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

Using event types to categorize results


An event type is essentially a simple search definition, with no pipes or commands.

To define an event type, first make a search. Let's search for the following:

sourcetype="impl_splunk_gen_SomeMoreLogs" logger=AuthClass 

Let's say these events are login events. To make an event type, choose Settings and then Event types, as shown in the following screenshot:

This presents us with the Event types page, where we view existing event types and, as we want to do here, create a new event:

First, click the button labeled New. Splunk will display the Add New page:

Let's name our event type login.

We can now search for the same events using the event type:

eventtype=login 

Event types can be used as part of another search, as follows:

eventtype=login loglevel=error 

Event type definitions can also refer to other event types. For example, let's assume that all login events that have a loglevel value of error are in fact failed logins. We can now save this into another...
