This resource is particularly helpful for administrators because it allows them to see how credits are consumed across various operations and features, enabling more informed decisions regarding resource management and budgeting. By analyzing the table, administrators can identify which specific tasks or workflows are consuming the most credits, helping them to optimize usage and plan future activities effectively.

Understanding these insights is crucial for managing budget constraints and ensuring that the organization makes the most out of its allocated credits. This resource allows for a granular approach in tracking and managing credit consumption over time, which is essential for maintaining operational efficiency in using ArcGIS Online.
