On a Filter object -- an observation filter UCS Manager uses to decide which child managed objects and property values get included when it reports on a parent object -- cucsObserveFilterFilterPropValue2 is a text (SnmpAdminString) field holding the value the second filtered property must equal for this filter to match. An admin reads this string because it carries the actual identifying detail -- not just an internal numeric ID -- needed to make sense of that specific Filter instance. For example, an admin reviewing Filter entries would look at cucsObserveFilterFilterPropValue2 to see the concrete value rather than a bare object reference.
