一覽

Tempo is Grafana's open-source distributed tracing system. It stores and queries traces from microservices to identify performance bottlenecks and failures. Used by DevOps and SRE teams managing complex systems. Salary band: 110–170k USD. Time to learn: 4–6 weeks. Adjacent to observability, Prometheus, and Kubernetes. Lower learning curve than traditional tracing (Jaeger).

什麼是 Tempo Distributed Tracing

Grafana Tempo is an open-source, cost-efficient distributed tracing backend designed for large-scale microservices environments. It ingests traces from applications, stores them in object storage (S3, GCS, Azure Blob), and provides a fast query interface integrated with Grafana. Unlike traditional APM solutions with expensive per-span pricing, Tempo charges only for storage, making it economical for high-volume tracing. Tempo is part of the Grafana Observability Stack (Prometheus for metrics, Loki for logs, Tempo for traces). Together, they provide comprehensive visibility into distributed systems without vendor lock-in.

❓ 常見問題

Why use Tempo instead of Jaeger?
Tempo is newer and optimized for cost and scale. It uses object storage (S3) for traces instead of dedicated databases, reducing infrastructure overhead. Tempo is easier to operate and integrates seamlessly with Grafana/Prometheus.
What's a trace and why do I need it?
A trace is a record of a request flowing through multiple services. Each service creates spans (time intervals). Tracing shows latency bottlenecks, failures, and dependencies. Traces help debug production issues fast.
How does trace sampling work?
Tracing every request is expensive. Sampling collects traces for a subset of requests (e.g., 1 in 1000). Smart sampling can prioritize error traces and slow requests.
Can I integrate Tempo with my existing Prometheus setup?
Yes. Tempo complements Prometheus; they're part of the Observability Stack. Use Prometheus for metrics, Loki for logs, Tempo for traces. All three integrate in Grafana.
What's OpenTelemetry and how does it relate to Tempo?
OpenTelemetry is an open standard for instrumenting applications (metrics, logs, traces). Tempo is a backend that stores and queries OpenTelemetry traces. Use OTel SDKs in your applications to send traces to Tempo.
