Class Hierarchy : DISMANEXPRESSIONMIB ExpResource

This class represents state data.

expresourcedeltaminimum

The minimum expExpressionDeltaInterval this system will accept. A system may use the larger values of this minimum to lessen the impact of constantly computing deltas. For larger delta sampling intervals the system samples less often and suffers less overhead. This object provides a way to enforce such lower overhead for all expressions created after it is set. The value -1 indicates that expResourceDeltaMinimum is irrelevant as the system will not accept ‘deltaValue’ as a value for expObjectSampleType. Unless explicitly resource limited, a system’s value for this object should be 1, allowing as small as a 1 second interval for ongoing delta sampling. Changing this value will not invalidate an existing setting of expObjectSampleType

expresourcedeltawildcardinstancemaximum

For every instance of a deltaValue object, one dynamic instance entry is needed for holding the instance value from the previous sample, i.e. to maintain state. This object limits maximum number of dynamic instance entries this system will support for wildcarded delta objects in expressions. For a given delta expression, the number of dynamic instances is the number of values that meet all criteria to exist times the number of delta values in the expression. A value of 0 indicates no preset limit, that is, the limit is dynamic based on system operation and resources. Unless explicitly resource limited, a system’s value for this object should be 0. Changing this value will not eliminate or inhibit existing delta wildcard instance objects but will prevent the creation of more such objects. An attempt to allocate beyond the limit results in expErrorCode being tooManyWildcardValues for that evaluation attempt

expresourcedeltawildcardinstanceresourcelacks
