Use this practical guide to the Splunk operational data
intelligence platform to search, visualize, and analyze
petabyte-scale, unstructured machine data. Get to the heart of the
platform and use the Search Processing Language (SPL) tool to query
the platform to find the answers you need. With more than 140
commands, SPL gives you the power to ask any question of machine
data. However, many users (both newbies and experienced users) find
the language difficult to grasp and complex. This book takes you
through the basics of SPL using plenty of hands-on examples and
emphasizes the most impactful SPL commands (such as eval, stats,
and timechart). You will understand the most efficient ways to
query Splunk (such as learning the drawbacks of subsearches and
join, and why it makes sense to use tstats). You will be introduced
to lesser-known commands that can be very useful, such as using the
command rex to extract fields and erex to generate regular
expressions automatically. In addition, you will learn how to
create basic visualizations (such as charts and tables) and use
prescriptive guidance on search optimization. For those ready to
take it to the next level, the author introduces advanced commands
such as predict, kmeans, and cluster. What You Will Learn Use
real-world scenarios (such as analyzing a web access log) to
search, group, correlate, and create reports using SPL commands
Enhance your search results using lookups and create new lookup
tables using SPL commands Extract fields from your search results
Compare data from multiple time frames in one chart (such as
comparing your current day application performance to the average
of the past 30 days) Analyze the performance of your search using
Job Inspector and identify execution costs of various components of
your search Who This Book Is For Application developers,
architects, DevOps engineers, application support engineers,
network operations center analysts, security operations center
(SOC) analysts, and cyber security professionals who use Splunk to
search and analyze their machine data
