Introduction

In the previous chapter, you continued to improve your Splunk search and analytical skills by creating more advanced searches that leveraged more of the deep analytical commands to gain more operational intelligence from the data contained within the logs. In this chapter, you will leverage Splunk's lookup functionality to enrich these results with the data found outside of the logs. You will also use Splunk's workflow functionality to perform some simple actions on the data that you discovered.
