To get a better overview of how much each resource costs (or a resource group or a location), you can use Cost analysis to get a personalized view of different spending categories. Besides the main chart representing the accumulated view, you will have access to three additional charts, which you can alter to get a different categorization of resources:
Figure 1.34 - Cost analysis per service name, location, and resource group name
There are many interesting categories that you can use to understand the cost—you can divide services using tags, their tiers, invoice number, or even their GUIDs. If you have many resources, this becomes especially helpful as it allows you to use advanced filtering and better distinction.
