What is the function of a Search Head in Splunk?

The function of a Search Head in Splunk is to enable users to run searches and visualize data. This component serves as the interface through which users interact with Splunk's search and reporting capabilities. When users submit queries, the Search Head processes these requests, coordinates with indexers to pull in the relevant data, and then presents the results in an easily interpretable format, often through dashboards and visualizations.

The Search Head is essential for facilitating data analysis and insights since it provides the tools for creating searches, reports, alerts, and visualizations, allowing users to derive meaningful information from their data. This role is critical in a Splunk deployment, particularly in environments where users need to analyze large volumes of data quickly and efficiently.
