This is the normalValue property of a 32-bit threshold definition object, the definition of one 32-bit-valued statistics threshold, i.e. the bounds for a counter like utilization or an error rate, that belongs to a threshold policy, the baseline value UCS Manager treats as the expected/normal reading for the counter this threshold governs. An admin sets this baseline so that UCS Manager's threshold engine has a reference point for detecting abnormal deviation, separate from the specific up/down trigger points also defined on this threshold. For example, on a threshold guarding CPU or fan utilization, setting normalValue to the figure typical for that hardware under normal load helps distinguish routine variation from a real problem.
