In this chapter, we have created a Hadoop connector and virtual index for CDR data. As a result, we got a chance to explore that data using the Hunk interface and the Splunk Search Processing Language. In addition, we learnt how to create reports, dashboards, and alerts. Finally, we considered the authentication approach to Hunk, which allows us to manage the security of Hunk, users. In the next chapter, we will learn about the rich functionality of Hunk such as data models, pivots, and various knowledge objects.
