Reference:
A is the correct answer because selecting "Yes" for both "Split by Entity" and "Filter to Entities in Service" allows you to automatically restrict a KPI to only the entities in its service and generate KPI values for each entity. Split by Entity splits the KPI search results by entity alias fields and calculates a separate KPI value for each entity. Filter to Entities in Service filters out any entities that are not part of the service from the KPI search results. This way, you can ensure that your KPI reflects only the relevant entities for your service and provides granular information for each entity. Reference: [Configure KPI settings in ITSI]
