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

The configuration merging logic


Configurations in different locations merge behind the scenes into one super-configuration. Luckily, the merging happens in a predictable way and is fairly easy to learn; there is also a tool to help us preview this merging.

The merging order

The merging order is slightly different depending on whether the configuration is being used by the search engine or another part of Splunk. The difference is whether there is an active user and app.

The merging order outside of search

Configurations being used outside of search are merged in a fairly simple order. These configurations include the files to read, the indexed fields to create, the indexes that exist, deployment server and client configurations, and other settings. These configurations merge in this order:

  1. $SPLUNK_HOME/etc/system/default: This directory contains the base configurations that ship with Splunk. Never make changes in $SPLUNK_HOME/etc/system/defaultas your changes will be lost when you upgrade Splunk...
