Implementing Splunk 7, Third Edition - Third Edition

Overview of this book

Splunk is the leading platform that fosters an efficient methodology and delivers ways to search, monitor, and analyze growing amounts of big data. This book will allow you to implement new services and utilize them to quickly and efficiently process machine-generated big data. We introduce you to all the new features, improvements, and offerings of Splunk 7. We cover the new modules of Splunk: Splunk Cloud and the Machine Learning Toolkit to ease data usage. Furthermore, you will learn to use search terms effectively with Boolean and grouping operators. You will learn not only how to modify your search to make your searches fast but also how to use wildcards efficiently. Later you will learn how to use stats to aggregate values, a chart to turn data, and a time chart to show values over time; you'll also work with fields and chart enhancements and learn how to create a data model with faster data model acceleration. Once this is done, you will learn about XML Dashboards, working with apps, building advanced dashboards, configuring and extending Splunk, advanced deployments, and more. Finally, we teach you how to use the Machine Learning Toolkit and best practices and tips to help you implement Splunk services effectively and efficiently. By the end of this book, you will have learned about the Splunk software as a whole and implemented Splunk services in your tasks at projects

Planning your installation


The following are a few questions that you need to answer to determine how many Splunk instances will be involved in your deployment:

  • How much data will be indexed per day? How much data will be kept? The rule of thumb is 100 gigabytes per day per Splunk indexer, assuming that you have fast disks. See the Sizing indexers section for more information.
  • How many searches will be running simultaneously? This number is probably smaller than you think. This is not the number of users who may be using Splunk, but the number of queries that are running simultaneously. This varies by the type of queries that your group runs.
  • What are the sources of data? Where your data comes from can definitely affect your deployment. Planning for all the possible data that you might want to consume can save you from trouble later. See the Common data sources section for examples.
  • How many data centers do you need to monitor? Dealing with servers in multiple locations introduces another level...
