Information about Expression MIB Support of Delta, Wildcarding, and Aggregation

Expression MIB Support of Delta, Wildcarding, and Aggregation

Expression MIB adds support of the Delta, Wildcarding, and Aggregation features in the Distributed Management Expression MIB (EXPRESSION-MIB) to Cisco software for use by SNMP.

The Delta function enables the Expression MIB to use Delta values of an object instead of absolute values when evaluating an expression. Delta is obtained by taking the difference between the current value of an object and its previous value.

The Wildcarding function of the Expression MIB allows evaluation of multiple instances of an object. This is useful in cases where an expression needs to be applied to all instances of an object. The user need not individually specify all instances of an object in the Expression but only has to set the “expWildcardedObject” in “expObjectTable” to TRUE for the respective object.

Aggregation is performed using the sum function in the Expression MIB. The operand to the sum function has to be a wildcard object. The result of the sum function is the sum of values of all instances of the wildcard object.

For a complete description of Expression MIB functionality, see the Distributed Management Expression MIB, Internet-Draft, available through the ITEF at http:/​/​tools.ietf.org/​html/​draft-ietf-disman-express-mib-11.
