Overview of this book

Splunk provides a platform that allows you to search data stored on a machine, analyze it, and visualize the analyzed data to make informed decisions. The adoption of Splunk in enterprises is huge, and it has a wide range of customers right from Adobe to Dominos. Using the Splunk platform as a user is one thing, but customizing this platform and creating applications specific to your needs takes more than basic knowledge of the platform. This book will dive into developing Splunk applications that cater to your needs of making sense of data and will let you visualize this data with the help of stunning dashboards. This book includes everything on developing a full-fledged Splunk application?right from designing to implementing to publishing. We will design the fundamentals to build a Splunk application and then move on to creating one. During the course of the book, we will cover application data, objects, permissions, and more. After this, we will show you how to enhance the application, including branding, workflows, and enriched data. Views, dashboards, and web frameworks are also covered. This book will showcase everything new in the latest version of Splunk?including the latest data models, alert actions, XML forms, various dashboard enhancements, and visualization options (with D3). Finally, we take a look at the latest Splunk cloud applications, advanced integrations, and development as per the latest release.

Index

Application data

Now that we have created a new App, we can start working on how we need our data indexed. Typical Apps may contain configurations for their own indexes, source types, and other input methods.

Indexes

Indexes are very useful in a new App as they allow you to physically separate the data on the disk on the indexers. This helps speed up searches and optimizes macros and event types, since only a smaller subset of data will be searched within the App. The configurations of the indexes are in the indexes.conf file, in the default folder. For our App, let's add an index. The configuration looks like this in the indexes.conf file, located at $APP_HOME/default/indexes.conf:

[splunk_developers_guide]
coldPath = $SPLUNK_DB\splunk_developers_guide\colddb
homePath = $SPLUNK_DB\splunk_developers_guide\db
thawedPath = $SPLUNK_DB\splunk_developers_guide\thaweddb

That's it! Defining indexes is a quick way of optimizing your App's data. You can also create indexes using the GUI...
