This object controls which alMatrix[SD/DS] entry that the alMatrixTopNEntries are sorted by, which view of the matrix table that will be used, as well as which table the results will be reported in. The values alMatrixTopNTerminalsPkts, alMatrixTopNTerminalsOctets, alMatrixTopNTerminalsHighCapacityPkts, and alMatrixTopNTerminalsHighCapacityOctets cause collection only from protocols that have no child protocols that are counted. The values alMatrixTopNAllPkts, alMatrixTopNAllOctets, alMatrixTopNAllHighCapacityPkts, and alMatrixTopNAllHighCapacityOctets cause collection from all alMatrix entries. This object may not be modified if the associated alMatrixTopNControlStatus object is equal to active(1).
