Build cloud native observability pipelines with minimal footprints and high-performance throughput—all with Fluent Bit, Kubernetes, and your favorite visualization and analytics tools.
Logs and Telemetry is an all-practical guide to monitoring both cloud-native and traditional environments with the Fluent Bit observability tool. It takes you from the basics of collecting app logs, all the way to filtering, routing, enriching and transforming logs, metrics, and traces.
Within the world of Kubernetes, there are probably as many opinions on what is involved in Kubernetes monitoring as there are flavors of Kubernetes. This book looks at all the major Kubernetes features available at this writing, but don’t expect it to be a comprehensive guide on, say, building Helm charts for Fluent Bit. (For that, read a book about Helm first and then read this book. This will give you an understanding of how to package Fluent Bit, which is no different from any other application.) More of us work with prepackaged Kubernetes stacks than build Kubernetes environments from scratch. These configurations are opinionated, so if you know how they’re configured, this book will equip you with the understanding to capture those metrics, logs, and traces. In its most basic form, Kubernetes is a clever and highly configurable application process running on a configurable OS. Keeping this in mind and seeing a lot of Fluent Bit’s standard features will help you.
Inside Logs and Telemetry you’ll learn how to:
Deploy Fluent Bit for telemetry (log, metric, and trace) collection
Configure pipelines to filter, route, and transform data
Integrate Fluent Bit with containers and Kubernetes
Configure Fluent Bit to work with OpenTelemetry, Prometheus, and other open source tech
Monitor applications at scale with minimal footprint
Address challenges in Kubernetes-based ecosystems using Fluent Bit
Utilize Fluent Bit for real-time event analytics to derive new metrics and insights
Develop custom filters, inputs, and outputs for unique or reusable use cases
Logs and Telemetry draws on both the input and support of key committers and founders of Fluent Bit, and author Phil Wilkins’ years of experience in DevOps. Inside, you’ll see how you can integrate Fluent Bit with Prometheus, OpenTelemetry, FluentD deployments, and more. Learn how Fluent Bit can not only meet all the demands of cloud-native use cases, but also more traditional deployments as well.
about the technology:
Fluent Bit is a super-fast lightweight observability tool that’s perfect for Kubernetes and containers, as well as traditional IT environments. Fluent Bit makes it a snap to extract meaning from the logs, traces, and other performance metrics generated by your applications and infrastructure. It’s also a great way to route telemetry to analysis tools like Prometheus and Grafana.
about the book:
Logs and Telemetry shows you how to turn systems data into actionable insights using Fluent Bit. You’ll start by learning the pre-built plugins for common use cases and progress to integration with powerful tools like OpenTelemetry and real-time analytical event processing. You’ll use plugins to configure routing, filtering and processing, automate your observability with Lua scripts, and configure Fluent Bit to meet the demands of highly scalable environments.
