Learn to design, implement, and scale distributed observability in Rust using OpenTelemetry, with practical examples for tracing, logging, and metrics.
Key Features:
- Implement end-to-end observability in Rust using OpenTelemetry APIs and Collector
- Correlate logs, traces, and metrics across async, multithreaded Rust applications
- Build and deploy an observable Rust microservice with Actix, Redis, and Prometheus
- Configure dashboards, alerts, and trace views in Grafana using real telemetry data
Book Description:
Gain the skills to build, monitor, and debug distributed systems in Rust with this hands-on guide to observability using OpenTelemetry. As Rust adoption grows in backend services, developers face fragmented documentation and limited tooling for telemetry. This book fills that gap by presenting a unified, end-to-end solution to implement distributed observability in modern Rust systems.
You'll explore the foundations of observability and Rust's ownership model before learning how to collect, export, and correlate logs, metrics, and traces. Discover how to instrument applications using OpenTelemetry crates and bridge them with the tracing ecosystem. Learn to deploy the OpenTelemetry Collector, integrate with Prometheus, Grafana, and Jaeger, and tackle challenges like sampling, context propagation, and async tracing.
Written by two seasoned engineers with over 35 years of combined experience in large-scale systems and open-source observability leadership, this book balances theory with real-world implementations. From debugging async bottlenecks to configuring cost-effective telemetry pipelines, you'll finish with the confidence to operate reliable, observable Rust systems at scale.
What You Will Learn:
- Understand the three pillars of observability in Rust
- Apply tracing and logging using the Tokio and OpenTelemetry crates
- Export telemetry to backends like Prometheus, Jaeger, and Grafana
- Use the OpenTelemetry Collector to manage telemetry pipelines
- Correlate metrics, logs, and traces for faster debugging
- Implement structured logging, redaction, and context propagation
- Optimize telemetry costs with sampling strategies
- Build and deploy an observability-first Rust microservice
Who this book is for:
Rust developers building backend systems, DevOps engineers, and SREs deploying Rust in production will benefit from this book. Ideal for readers experienced in Rust development who want to implement end-to-end observability using OpenTelemetry and tools like Grafana, Prometheus, and Jaeger.
