Grafana Tempo architecture: from collectors to object storage and queries

A source-backed practical IROSG IT guide.

Grafana Tempo architecture: from collectors to object storage and queries

Scope

This original IROSG guide covers معماری distributed tracing با Grafana Tempo using the cited primary documentation.

Core model

Tempo spanها را از protocolهای tracing می‌گیرد، آن‌ها را distribute/ingest می‌کند و blockها را در object storage نگه می‌دارد. query path برای پیدا کردن trace و correlation با metric/log از مسیر نوشتن جداست.

Practical workflow

Trace ID را بین serviceها propagate کنید، resource attributeهای پایدار بسازید و sampling را براساس هزینه و نیاز incident تنظیم کنید. Collector را به‌عنوان buffer/processor مستقل از application نگه دارید.

Failure modes

Sampling تهاجمی ممکن است دقیقاً trace incident نادر را حذف کند. attribute پرکاردینالیتی، PII و payload حساس نیز نباید بدون policy وارد telemetry شوند.

Lab

سه service آزمایشی با OpenTelemetry بسازید، latency مصنوعی در service دوم ایجاد کنید و trace end-to-end را در Tempo پیدا کنید. سپس sampling را تغییر و اثر را مقایسه کنید.

Production method

Capture a baseline, change one variable at a time, test positive and negative paths, preserve evidence, and rehearse rollback before broad rollout.
