What is the purpose of the "fieldsAdd" function in DQL?

The "fieldsAdd" function in DQL (Dynatrace Query Language) is specifically designed to enhance and enrich query results by appending calculated fields. This functionality allows users to include additional information or metrics in their results, which can be vital for deeper analysis and insights. By using "fieldsAdd," analysts can create new fields derived from existing data, enabling them to better understand performance metrics, service dependencies, or any other relevant data points that offer greater clarity or context.

The other options serve different purposes not aligned with the function of "fieldsAdd." Organizing data hierarchically or deleting unnecessary fields focuses on structuring or cleaning up data rather than enhancing it. Converting raw data into visual formats pertains more to data representation than to the modification of data through enriched fields. Hence, the option related to appending calculated fields accurately captures the essence and functionality of "fieldsAdd" within DQL.
