Main Functions of Splunk Enterprise :

1. Index Data — The index collects data from virtually any source. The indexer takes in random data and decide how to process it. Once they decide on that, they label the data with a source type. The source type is then used to break the data into single events. Then the timestamps are identified of the events and normalized to a consistent format. The events are then stored into the Splunk index.
2. Search and Investigate — Events, that contain values across multiple data sources, can be found while entering a query into the Splunk search bar, which allows use to analyze and run statistics on events using the Splunk Search Language.
3. Knowledge Objects — These can be added to the data. It allows you to affect how the data is interpreted, give it classification, add enrichment , normalize it and save it for future use.
4. Monitor and Alert — Splunk has the ability to proactively monitor all the infrastructure in real time to identify issues, problems, and attacks before they impact customer and services. Alerts can be created to monitor for specific conditions and automatically respond with a variety of actions.
5. Report and Analyze — Splunk gives the option to collect reports and visualizations into dashboards, empowering groups in your organization by giving them the information they need, organized.
