What is 'data onboarding' in Splunk?

Data onboarding in Splunk refers to the process of acquiring and preparing data to make it usable for analysis within the Splunk platform. This involves several steps, including collecting data from various sources, transforming it into a usable format, and ensuring it is indexed correctly so that it can be queried and analyzed effectively.

The importance of data onboarding lies in creating a seamless flow of data into Splunk in a structured and efficient manner. Proper onboarding ensures that data is enriched with relevant metadata, properly categorized, and aligned with the specific needs of the user's queries and dashboards.

In contrast, the other options represent different aspects of data management or analysis that do not focus specifically on the processes involved in acquiring and preparing data for use in Splunk. Analyzing data, visualizing data, or deleting unused data are distinct operations that occur after the data has been successfully onboarded into the system.
