According to the Nutanix Prism Central Guide1, categories are key-value pairs that can be assigned to entities such as VMs, images, blueprints, etc. Categories can be used tofilter, group, and manage entities based on their attributes. To review and clean up all existing categories within the Nutanix environment, the administrator should filter on the name, value, entities, and policies of the categories. The name and value of the categories identify the category type and the category value respectively. The entities show how many and which entities are assigned to the category. The policies show how many and which policies are associated with the category.
By filtering on these information, the administrator can organize the findings and eliminate unused categories. References:
