Network observability has emerged as a critical evolution of traditional monitoring, providing the deep visibility needed to manage today’s complex, dynamic environments. In Modern Network Observability, authors David Flores, Christian Adell, and Josh VanDeraa share their extensive experience to guide you through building and deploying a flexible observability stack using open-source tools. This book begins by addressing the limitations of monolithic monitoring solutions, showing you how to transform them into a composable, flexible observability stack. Through practical implementations, you’ll learn how to collect, normalize, and analyze network data from diverse sources, build intuitive dashboards, and set up actionable alerts that help you stay ahead of potential issues. Later, you’ll cover advanced topics, such as integrating observability data into your network automation strategy, ensuring your network operations align with business objectives. By the end of this book, you'll be able to proactively manage your network, minimize downtime, and ensure resilient, efficient, and future-proof operations.What you will learn Collect and normalize data from various sources using Telegraf and Logstash Enrich operational data with crucial context from a Source of Truth such as Nautobot Visualize data and create insightful dashboards with Grafana Automate alerts and responses for your network operations strategy using Prefect Understand when to build or buy an observability stack, with tips and best practices Explore practical machine learning techniques to enhance observability data value Who this book is forThis book is for all network engineering roles such as network analysts, administrators, architects, security personnel, support staff, and managers working in both on-premises and cloud environments who are tasked with implementing or using network monitoring solutions. Basic programming knowledge in Python and Go, familiarity with networking concepts, and a fundamental understanding of Docker containers for lab scenarios will be required.

Network engineers are finding it harder than ever to rely solely on manual processes to get their jobs done. New protocols, technologies, delivery models, and the need for businesses to become more agile and flexible have made network automation essential. The updated second edition of this practical guide shows network engineers how to use a range of technologies and tools, including Linux, Python, APIs, and Git, to automate systems through code. This edition also includes brand new topics such as network development environments, cloud, programming with Go, and a reference network automation architecture. Network Programmability and Automation will help you automate tasks involved in configuring, managing, and operating network equipment, topologies, services, and connectivity. Through the course of the book, you'll learn the basic skills and tools you need to make this critical transition. You'll learn: Programming skills with Python and Go: data types, conditionals, loops, functions, and more How to work with Linux-based systems, the foundation for modern networking and cloud platforms Data formats and models: JSON, XML, YAML, and YANG Jinja templating for creating network device configurations The role of application programming interfaces (APIs) in network automation Source control with Git to manage code changes during the automation process Cloud-native technologies like Docker and Kubernetes How to automate network devices and services using Ansible, Salt, and Terraform Tools and technologies for developing and continuously integrating network automation

Explore network automation with Ansible by configuring network infrastructure fast, reliably, and repeatedly, all while creating a lab utilizing open and available network operating systems and tools Key Features Design, build, and automate network devices and cloud networking resources using Ansible Orchestrate workflows with AWX and integrate Nautobot as a Source of Truth Start with Event-Driven Ansible and manage Terraform workflows seamlessly Purchase of the print or Kindle book includes a free PDF eBook Book DescriptionNetwork Automation Cookbook, now in its second edition, is your essential guide to building robust network automation workflows across modern hybrid infrastructures. Building on the foundation laid in the first edition, this version dives deeper into Ansible’s role in automating network infrastructure, expanding coverage to include modern use cases across enterprise and cloud networks. The book introduces Ansible’s core concepts, such as playbooks, inventories, variables, loops, and templates, and progresses to advanced topics such as parallelism, fact caching, custom filters, and modular design. You will automate real-world scenarios using Nokia SR, Cisco IOS, Juniper, and Arista devices in a fully reproducible virtual lab. The chapters also help you explore cloud automation for AWS, Azure, and Google Cloud, and integrate validation tools such as PyATS, Batfish, and Nautobot. New chapters cover event-driven automation, AWX for workflow execution, and Terraform integration. By using hands-on labs and fully reproducible recipes, you can practice real-world scenarios and reinforce your skills. By the end of this book, you’ll be well-equipped with the tools and workflows to automate infrastructure efficiently with Ansible.What you will learn Build Ansible playbooks, roles, and inventories from scratch Automate Juniper and Arista network devices Deploy cloud networks on AWS, Azure, and Google Cloud Validate networks with Batfish and NAPALM Use AWX for workflow automation and job scheduling Integrate Nautobot as a dynamic inventory source Run all recipes in containerized, hardware-free labs Apply event-driven automation using Ansible Rulebooks Who this book is forThis second edition will help network engineers, DevOps pros, cloud architects, automation engineers, and NREs understand Ansible’s role in network automation and how it integrates with tools like Terraform and event-driven architectures. The book requires basic networking knowledge and familiarity with YAML to maximize learning.

Transform the way your network teams think about and deploy enterprise network automation through the power of Nautobot's open-source platform Key Features Learn how documenting your network in Nautobot can accelerate your network automation journey Apply NetDevOps to your network by leveraging Nautobot as a network source of truth Minimize tool sprawl by extending, using, or building Nautobot Apps Purchase of the print or Kindle book includes a free PDF eBook Book DescriptionNautobot enables network teams to build a scalable and extensible network source of truth that provides a foundation to power any network automation stack. With the help of this guide, you’ll learn how to deploy, manage, and integrate Nautobot as a source of truth and network automation platform. As you progress, you’ll learn what a network source of truth is, the relationship between data and network automation, and network data models. You’ll also gain a broad understanding of Nautobot and its robust features that allow maximum flexibility. A dedicated section will show you how to construct a single source of truth with Nautobot and help you explore its programmatic APIs, including REST APIs, GraphQL, webhooks, and Nautobot Job Hooks.
