Overview of this book

Even structured data is useless if it can’t help you to take strategic decisions and improve existing system. If you love to play with data, or your job requires you to process custom log formats, design a scalable analysis system, and manage logs to do real-time data analysis, this book is your one-stop solution. By combining the massively popular Elasticsearch, Logstash, Beats, and Kibana, elastic.co has advanced the end-to-end stack that delivers actionable insights in real time from almost any type of structured or unstructured data source. If your job requires you to process custom log formats, design a scalable analysis system, explore a variety of data, and manage logs, this book is your one-stop solution. You will learn how to create real-time dashboards and how to manage the life cycle of logs in detail through real-life scenarios. This book brushes up your basic knowledge on implementing the Elastic Stack and then dives deeper into complex and advanced implementations of the Elastic Stack. We’ll help you to solve data analytics challenges using the Elastic Stack and provide practical steps on centralized logging and real-time analytics with the Elastic Stack in production. You will get to grip with advanced techniques for log analysis and visualization. Newly announced features such as Beats and X-Pack are also covered in detail with examples. Toward the end, you will see how to use the Elastic stack for real-world case studies and we’ll show you some best practices and troubleshooting techniques for the Elastic Stack.

Understanding Profiler


Profiler is another X-Pack component which has grown out of requirement of understanding how a request performs in Elasticsearch. It provides us with detailed information of how the request has been executed at various stages of the request as sent which can be useful to find why your requests are being served slowly or what causes the requests to return results after a long time.

It is the latest addition to X-Pack and has been introduced in X-Pack version 5.1 itself. It is part of the Dev Tools Page. It utilizes the Profile API which is provided by Elasticsearch. Profile API is used to debug the various information of a request to gather underlying details of how request was served and how result was received. The resulting information of Profile API is a large chunk of JSON which is difficult to understand and make sense of. Therefore, Profiler plays an important part of providing the results of Profile API in form of a visualization which makes it easier to understand...
