Summary
Corporations are discovering the value of analyzing big data to give insight into users behavior. This analysis has yielded results that have proven useful in various fields, including education, medicine, and computer security. In this chapter, we explored the use of Splunk to tackle big data problems. We looked at how data generation has changed over time. We looked at how Splunk has been used in organizations to solve problems. We also reviewed the key components of Splunk – forwarders, indexers, and search heads. We learned that forwarders send data to the indexers, which index the data. Users use Splunk search heads to create search queries in SPL. These search heads create knowledge bundles that they send to the indexers. The indexers search their indexes for data that match the queries. They return the results to the search heads. These components work together to give powerful results.
Finally, we introduced our BOTS dataset v1 dataset, which was generated for the Splunk BOTS competition and is a rich dataset for this exercise. We will use examples from this dataset throughout the rest of this book.
We will deploy our Splunk environment in Chapter 2, Setting Up the Splunk Environment, which will consist of a search head, an indexer, a deployment server, and three forwarders.
