacity for

6. What’s Prometheus

7. Monitoring system & time series database (時間が少ないので省略)

8. Why try Thanos? And Key Features

9. メトリクスデータを オブジェクトストレージ に保存できる Why try Thanos? POINT!! Reliable metrics data

   storage

10. 複数Prometheusの メトリクスデータを マージし閲覧できる Why try Thanos? Global view POINT!!

11. ロングタームなクエリの応答性を維持 するため、メトリクスデータをダウンサ ンプリング Why try Thanos? Downsampling

12. 依存コンポーネントが少なく 既存のPrometheus環境に 追加することが簡単 Why try Thanos? Seamless integration

13. Design

14. Querier(Thanos) Prometheus targets Sidecar(Thanos) Prometheus Sidecar(Thanos) targets targets targets Merge

    & Deduplicate targets targets targets targets Global view HTTP API

15. SSD Prometheus Sidecar(Thanos) targets targets targets Blocks targets targets targets

    Blocks Blocks targets targets targets Blocks targets targets targets Blocks Unlimited retention! Write

16. Unlimited retention! Read targets targets targets Blocks Cache Store(Thanos) targets

    targets targets Blocks Querier(Thanos) Store API

17. targets targets targets Blocks Disk Compactor(Thanos) targets targets targets Blocks

19. Use Case

20. Only Backup Disk Prometheus Sidecar(Thanos) targets targets targets Blocks targets

21. Querier(Thanos) Prometheus Sidecar(Thanos) Prometheus Sidecar(Thanos) HA or Aggregate

22. targets targets targets Blocks Querier(Thanos) Prometheus Sidecar(Thanos) All Store(Thanos) Compactor(Thanos)

23. Demo

24. None

25. Notice

26. Prometheus >= v2.0.0 可能であればv2.2.1

27. Conclusions

28. 2018/07/04時点 Thanos has no official releases yet

29. まだまだ動作検証中！ （カジュアルに使う分には問題ない）

30. 導入前には本当に長期間の保存 が必要か確認！？ • 不要なデータを削減 • スクラップ間隔と保存期間を見直す • KPIデータは別のストレージを検討 • 古いデータの価値（YAGNI）

    場合によってはPrometheusだけでも十分！
