Cloud-Native Observability with Open Telemetry is a guide to helping you look for answers to questions about your applications. This book teaches you how to produce telemetry from your applications using an open standard to retain control of data. Open Telemetry provides the tools necessary for you to gain visibility into the performance of your services. It allows you to instrument your application code through vendor-neutral APIs, libraries and tools.
By reading Cloud-Native Observability with Open Telemetry, you’ll learn about the concepts and signals of Open Telemetry – traces, metrics, and logs. You’ll practice producing telemetry for these signals by configuring and instrumenting a distributed cloud-native application using the Open Telemetry API. The book also guides you through deploying the collector, as well as telemetry backends necessary to help you understand what to do with the data once it’s emitted. You’ll look at various examples of how to identify application performance issues through telemetry. By analyzing telemetry, you’ll also be able to better understand how an observable application can improve the software development life cycle.
By the end of this book, you’ll be well-versed with Open Telemetry, be able to instrument services using the Open Telemetry API to produce distributed traces, metrics and logs, and more.
