In some examples, the capture-index information includes at least one of a cold-aisle capture index (CACI) or a hot-aisle capture index (HACI), and selecting the at least the portion of the capture-index information based on the containment type includes selecting at least one of the HACI or the CACI. In various examples, the instructions further instruct the at least one processor to determine the cooling-performance assessment based on a greater of the CACI and the HACI responsive to determining that the containment type is an uncontained type. In at least one example, the instructions further instruct the at least one processor to determine the cooling-performance assessment based on a lesser of the CACI and the HACI responsive to determining that the containment type is a hot-and-cold-aisle containment type. In some examples, the instructions further instruct the at least one processor to determine the cooling-performance assessment based on the HACI responsive to determining that the containment type is a hot-aisle containment type, and determine the cooling-performance assessment based on the CACI responsive to determining that the containment type is a cold-aisle containment type.
